I am new to the boards, and have a ton of questions. I will make this as painless as possible. I own a 1980 Pontiac Lemans that currently has a Pontiac 265 in it. I just had a 1974 Catalina 400 Rebuilt and getting ready to do an eninge swap. I have never done anything like this before, and would like any input I may get! I can't find headers, which seems to be pretty normal. Didn't know if there was any update on headers for a G body with a pontiac 400 in it. Also didn't know what I needed to get for motor mounts. Again, if anyone had ANY inoformation, it would be greatly appreciated!
