I recently installed a newly overhauled 235 engine into my '62 C10 Stepside. The SN's are only about 100 # apart. Anyway, here's what I did during the overhaul and subsequent installation: Took a '62 era 235 block, bored it .080 over, installed a "261" cam, "848" cylinder head, with Fenton Headers, an Offenhauser 2-2bbl intake, 2 Carter/Weber 2bbl carbs, and finally, a HEI ignition system.
We also fitted the block with the flow through oiling system using 1/4 steel line and a remote, spin-on oil filter. The engine starts and runs fine and I am delighted with the tractability of the entire setup. Here's my question: upon start, the oil pressure quickly comes off the peg and climbs to about 25 psi. From there, it rarely wavers; at least at idle. When the engine is fully warmed, the pressure drops to about 20 psi and stays there regardless of engine speed. Should I be concerned with the lack of fluctuation? Is the system working correctly? Your thoughts?
