Im toying with the idea of putting a 454 into my project car. then i noticed that really a weiand supercharger undriven kit(as this would be a often used car) wasnt that far out of my price range.

with all that said would putting a 454 and supercharger be worth the effort? or would i have to do some serious relocation to make it fit, and by serious i mean would it cost so much time and money that really it wouldnt be worth the effort.

if there is alot of relocation that is required would a supercharged 350 fit without relocation?

 

Relocation?

Using a supercharger on top of the engine, about your only modification required would be to cut a hole in the hood.

 

the relocation was whether it would fit in the bird, as its tight with a 305/350 for the most part and putting a 454 and supercharger i thoughtwould take up more room forcing me to relocate the motor mounts or radiator.

 

Bulletproof the 305 you have and go with a good turbo setup.

With the right crank rod piston setup 305 or 350 and a good turbo
probably do as good or better than the BB and retain handling for
street use.

while ive considered that, if i dont go with a bbc supercharger ill go with a sbc supercharger, and ill end up putting a 350 anyways. i dont plan on doing much but dragging the car however i do want to be able to take it out on a nice night and cruise. however this wouldnt be a daily driver thus the whole idea of a 454 came into play.

 

Forced induction at 15-psi literally doubles cubic inch displacement. So the question is, would you rather run a 350-SBC @ 15-psi and get 700 cubic inches to play with, or a 454-BBC @ 15-psi and get 908 cubic inches to play with. Either one will get the job done, but if your worried about fitment issues, then go with the former....

 

You stated it would be a often used car.
These cars set up rite for the street are very good handling cars.
Had #2 1st gen Zs I put BBs in, one a OC L88 and screamed but
when it came to handling, forget it. Plus heating and other assorted
problems.

They did generate a lot of oohs and ahhs when you opened the hood
tho.

honestly i dont know if there are fitment issues so im hoping one of you guys can tell me that. if its a almost flawless drop in for the most part with no motor mount and firewall modifications its the 454 no question.

 

what problems did you run into with heating? i think my opinion of often used and others is different maybe? i was thinking alot on the lines of 1 a week or so, and for handling what was the deal? im not looking to do any street x stuff of any kind, mostly just go fast in a straight line. since you have experience with bbc in a thirdgen and didnt seem to like it im all ears.

 

It's been done countless times, and the only real issue is header fitment, but then again you can get any credible fabricator to make you a custom set to your liking. Other than that, it drops right in. Here is one of my favorites (try not to drool)....;

dang thats a nice maro, i think i need to try and be more specific and please dont take me as rude i done mean to be but i was fairly certain about the fitment of a 454 working my question was more based on a supercharged 454 fitting as i was fairly certain the supercharger added some length along with pulley relocations. and i want powersteering and all that jazz to fit.

 

If you look down about 4 threads on BBC header install
it will give you a good idea as to what you will be getting into.
It is not just a drop in and go.
There will be issues and compromizes.
(Money) and time will cure most of them.

Good Luck

Other considerations besides the exhaust are going to be the cooling system, the fuel system, transmission, and the rear differential....All are going to require some upgrades.... Going from a poochy stocky 305 to a supercharged anything will wreak havoc on everything in the rest of the drivetrain that is now going to be subject to 500+ horsepower and was originally designed for 200 horsepower.... The engine and blower are by no means the end of items for your budget!!!!!

 

Oh they fit alright....;

But I think your looking for something more like this, right, but with a BBC....?

The sticky for installing a BBC into a third gen is here

https://www.thirdgen.org/forums/engi...swap-info.html

Putting a supercharger on it doesn't affect the installation of the BBC other than hood clearance. As mentioned above, the rest of the driveline will also need to be upgraded to handle all that power. From a 396 to a 540, installation is all the same using the short deck block and a short deck 540 can be punched out to a 598 but the stroke gets excessive in the short deck block. If you want a tall deck block normally used for a 572 or 632 then installation becomes a little more difficult.

I get lots of oohs and ahhs when I open my hood to reveal a BBC with a tunnel ram.

 

I've done the BB swap,as well.What you haven't specified,is are you talking about a Roots type supercharger,or a centrifical?It is a bolt in deal,other than minor mods to fit headers.If you retain the heater/AC box,that will give you the most grief.

 

im looking to use a roots type supercharger and reatain the heater and ac

 

Go BIG BLOCK!!!! I've had all combinations, this is my last combo. I love the big block in my car. People love it too at car shows and the power is incredible. People talk about small-blocks and I used to do the same until I got a big block. I had a supercharged small block in the car going low 11's, so my small block ran well. I don't want a small block again.

I can tell you it's not a problem to run a small block with the 6-71 setup and still retain the heater and a/c. The only thing I don't have on mine any more that it did from the factory is the cruise control (and emissions of course). If I had to do it all over again and money was absoutely no object, I would put a blown big block in it. The only issue that I could see would be the heater-a/c box. But there again, throw enough money at it and it too can be solved. As far as a daily driver, you will be sorry if you drive it on a daily basis. That's alot of polished aluminum to maintain. Seeing out the windshield is also an issue. That big ol blower creates one heck of a blind spot.

 

the heater box on m 89 clears just about perfect, but i dont have ac. i lined an old ac box off my 84 up while doing some mocking up, and theres some clearancing needed, especially with taller than stock valve covers. the other area i the windshiled wiper motor. again, possible contact with taller valve covers. heating can be solved with a good twin electric fan, be-cool 4 core rad, and a good aluminum water pump, as well as a cowl hood (but you already got that supercharger hole planned.) be-cool sells a reletively bolt in rad good for 700 hp that comes with twin 1800cfm fans, the wiring and relays, the fully fabbed 4 core rad, and a few other things, its about 1200 bux. a worth while investement if you asked me. it also has the tranny cooler for the auto-peeps out there (not that youd wanna bog down the radiator with that job)

 

Did you ever get it done .... if so did a stock cowl hood fit or did you have to cut it

 

I put a LS based 4.8 in it, turbo'd it. Got divorced and sold it.

 

Proof that talking to you was a waste of time, which is why I didn't chime in. You don't even have a 3rd gen.

 

Well excuse the **** out of me and my million year old post guy. Go be a looser elsewhere. I went with the better combo can you blame me? Oh wait you won't chime in......
