The motor is a 292 Chevy inline 6 going into a 1949 Chevy pickup. And, while everyone's still reading, I have done A TON of research and the specs you see are what I want. The N/A motor will put out around 300HP and 300ft.lbs. The turbo and blown ones will put out around 400of each. If I run it Naturally Aspirated it will have:Edelbrock 500cfm 4bbl, Offenhauser intake, lump ports, 1.94int. and 1.50 exh.valves, Ross Pistons, 9.5:1 compression, long tube headers, and here's the cam specs: 274* advertised duration, .320 cam lift, 110* lobe center. If I turbo it it'll have: Holley 500cfm 2bbl in a blow thru setup, Clifford intake, lump ports, 1.94int. and 1.60exh valves ross pistons, 8.5:1 compression, Tom lowe's turbo manifold, TO4B Turbo and here's the cam specs: intake: 268* advertised duration, .304 cam lift,114* lobe center. Exhaust:264* adv.duration,.296 cam lift. And If I go the blower route it'll have twin 350CFM Holley 2bbl's for a draw thru setup, Custom intake, lump ports, 1.94I/1.60E valves, Long tube headers, Ross Pistons, and a 6-71 Blower (because I have one). Here's the cam specs for this one: lift@1.7:I).500"E).510" Adv.duration:I)272*E)280* Cam Lift:I)294"E)300" lobe center:115* Duration@.050:I)224"E)230" Depending, I may run Snow Performance's water methanol injection on either the turbo or blower, whichever I want to go with... I'm kinda leaning toward the blower route, but that may change...
A six on a turbo is wonderful. 'Course normal aspiration is good too. A turbo six can often get away with no muffler. Don
Here's the link for Snow Performance: http://www.snowperformance.net/products.php?p_cat=324&offset=0 I was going to run the stage 1 boost cooler setup, dual nozzles, and the boost byp*** solenoid. maybe add the safe injection kit later... Any ideas on how this might work?
Those things put out awsome torque my brother has 1 in a 63 suburban with edelbrock 4bl headers cruise and vintage air
Please, Please do your homework and see if you can't install the Pontiac Sprint 6-banger SOHC head COMPLETE w/ the Q-Jet and factory split exhaust manifolds on it AND THEN hop it up!! pdq67
The stock 292 head can be made to flow quite well actually, and with a SOHC setup I'd have to rig some kind of gearing to operate the cam...
Up date: Here's some mods I made to the set up after some more research: 4 1bbl rochesters, 6-71 blower, 10#'s boost, homemade intake manifold, lump ports, 1.94&1.60 valves, Ross or Arias custom pistons, 8.0:1 compression, homemade dual 3" exhaust, MSD BTM ignition, Snow performance's Water/Alky injection, 200,000psi rods, ss roller rockers, and Here's my cam specs: lift@1.7:i).500"E).515" Adv.duration:i)272*E)280* Cam Lift:i)294"E)300" lobe center:115* Duration@.050:i)224"E)230"
I am sending my love out for 6 cylenders.. especially the one in my 55 chevy van its going to make a 1000 mile trip in 4 days...
you can make a lot more than 300 horsepower with a carb, check out my cousin's and mine on the" can you say hot rod six cylinder" thread. Kevin Self did the lump port heads on both of these engines. Make sure you don't forget to use a real good balancer, or you'll regret it .We use ATI supers with a #88 durometer rubber, ATI will special make them and ship for a little over $400, And red loc***e the flywheel bolts also. Good luck on your bad *** six ! Don
Do you have a copy of Leo Vantussi's(Sp?) great 6-banger book?? If so, follow what he says. Now, back to the SOHC Pontiac head, why the problem because everything will be stock except for the needed longer timing belt, imho. Now if you really want to get serious here, then think about sawing up say at least three, if not four double-hump SB heads and then furnace brazing them back together to come up with a 6-banger cross-flow head that haul's the mail.. Hell, if you want a one-off SOHC pieced together SB headed jobber on a 6-banger, then contact Pete Ardema and have fun!! And have you really read about and understand why guy's use the smaller, shorter stroked, engine cranks because of harmonics and **** like that for high rpm 6-banger race engines. You buy a dedicated race 292 crank and you should be good to go, but using a stock 292 crank you may see it come un-glued at high rpm, and this is jmho.. pdq67
Ya, I won't rev it above 5200 for just that reason. I've already ordered Leo Santucci's book TWICE! once from Barnes and Noble, and once from the motor bookstore. so I figure one of them should come sooner or later... at this rate it's already later I think I'll just lump port the stock head, if not for the simplicity, then for the sheer proven reliability. IIRC leo had TONS of problems with head gaskets. and I have not the time or money, or even remotely close to the time or money he had. I'm not trying to disagree with anyone on here, just looking for the simplest route through a complex build... thanks again guys, keep it comin!
Someone mentioned the Australian Ford 6's . This is the current evolution turbo 6 in our Falcon's . This is a hopped up version from Nizpro in Melbourne . 1100 hp at the flywheel . http://www.youtube.com/watch?v=6RpGKP_FsTc
Guys... The Twin Turbo ballot is reserved for the chrysler straight eight, yes eight, that I just got for FREE yesterday. It's flathead, and I'm thinking really low compression, really high boost. Not sure If I should dump the 292 build for now and put this in my 49 chev truck or what... Any info on these? It came out of a crane and says "Chrysler Industrial Engine" right on the side of it...
I really think the blown six is an awesome setup. I don't think you'll be displeased at all with it. I would stay the course.
I'd run it blown, and set it up with a road warrior setup so if you can't get fuel you can drive to the next gas station. I would definately spray it. Forced air has a tendency to get hot. You probably already know this but be sure to O-Ring the block and have your valves ground with broad flat surfaces.
I've already responded to your posts over on HotRodders.Com, so that does'nt need repeating. Have you checked out Inliners International on the net? Strictly inline engines on that side. My vote is still with a single, exhaust driven, turbo setup. And the offer still stands. Butch/56sedandelivery (AKA junior stocker on HRs.Com).
I've been posting on the inliners site for a while now, and pretty much have my build lined out. BTW: what offer?
I've talked to larry(T6) alot, email mostly, and he's helped a bunch. I'm sure he'll see this eventually, so when you do, Thanks Again!

The turbo route is the best bang for the buck but I would make it injected, much easier to tune, and carbs can be hard to deal with on a turbo car. if you have to use a carb find a Maserati biturbo setup
O.K. Quinton, I copied and mailed the article today. Take their approach, add the repo'd Fenton cast iron headers, a Clifford intake with a BIG Holley 2 barrel, blow through turbocharger setup, and a few standard upgrades; it's what I'd do. Butch/56sedandelivery. The "other" consideration would be to buy a late model, totaled, Chevrolet/GMC with the straight six (I think it's a six, but it could be 5 cylinders; I DO NOT keep up with new cars/trucks), and swap the entire drive train into your 49. But, none of this talk is really "traditional", as the focus of JJ.Com is. Good luck. Butch/56sedandelivery.
Thanks again Butch, I thought about the newer sixes (4.1L?) but I really don't think EFI and all the other ECU stuff would look right in a truck from the 1940's... To tell you the truth I'm having a hard time putting all the MSD, Water/meth Injection, and a big fat blower on it, let alone fuel injection. I'm thinking of running 2or3 V belts on the blower instead of a big fat blower belt, just for the looks...
Anyone know where to get a ?custom? V-belt drive for a 6-71? I'm talking about running the blower off v belts....
