first i'd like to say im glad i found this place , ive looked around the net for a while trying to find a good place to exchange information on hot rod chevy motors ,and never really found a good home, ive been building this motor for a few months now and im just about ready to fire her up, built the whole thing from scratch,its been an expereance , and im sure my wife is about to divorce me ,
anyway i talked to melling tech today ,and read a bunch last nite and came to the conclusion that i can use the m55 or the newer
10552 w/10% more volume , my part houses only have the m55 in stock and at 13.00 im going to put that in and try it , if the oil presure is on the low side at idle i'lll switch over to the 10552 +10% unit, yes i have the stock oil pan
