Twin Turbo 350

The Muncie wont last long either....

Turbos make big power wasy, A trans needs to be pretty stout!
On my current lowest possible boost setting at 10 psi, my 3,800lb car still went 130 mph through the traps at the 1/4 mile dragstrip! That has gotta be about 700 hp at the crank. On "low" boost.

What are you going to do with the car? drag? Road race? show?

My poor muncie . I guess I should plunk down some money for a tremec.

What I really want is a nice driver that I can enjoy and have the cool factor under the hood. The car already has the upgraded front suspension and brakes. Now I'm looking to do the body work and start planning the powerplant.

I've built plenty of fast small and big block motors, I wan't something different with this car. Smooth AND fast. The pro touring cars I have seen on this site and others are just amazing and I'd like to go that direction.

Here's what the car looks like now:

That's awesome. I had a '68 SS 396 Chevelle, I wish I still had that one.

I just started looking at turbo setups over the last couple of weeks and I can't believe the power they create. I'm half tempted to turbo my F-150 too.

Just figured I would try and give you a little more insight into the requirements for your twin turbo project. The engine components that you select need to coincide with the H.P. and boost levels that you are trying to achieve. If you are planning on making more than 600 H.P. wich is very easy to do with the right set-up you should consider all forged internals as well as an aftermarket block. I am not saying this is a must do, it just depends on how much you like to push the envelope. You can easily make over 1000 H.P. with a blow through carb set up running around 20lbs of boost with twin 66 mm extended tip turbos. To do this you should also consider running at least a good set of MLS head gaskets and ARP head studs. If you are going to try and run more than 25-30 PSI of boost you will need to o-ring your block and heads and run copper head gaskets. Weather you go with a carb set-up or EFI you will need to upgrade your fuel pump and have a boost refferenced regulator. It is very important that you add 1 lb. of fuel pressure for every lb. of boost. You also may want to consider running an intercooler preferrably an air to water because it is much more efficient and you can fit it in a very small area. You can do an air to air a little bit easier it just depends again on your ultimate goal. You can go in the sponsor news area of this forum and see pics of our TT kit under the heading new tt kit . I will be posting more pics of the twin air to water intercoolers that I developed for my 69 camaro they are pretty trick. I hope some of this info helps.

If you plan to make some big HP #'s, check out my post in for sale. I'm letting loose of my Bowtie block sbc built for big boost.

Honestly, I think 600 horse ought to be plenty.

That will be a piece of cake with turbos.

Just build whatever fits your financial budget and horsepower desires. Turbos will make alot of HP even with a small cube motor. 350 = about as cheap as you can get from an aftermarket parts perspective. You can use a blow thru carb instead of going FI and will save you lots of money as well.
