what will I need to build a double blown 394?

Okay I've got a '62 or 3 Olds 394 Sky Rocket and am planning on using it in my '38 Pontiac g***er project, I have ditched a few projects to do something do what I really want to the old Poncho... My main focus right now is getting the engine set up the way I want it before I dig into the car..

I want to go all out and make this car SUPER WILD, I plan on running 2 blowers pyramid style... What I want to know is what's needed to turn the old rocket into a blower motor? what would you recomend for parts? cam? pistons? blowers? injection?

Now this might sound odd...But I want it to be 100% streetable, so can I crank the boost down low enough on the blowers?

I know nothing about blower motors if that helps any...But I can learn!

Thanks for the help,
Bobby

P.S. let me know if I'm missing something too..

 

A wallet with an ATM card that has direct access to AIG bailout money.

So far as I know the only way you adjust a blower is by changing the speed that it turns via different size drive pulleys. With two blowers you might need to use spare rims for pulleys to get them down enough to have a streetable combination. Okay, I'm exaggerating, but still I'd bet on a need for either hard to find or custom made parts. Twin blower cars weren't that common in race form that I remember, they have to be a bear to tune and make work reliably. (Seems to me some of the show cars with that setup were cars that didn't even run!)

 

Hi Bobby
Give me a call we biuld a lot of early Rocket stuff and I have a lot of pieces for them.

Let us know how strong the blower surge is at idle. I've always wondered about what a twin blown roots car would do in that regards.

AIG bailout is about right. What's that, $8k of blower and drives and carbs? And you know it's gonna be polished so maybe I'm low. Cha-ching!

 

Dare I suggest youd also need cojones the size of watermelons....

 

I agree on the bail out money, I know it's gonna be expensive...But, it will all be worth it in the end..I kind of figured that's how you'd slow 'em down or speed 'em up by changing pulleys, I started a pic request thread on Double Blowers and there are some sweet ones that run...

Tony, I'll get in touch with you, I've got to talk to you about rockers for a 303 too.

Nope not polished, I want to paint the the blowers blue with silver&gold flake just like the rest of the car is going to be, and polish the ribs/fins...I've got carbs, stacks of AFB's and odd 2 barrels.

Damn, guess I can't do it now........


Okay, lets keep this going! any more info? what size blowers should I use? 4-71? 6-71? 2-53? What brand of blowers to use?

 

Well a 394 and two blowers would be a good start!

There has been two double blown cars that were street driven over here. Rod Hadfields T Coupe with two on a shotgun 427 (6-71s Driven very little, showcar) and Robin(sp?) Kirby's old 34 Plym coupe with two on a Hemi, 6-71s again. Both were cantankerous things, Kirby's kept shredding blower belts and drive lines on the 1/4 mile, **** that seems a long time ago around the 87 Canberra Nationals and at Heathcote dragway the same weekend Mark Georgette rolled the Topolino. I guess this is more a memory lane thing for Aussies. Kirby went back to a single blower and improved performance a hell of a lot!
Then ended up running a Top Fuel car, you could be heading in the same direction! How much $$ you got??
Oh, then there was Gary Meyers Mustang with two stacked one on the other (8-71s?), ran like **** and with BIG cubes he couldn't sort it out enough to get it to fry the bags, needless to say he went back to one real quick. I think it was done for shock value to debut the car.
It can be done but will never run well unless you sink bookoo $$ and development time into it.
Id run a single for driving/racing and have a dummy double for show if I had the fundage.
Doc.

 

I've got the 394, need the 2 blowers...It seems like the idea of it ever running "right" is never going to happen...I was thinking of running 2 gutted blowers...but what's the point of paying a lot of $$$ for something that doesn't work? If anything I am going to run a 1, but I just have dreams of a 'lectric blue '38 Poncho blastin' down a strip with 2 blowers screaming.....I guess I spend to much time looking at **** on Uncommon Engineering's site.

Thanks for crushing my dreams lol, I am going to run a single though seems a little more within my reach.

 

A fat wallet and bad taste. Two blowers on one engine looks stupid.

 

You have to be incredibly rich and stupid at the same time. Twin blowers are for ***holes that say hey,look at me...

 

Sorry dude, but hey....
kirbys coupe did look *****in!

 

Bad idea..........screams look at me! Big watch, little **** syndrome.

 

What if one of them were hollow inside - One that did all the work and the other just for looks?

 

If ya do it, call me. I wanna come over to witness this ****er...
I suppose you could weld up a triangle shaped intake and mount the blowers on a 45 degree angle, next to each other. I've seen that done before...have no idea how well it worked but it makes more sense than stacking them...imagine the heat of the compressed air going into the 2nd blower to be further compressed and heated again on a stacked arrangement.
If you put 'em side by side, blowing into a common plenum, the heat would be less I'd think..

 

OOOO. KKKKKKK., we tried this waaaaaay back in the day. Several big problems;
1. Blower drives.....you gonna be eating belts like there's no tomorrow....not to mention the stress on the crank.
2. If they're gonna be big blowers, gonna have mixture issues, because of the angles if you try to stand them kinda on the edge.
3. Your engine isn't gonna run good at low RPM to mid rpm.....big parasitic loss at the crank.......

We tried this already.....it ran.....didn 't run good....we know it looked stupid and believe me, it was. We just finally ran 2 dummies with a tunnelram crammed up in all that ****......

If you want a blown engine......build one. Use a 6-71 or a 8-71 on you bigblock, sink all that extra money you got into a fuel injection system to sit atop the blower, put a good steel crank in it, some steel H-beam rods, Aluminum heads and block, a totally custom ground roller cam.............it'll look killer, run like a top, not to mention all the respect you'll get from a properly setup killer blown bigblock,,,,,,,,.......

 

when your car is equipped with two blowers, that should be one under the hood and one in the front seat with your arm around her. Although two under the hood is probably cheaper in the long run.

 

You Da Man!!!!!!!!!!!!

 

when back in the day this was tried to have the boost w/o spinning the blowers faster &raising the heat level...now they are using 2 to 4 big turbo's ....check out tractor pull set ups

 

I would bet you would have more than 18 thousand in a set up like that not to mention all the head aches that you will have to over come. Good luck with your idea

 

but I don't have enough room for another engine!

 

Steel H Beam rods? Aluminum Heads? and block? custom roller cam? WOW if you can find all this stuff for a 394....you would be my hero!

A blown BBC would be pretty mean, but I'm stayin' with the Olds, and I'm just gonna run 1 6-71.

 

My thought exactly.
Could build it cool for less and have more fun.

 

lmao!

 

Ya see guys,
I told ya they were a**** us!!!!!!!!!!!
1 word
S T U P I D !!!

 

you want to build a blown olds with 2 blowers. and you dont know anything about blowers. when you do things just to pretend your different or "out there" this is the kind of dumb idea people come up with. its been tried its not streetable and a waste of your brain to even think about it. but hey its your brain. why dont you do something to really show people how smart you are and really build the car instead of pretending. think of it this way, if tom beatty wouldnt do its a waste of time and other peoples' time trying to help. here's a thought. build a single blown olds with a 4-71 and a couple 97's and dont worry, evryone will be impressed instead of just looking at the car and saying gee what a waste of an extra blower. sorry for the rant but i just upped my meds . good luck and via con Dios..

 

"Steel H Beam rods? ALUMINUM HEADS, custom roller cam? WOW if you can find all this stuff for a 394....you would be my hero!"
-----------------------------------------------------------------------



You would like these things for your Oldsmobile Rocket?
I can be your hero,Dont forget the stroker kits too.

Tony

 

Damn, you guys have everything!!

except for a website for me to drool over...

Now I have to get in touch with you...

 

Had Roth do a shirt to give to a friend who owned a blown T with sbc years ago.
He couldn't stop talking about that thing (beers). It was a guy driving the T with
a Jimmy blower for a head and said BLOWER FACE above the pic. Very *****'n

 

Hey dude.....they're out there, you just gotta look........be suprised what the folks that do aluminum heads have heads for! And blocks.......I'm not allowed to say names and all......just the business I'm in......Sorry!!!!

 

I could sell you my Magnacharger Mc-220 twin blower setup with twin 50mm weber side drafts, Ive got blowers, carbs, throttle linkage, idler pulley top and bottom, all you need is a crank hub and a 4bbl intake. $3500.00
