Hey while we're talking oil pressure in 235's, mine is a '55 fresh rebuild, I was reading 45psi when cruising and around 25 on a idle. This is with an after market S&W guages. Just last week after putting 500 miles on it, it pegs the oil guage at 60. I've obviously checked the oil and everything looks fine, did I loose a sending unit? I drops to 0 when I shut it down.
