My name is Cody Stafford. I have a 1968 Plymouth barracuda completely restored. the engine has all aftermarket parts on it to keep its original stock 318 performance. Now i have been looking into it and im wondering what all would have to be done to install a supercharger/blower. Im not going to be running it down a track or lead footing it i want it for show. Im just wondering if going to a junkyard and getting a used but working blower would be worth it. Im just going for the look and function. It doesnt have to boost my engine im just looking for show. Its got a 318 in it. My grandpa installed all aftermarket innards. Pistons cam rods. the heads have been redone aswell. I know i may get some thrashing for wanting to do this but if its going to mess my engine up or ruin the value of the car ill not do it. Just needing some input.


Thanks

Given the picture of the car, it's really not going to look right with something sticking out of the hood. There's a lot of newer supercharger technology that allows the blower to stay under the hood, but then the "looks" part kinda disappears. Not sure if Edlebrock has a kit for the small block, but you could ask.

And yes, if the car looks (or actually is) fully restored, cutting a hole in the hood would kill it's collector value. If you don't mind cutting the hood a simple tunnel ram would give a similar look, but the drivability will suffer - possibly a lot.

From a technical stand point, you'd have to know the compression ratio and figure out how to drive (under drive or over drive) the compressor. You'd also have to make sure you have enough room under the hood for the "extra parts".

That's sort of a 30,000' view of what you're getting into, and again, I wouldn't.

Welcome!

Welcome.
A belt driven through the hood, I gotta say no.
A proven belt driven under the hood, yes.
An OEM supercharger from the wreckers will take alot of fab and a whole lot of book learnin' to piece together a working package, I guess I'm saying no to this idea.

There are alot of ways to go fast and cool up the car without a blower.

Oh forgot, real cool car just the way it is.

I know beauty is in the eye of the beholder but that car is PERFECT!!!! Wheels, color, stance... Cool!



I would definitely give it some "go" power. If the block is still fresh, a low coast stroker would make great power. Wouldn't have much "bling" or "show" but she would be a runner.

Ok given that i couldnt put a blower under the hood without it ramming through the hood it will stay the way it is. Thanks for the imput though. Thanks for the good comebacks about the car i have had it in my possession for the past 15 years. I was once offered 14k for it never took it i told the guy no amount of money can by the kinda happiness i have for this car. Thanks again for the feedback.

But i am going to add this. Would it be worth it to add a good 4bbl intake and carb. Its got plenty of go power stock at the wheels for me to drive it....I can white smoke the tires from a stand still from 1-2-D. I have asked around and everyone says that a good 4bbl wouldnt be a bad idea. Oh and more thanks to go out for the welcomes im new to the forums. I have looked forever for a forum page with other gear heads. I just turned 20 so im kinda new to the whole engine freak scene. hehe. But any information will be helpful

If you put a blower on it ?? Find another hood/ or a fiberglass one./ Save the original !!!

Mr.4spd

It would be hard to beat a factory four barrel setup for your driving intentions.

We don't know if the engine is "stock" in relation to compression, cam, exhaust , etc. More importantly was it rebuilt as a restoration or a "hot rod"?

If the former, it's worth a lot more as is, but you can dress up the engine bay with an aluminum intake, 4V carb, valve covers, bright wires, etc, etc. It will take away from the factory look, but make the engine bay "pop".

If the latter, then the sky's the limit.

Just remember, for an engie to function properly, the "parts", like the carb, intake and exhaust manifolds, cam, torque converter (in an auto) and rear gears have to match.

Again, it's a beauty the way it is, so thing carefully. In my racing days (30 something years ago) I did a lot to my car, that now I wish I didn't - and yes, I still have the car...

Gorgeous car, reminds me of mine, just white instead of yellow.
A four barrel would do wonders on a 318, especially if it has a better than stock cam in it. stay away from original cast iron intakes and go with an aluminum one, I have a edelbrock air gap with a street demon carb in my barracuda and it performs excellent. being a 318 you dont want a large cfm carb either, nothing over 600, probably closer to 525. I'm running a 625 on my 340 and its a little over carburated. there's plenty of ways to "show" up and engine comparment, valve covers, air cleaner, chrome, chrome, and more chrome. some like chrome, some don't, i went with crinkle black mopar performance parts. if you still want it charged, look into a centrifical supercharger, like a turbo but belt driven, everything can stay under the hood and there is plently of shiny air ducts needed.

X-2 save all the original part's block trany hood ect. then build a monster, and in the future if and maybe when you need a sale an original is always worth more on the collectors market.
But remember what ever you do... the older that car get's the rarer it will become!

Cody_1992

Yeah its got a stock 2 barrel on it but every car that i have seen are 4 barrels i know theyre prolly aftermarket but i think it makes the engine look way better. No Engine wise. The whole engine has been rebuilt. Its got aftermarket pistons and the cylinders have been bored. Its got aftermarket heads with all new rockers valves and springs. The cam is aftermarket but it isnt a rough idle (I wish) its got the original single ported exhaust. the crank was fitted and fixed just for the car. Pretty much the only thing original is the block but its been bored. Im just wondering if a good 4 barrel carb and aluminum intake would suit it well. Im eventually going to add headers and a good exhaust to give it a good sound. its to quiet as it is. Keeping the originals in shrink wrap though.

Based on what you're describing, even with a mild cam, go for an aluminum intake and 4V carb. For what your doing a small Edelbrock (600 cfm or less) might be the best choice.

With a bigger cam and more aggressive head work (and a full header/exhaust), you can easily go to a larger cfm carb.

Basically what I did to my 318 decades ago.

Yeah i think thats what ill do is get a good Edelbrock aluminum intake and possibly a Holley carb. Maybe on down the road swap the cam for a good rough idle for the sound. Well i appreciate all of the advice and info if i have anymore noobish questions lol ill be sure to ask you Archer. Been a real big help.

A supercharger to NOT boost the engine is POINTLESS. Even for looks. A supercharger on the engine you have won't do much for you.

Carve up those exhaust manifolds, get a turbo, make your own plumbing, get a blow thru carb and 4 bbl intake, and slap some low compression pistons in and make some power out of that 318.

Or put a bigger engine in it.

If youre going to do "boost" it, do something different. And make it functional.



PS: It's your car. Do whatever. Cut it up. It's only metal. a 318 car will never be as much worth as a factory big block car.

I cut my fenders up. Didnt bother me a bit. I've also got a GTS hood that has a scoop molded on it. Didnt bother me. I know i'll be keeping my car forever.

a great candidate for turbos is a 70 charger they got that long nose allot of room for inter cooler my brother and i have already checked to see the possibilities of twin turbos under the hood would be a awesome mopar and would look and sound bad azz.

Procharger and Paxton make nice under the hood superchargers.. In fact Mr Norms GSS Demon had a Paxton. Mounts on the side of the motor and has a hat that the carb sits in. But.. it's a good idea to know how the motor was built and your compression ratio. I have a 273 4-barrel with bigger heads and adding a Procharger with 6psi.

Just remember the a used blower is the cheap part It's the rest of the setup that is $$$$
To fix it up nice as a driver ? Put a repo 340 cam a 4bbl intake and a small 4bbl carb

slade

anybody can make power with aforced induction setup. going naturally asperated is much cooler and.it doesnt take much to make power with a small block and there more fun than those slow revving bigblock. the first think u should do is find out the specs of the rebuild so we can help you were to go. and btw 4bbl carb and intake is always a good idea.

JayceDUSTER

Hey guys, sorry to jump in randomly but i can't find out how to post a new thread.

So i just rebuild my holley 4bbl and installed pertronix. My timing is all tuned in perfectly and my idle/mixture screws are good.

Problem: After about 1min of idle, the car will drop to about 4-500 RPM then slowly die off (Even if warm)

Also If i gas it mild-hard then let go, the car will have trouble picking back up and it will drop to very low rpm again and die almost instantly.

Any help please? Thanks alot. -Jayce

You Should start your own thread. Start by adjusting the mixture screws for highest idle. ? also check for vacuum leaks. You did re connect the vacuum advance ? Check the float level? Your tune up still needs work.
