Camelback Posted November 16, 2007 Share Posted November 16, 2007 If it was me i would put a 350 turbo on it and she will run like a scalded dog. I have the part number to one if you would like. schiweizer is what i would go with instead of the air reasearches.

Kav Posted November 16, 2007 Share Posted November 16, 2007 Had the ol 237 tweaked a little-any merit to installing a bigger turbo?-KevinHi Kevin- In the past we used to run the 237 motors with the pump set up exactly as a 285 and we put the 300/350 turbo on them. You must fit a bigger Air cleaner to the truck the same as the E9 V8, as the original cleaner is too small as it builds up a vacuum going up a hill even at 237 with a new element. An air scoop on top of the Air cleaner also makes a difference. It is a good idea to fit a turbo boost gage as the boost can go up to 35 psi when you first start the truck on a frosty morning. You have to drive them by the Pyrometer as the exhaust temperature will go up on a big hill, so you just have to change gears a bit sooner to stop the Pyro going too high as you dont have any intercooling. We had that system on three different trucks and they all worked very well. We used to have some trouble with the early 1970's type Maxidyne Pistons but when they changed to the Econodyne type with the top inserts, we did not have any more piston failures. The old ones used to fail occasionally even with a standard 237. If you have a reliable driver you wont have any trouble. I still have one truck set up like this and another one that I used to own is also still working every day.
