Whoah... What was your main and rod journal clearances? What weight oil, what oil pump?
Excessively high oil pressure could mean too-tight bearings, or sticking oil pump relief valve, or blocked oil passage in block. What is the pressure when hot? Are the valves getting oil? Is the motor overheating at all for no good reason? Any metal in drained oil?
I once had 60-70 psi in a fresh '54 full pressure shim-style 235. The mains were shimmed too tight, it ran for 300 miles then went BOOM. Started overheating and making noises. Oil pressure went from great to in the basement. Bearing material came out with drained oil in ribbons. Check for metal in oil.
chip, the master of 235 disaster.
Edit- BTW, the '60 235 discussed in above thread is still running. It has 45 PSI when cold, 28 psi at idle hot, 35 going down road.
