williamb82 said:thats not the oil pressure i have, its what i read was acceptable in either the chiltons or the haynes(dont remebr which at the moment). i just want to make sure when i build my other motor that it will be trouble free for at least a year or 2. i have a lead foot and drive the car very hard day in and day out. you can ask eric, paul, or dave, they will tell you. lol. anyhow, since im about to put the short block in my 84 i will try the shim mod to the oil pump. btw, ,anyone know where i can get a 5m pump cheap. i found one on toyotaparts.com and it was like ~$175. id rather not go broke on a oil pump for this block. i will definatly go oem for the race motor though.
William,to quote the Godfather of the SBC "Smokey Unick "sp"",any engine needs only 5-7psi of oil pressure per 1000rpm.At idle,many of my old Mopars ran 3-5 psi,and all the manuals of the day called this acceptable,never lost a motor that was not my fault :twisted:
As for your oil pump,I can supply a factory 5m pump ,shipped to your house,for aprox. the same as the one you found on toyota parts.com.They come in an afermarket box,and the the "toyota" is ground off the housing.I just priced them this week,$165 + shipping is what I can sell them for and not have the boss nibbling on my behind
