looks like good parts for sombody thats building a 50s hot rod

I wonder what kind of blower and carbs you could put on it?

I recently saw a picture of a 235 adapted for a 256 supercharger to run at the salt flats. But that guy built a custom tubular intake.

But I wonder if the engine can take much boost in its original condition. I know compression is low enough, but are the pistons up to the task?

I often thought it would be fairly simple to turbocharge a stovebolt with a little Garrett T03 and use low boost, like maybe 6 psi, but that question causes hesitation from trying it as an experiment.

Last weekend on "Two Guys Garage" they had a show on forced induction. Instead of showing us each different type on a bench they showed them on vehicles.

One was a t bucket with a supercharged straight 6 and another was a turbocharged straight 6.

Then they installed a turbo system on a newer camaro with an LS1. It was quite different in that the turbo was at the end of the exhaust under the rear bumper.

if i could get any help form the guys over at inliners :rolleyes: i am trying to drop the 235 from my truck into a 77 nova i got for $500. i will be fabricating a turbo setup with a t04 turbo, so i guess we will se what she will take.

anybody have any ideas on the limit? i was goin to run the turbo at around 8 psi.

You will want to run some intercooling if you are going to push more than about 6 psi into a 235. The combustion chamber is kind of a funny shape and doesn't handle a high intake charge temperature too well. You may also need to reinforce the head gasket with an o-ring setup.

I would use a 261 head (casting number 3836850) on a 235 since it has 0.5 lower compression, and put in hardened valve seats and stellite valves. I would use the big bypass thermostat from a 261 and drill the steam holes in the block from the head. 261's have additional holes between the block and head to cool the head better, since the cylinder walls are siamesed.

Convert the block to full flow oiling and add a good ignition system and you should make decent power even with a stock cam.

I did some calculations and research a while ago and I figured I could do about 225 horsepower with my 261 and a supercharger with about 6 lbs of boost and have it still live long. That would be fun street power without worrying about it blowing up.

Forgive me for not knowing, but what are the OEM 235 pistons made from? Cast aluminum? Are they suitable for low levels of boost, i.e. under 6 psi?
