i have an 87 1/2 ton with a 305TBI set up in it. i just swapped in a 350 from a wrecked 84 sub. during the swap i dented the oil pan on the 350 so i thought that i would swap it from the 305. during the process i found out that the 350 is a 4 bolt (oh yeah) and i also found out that the end caps are different on both engines. on the 305 i used a 1 peice rubber gasket and loved it. when i replaced the gasket on the 350, it was 4 peices and it is leaking now. my question is, is there a company that anyone knows about that makes a 1 peice rubber gasket for the 84 350??? any help would be great. please help!!! this weekend is the best wheeling weekend in NJ and i don't want to be down because of an oil leak.
