Thanks for all the info. The engine has castrol 10w30 with a can of Lucas oil additive in it now. I bypassed the oil filter and the pressure came up about 5 lbs. cold. Didnt have time for a drive to warm it up. They had a nice show on horsepower about rebuilding a 235 today but I missed what the used for oil pump.Think I will pull the pan soon and see what it looks like in there. Thanks again for info
