[soopertruper]

I'll be doing a motor swap over the coming weeks, and was wondering if I should do polyeurathane motor and the trans mounts. I run on the street and am looking to make 400+ hp. Thanks Damon

Yes, Those mounts will hold up longer than old style rubber. The mount that I would absolutlly change to ploy is the trans mount.
