I have the 302-3 pan. Somehow i managed to lose the spin on filter adapter. I have struck out so far today trying to find the Holley part number or its gm equivalent (assumed). I have found gm’s bbc’s and gen 3 LS but nothing on gen 4’s. I imagine the are the same as 3 but i cant prove it with a part number. Anyone know it?
Thanks

I't think it was a standard Oil filter stud piece. Not a standard GM thread?

LS1 and LS2 use PF46. LS3 uses PF48. They are different....

Got it today. Despite what the tech said they send GM part # 12600225. Holley # is 19R937.
