question on phenolic spacers

Haven't used spacers on a Mopar SB. But have when I was building SB Chevy's (sorry guys & gals :geek:) more for strip oriented than street builds. Typically I found low end power to dip a bit, but picked it up on the top end. But on a strong running motor I found the low end losses negligible. Being a very simply mod, you may just want to give it a try and see how it works for your application.
