Hey, I'm new here and to nailheads, but I am an old car guy. I have a 1957 Special 250hp engine with 1961-66 heads. And an Offy 3557 triple intake. What year head gaskets do I use? Aside from port matching, is there anything else I should do or know?
I've searched for this part number forever. I want to replace the oil pump in my 1957 Special 364. I am reading I should replace it with a 1959 oil pump but cannot find the GM OEM part number. Just can't afford to buy the wrong one. Please advise.
