Chevy Small Block in my 301 T/A?
 

I'm putting a Small block Chevy 400 in my 81 T/A that had a non turbo 301 in it. I'm using motor mounts from a similar year Camaro but they don't seem to fit. I moved the mounts to the holes that seemed like they would be the right ones. Anybody know what I'm doing wrong here? Do I have to drill new holes?

need to use malibu frame mounts, not camaro. holes are not right.
