Background info for those that do not remember or not know:
My son has a 1946 2 ton truck with a 235 that he uses for his catering business. He has a wood burning pizza oven on it. His original engine dropped a valve and needed a rebuild.
At the same time I got a generous gift of a 1954 235. We decided to have 1954 one rebuilt and put into his truck.
Then engine just got back from the rebuilder and the repair shop is in the process of putting the engine back in the truck. This is when I got the call that the exhaust manifold was over .030" warped and the metal looked to thin to send out to have it machined.
This has started my search to find an exhaust manifold.
I found a 58 235 engine that appears clean, low mileage, well kept. I have been told that 58 manifold will fit.
Told my son about this engine and his concern is what are the odds that this manifold maybe bad. So what are the chances I would be wasting my money on that old engine.
My son has been tow baring his truck to his catering events for a while and wants to get his truck under it's own again soon as possible.
So I mentioned that they make Fenton cast iron dual headers.
I told him the advantages are that they will fit and work right out of the box so he would get his truck back on the road faster.
I said the headers should not impact performance or MPG much because the intake and exhaust are still stock. Am I right on this assumption?
Will there be a drivability issues using the Fenton headers?
Any other potential problems you guy's can clue me in own that I have missed?
Thanks Jeffrey.
