Whipple, I just got off the phone with OliverJr at Jackson Racing before you made your post, they are a rotrex distributor. he recommended a 95mm pulley for my application. I gave him 6 in dia for the crank pulley and told him 6400 rev limit.
I really admire your knowledge and thank you for you help. This is why I joined this forum, great people, great minds.
Thanks,
Rock
