On other hand, don't think hydraulic lifters in an engine not set up for hydraulic would cause loos of oil pressure. I don't know where the engine came from or what it was in, and neither does the current owner.

Reason for question is another friend put hydraulic liters in his 235, did't run well, lots of noise, fnally discovered that it wasn't set up for hydraulic lifters, I understand some trucks didn't have hydraulics. Question, can someone tell me for sure if this engine is supposed to have hydraulic lifters? I looked up the engine number but all it says is '55 to '57 235 engine block. Told him I couldn't tune up his engine until we knew for sure we had an engine to tune up! So much valve noise hard to hear but think I can hear at least one rod knocking. I suspect either a bad oil pump or rod/main bearings worn out. I attempted to adjust them, but no response, felt like they are all flat, no oil in the lifters at all. He said the guy told him he had just installed a new set of hydraulic valve lifters. My '54 235 runs 50 to 55 pounds at 1,000 RPM even when warm. He told me a fellow gave it to him said, "It was running when I took it out of the car." I removed the valve cover, NO OIL coming to the valve train. It had tremendous valve train noise, so I asked him what he knew about the engine. Friend bought a '50 pickup with a newer 235 engine to me for a tuneup.
