What does it take to make a gasser engine?

I don't know squat about gassers, enlighten me.

 

me too, while youre at it...

 

I've got a project 55 Chevy with a 454 (mice livin in the motor!), my dad & I been sittin on it for about 6 yrs. After seein how trendy 55's are now, I told him I wanna somethin a little different, i wanna do it up like an old gasser. Right now it has a 'glass front end, 10 pt cage, and a 5.13 geared 57 pontiac rear. The guy we bought it from raced it in the 70's (he had a tunnel rammed 327 in it). I'm thinkin I beam axle, radius the rear wheel openings, and then Hilborn injection (converted to EFI) on a BIG (500+ cid) big block (tell everyone it's a 427, then it's cool ) Still in the dreamin stages right now, but it shouldn't be too long...

 

cool man, deffinately hook up the 55 as gasser!

but lets say you want to run in the class, whats it take?... are there certain spec's the motor/car needs to have?

 

Step one would seem to be to pick a specific tine period and then get an NHRA (or whatever) rule book from that year and read the gas class section. Some reading of period magazines with coverage of events would also be useful.

 

I think the whole concept of a gasser is to build a bad ass motor that still runs on gasoline, thats where the word comes from, as opposed to a "fulie" car. Then there were different classes within the gas class for blowers and injection and stuff. I think thats pretty much how it works, but I don't really know...I wasn't around back then.
Like Hot Rod to Hell, I also have a 55 post that (if Big Ric or his friend doesn't buy it) will end up with a blown 472, straight axle and all the other bad ass shit that makes a car totally impracticle for street driving.

 

You need to get ahold of whatever sanctioning body you'll be racing with. Each group has different rules. You should be able to find most of the class rules on the web, but if not, I'm sure the organizations will be more than happy to SELL you a rule book!

 

main ingredients, fenderwell headers with exhaust cut outs, tunnel ram or blower, healthy motor with alot of cam!

 

Hey, Hot Rod To Hell, I thought a 454 was a RAT motor not a Mouse motor? [ QUOTE ]

Kind of a wide open ???, but here goes- ANY motor from the period your looking at buicks and BIG time Olds + Pontiacs,baby hemi's to 392's and of sbc/bbc,It was a time when inovation and experimentation was the norm , some things worked and some did not and were passed over,My 57 gasser had both 327+ 396/4 spd. at dif. times, my 56 delivery had a PONTIAC lrg CI motor/4 spd,not to mention the SBC and BBC(mostly later) built with ALL period pcs including Isky roller cams , hydro + stick 4 spds + alum BBC/327 PG's(yes, they were there too), inductions ran tha gamat from stack fulies to 3,4+6 carbs,tunnel rams,cross rams, and finally blowers(in certain classes, HIGH rpms were the norm and 5 grand starts were kool , so they built em TOUGH, to live in that environment, DEEP rear gears like 5:13 to 6:10's, posi's were'nt around til later(well, they were but the periods current tech made em undependable), but spools and locking spiders were the rule.Truck rears , Olds /pontiac rears and Chrys. 8 3/4's were the preffered usage.9" were there but very few as tech had'nt made them popular yet, hope this helps.well said already but get a time period rule book , (forget NHRA) they are no help and MOST gassers will not be able to run NHRA w/o serious safety legal upgrades that will and do ruin the gasser character unless you stay 12.0. or slower (whats the point?)AND you WILL run against Mustangs and camaros in the BRACKETs classes, I was informed of this at B.I.R.'s 4 july race,I was also told by one track official that they are NOT interested in going BACKWARDS,Funny considering it was these vary cars that BUILT NHRA and made spectatorship popular, read that as $$$$-Mike

 

Screw the NHRA. No, more like screw the modern NHRA. They are too busy cashing in on sponsers to care what the racers are doing.

From what I understand, the Gas class was supposed to be what appeared to be street legal cars running on gas. Beyond that I don't think it matters if it was a big cube hemi powered '33 willys or a 265 55 chev, as long as it looked like it had head and taillights.

I'd like to find out the exact rules for the gas altered and super stock classes around 1962 or 1963. I've searched my catalog of hot rods and such, and the only info I've got is what racers used on their cars that were shown in the articles.

Like Mike said, 300+ cube motors, high revs, 57 olds and pontiac rears, hydros and stick trannys were in. Who ever had a reliable car and came up with something new seemed to win, and next week everyone had his new inovation. Make sure its got a bunch of carbs, a small fuel tank, masking tape numbers on the doors, and super sticky recap tires. Dave

 

This is my "Gasser", 90% done.
In the beginning....
The class was for street driven (no trailers), street legal (glass,wipers,exhaust systems,full interior) cars with a minimum of a 90 inch wheelbase. You could put any 6 or V8 engine in it, headers, 4 speeds and hydromatics.
The classes were based on Pounds-per-cubic inch.
Later on, supercharged classes were also offered.

 

To continue...
My car is based on the '59-'61 era, Chevy 385 stroker engine, 4 speed,fenderwell headers,White and Red pleated interior, 100% street legal, pie-crust rear tires on steel rims, old Ansen front wheels.

 

im just about to start on my gasser project. its a57FORD 2 door wagon .im using 55 F-100 front axle and leaf springs ,cutting off the stock front frame and replacing with 2x4 tubing ,relocating the rear spring inboard and using lift bars , not going to tub it or anythng just going to put the widest tire that will fit probably a max of 11 inches .noinner fender wells in front with fenders and hood welded together and hinged at the front. big block , fenderwell headers . heres a before shot of it.

 

right on for the info's/pics guys! now i just need mike L's 57 gasser, slap my big block/400 in there, and im ready to roll

 

How's this? A 292 with 327 "462" heads, Hilborn injection, S&S fenderwell headers, Cal Custom covers, Moon timing cover and pan and a Vertex mag. Just need to install the NOS Packard 440 wires.

at least 10 grand... i think
seriously: see TRJ # 15

 

10 g's? naaaaahhh.... guess it would really depend on how fast you want to go or how well you can hide the nitrous plumbing

Pounds per cubic inch dictated what class you ran in along with maximum engine set back, measured from front axle centreline to No1 plug. Worth getting a hold of Supercharged Gas coupes by Don Montgomery. He covers alot of the rules for A/GS B/GS C/GS that were enforced. Initialy I think the shortest wheelbase allowed was 100" but then it changed to 90" thats when the Anglia's and Austins became popular and the guys in the bigger cars tried to get then outlawed, then they tried to get them to race in the unblown classes. 90" + lots of HP = Good Time !

 

An engine could look like this one that was in my 57 gasser-now slated for the 56, It was that attitude from NHRA that helped convince me that an all drag car (tho licensed) is not for me,Hence the 56 delivery street/drag car, If I can't go as fast as my car is able AND maitain period coerrectness, I'm NOT interested anymore.Things like hoop bars and belts I can see, but 8-10 points -NOT

 

I did race back in that era, so I'm probably qualified to give this question a fair shot. Any engine can be a "Gasser Engine", that was not the criteria that established the Gas Class. In the early 60s, Junior Stock was a huge class and rules allowed for any combination of factory equipment to be utilized in a body by the same manufacturer. Example, I used a 57 Chevy nine passenger stationwagon, the one with three rows of seats, excellent weight transfer, 283 H.P., 283 cubic inch bored to 292, which was legal in stock classes, .010 overbore. Four speed and a 5:13 Chevrolet rear end, Doug headers and a few other mods. The car was a record holder in F/S. In the later part of the 60s NHRA rules changed, which in effect, took some of the best and fastest cars out of competition, including me. The rules were changed to only allow for equipment combinations that were offered in the body being used, obviously the 283 fuelie motor was not an option in the 9 passenger wagon. My choices would have been to use a "power pack", single four barrel engine and either a powerglide or three speed off the column to continue to compete in a stock class. Back then there was also a class known as pure stock, the cars had to be show room perfect with essentially no modifications, the class sucked! In the same period, there was also a class called Modified Production, in this class you could take an essentially stock car, install an aftermarket camshaft, larger then stock specs and have to run M/P. I had a 55 Nomad with a 365 H.P. 327, Muncie 4 speed, Hooker headers, 5:13 gear, etc., and ran E/MP. That class destinction was determined by weight to cubic inch ratio. Modified Production was just that, a modified production passenger car with a limitation on the modifications. An example of the limitations were such things as suspension modifications or even removing the bumpers. I took the front bumper off of the Nomad one weekend and the car fell into D/Gas. So came to be the Gas Class; streight axels which afforded us better weight transfer with the nosebleed atitude, multiple carbs, Hilborne and other injections were popular and no blowers. The blower cars fell into a class of their own. Stone, Woods & Cook, K.S. Pittman, Ohio George Montegomery, etc. ran A/GS or later AA/GS and again, the class determination was made considering cubic inch to weight ratio. The main difference between Gas and M/P, was that in Gas, you could run any body / engine combination. In one of the previous posts in noticed a Willys being built as an old style Gasser and I'll use that as an example, I've seen that same body run F, G & H Gas with 6 bangers or small displacement V-8s of many varities, I've also seen it run A/G and A or AA/GS with blown Hemis or Ford 427 Cammers. So..............Gasser Engine? Bone stock 283 in a Henry J, and it doesn't have to be sky high in the front end to be a Gasser, using the old criteria. Not trying to be a smart ass, but I think what I see, rather then an engine issue, is guys trying to replicate "The Look", and one of the most commonly used configurations was the I beam axel, slicks extending out past the sheet metal, narrow front wheels without brakes and Hilborne stacks sticking up through the hood. Now, this should draw some fire...................all those mods that replicate the desired look are great on the 1320 but on the highway will certainly offer the opportunity for a "Death Rod"! I spent last weekend at Indy and my observation of the Pro Mod cars of today is this, they are a direct spin-off of the AA/G Supercharged cars of the past, the biggest difference being that they don't run nitro as a fuel.

The little Thames panel in the previous post is more then likely a A/GS car. Big blower motor in a light vehicle. If you were to take the carbs off, add injection on the top of the Blower and use Nitro, now were talking AA/GS. Huge attention getters of the past and a handfull to drive.

I, for one, appreciate the specific info offered up by Mr. Copeland.
I didn't run back then, I just watched.

I'm pretty darned sure they didn't use nitro in gassers in the '60s. Gassers were just that - gassers. As I recall, the blown cars were A/GS, B/GS and C/GS. This may have been changed to AA/G or AA/GS and so on. The disclaimer here is that I didn't run a gasser back then, only lived and raced during the era. I also had much more experience with AHRA than NHRA, but I still maintain that gassers ran gas. The photo is one of my favorite gassers, the Nail and Holzman B/GS car that ran at our local track and was a record holder. This car is still owned by the Holzman family and is still raced weekly by the original Holzman's grandson. However, it is a naturally aspirated bracket car now, but it still has the look.

 

Shoe, you are the man...

iam afraid ta go fasta, docta! wouldnt how fast you want to go depend on the pocket book size? at 17 i worked my ass off for about 6mo. just to add $3k+ worth of engine specific gear, tools, machining (including breakage)... i probably should add ...ignorance enduced fuckups, and getting proper tools to the equation.

Was I the only teenager who lusted for Morticia Addams?


shit no, and she was probably in her 50s by the time it was my turn.... that broad was the template for your modern goth sluts! THANKS YOUS MORTICIA

 

ill iterate what caballo said... shoe, you are the man...

 

Shoe is correct, that is how i remember em as well,There is a lot of misinfo that ALL gassers had fenderwells and straight axles or Ball joint spacers when nothing could be further from fact.that era only lasted a short time and was in fact not even an era, but a few years only, exaust cutouts (the cable kind , not the current electrics,were from a previous era - FLATHEAD- and none that I remember ran em , most the ones I recall had lakes plugs or 3 bolt dumps out the side off of the headers and (for a street car)full exaust back or simply flipped up and bolted out of the way, The M/P classes were in fact a lot of fun as they were "our" cars that we drove to school/work etc.AND affordable,as racing gets anyway-NEVER cheap in ANY era except in comparison to now, when the average garage guy pulled a whole $1.25 an hour compared to $9-10 now.

 

here is my 56's front suspension, originally 60's done and era correct.
