Cat-n-Around

Changed cam and heads looking for a little help on pulley selection. Went from a stock 502 cam and heads to a rmbuilder cam and Dart pro-1's by Jim Valacko no porting. My original set up with 871's and twin 750's was 33 on top and a 31 on bottom (6% under) with 6 lbs of boost. at 5400 rpm. I want to run 6 to 7 lbs at 5800 what pulley set up do I need???????????????

Cam specs: @ 231/239 and .598/.617 on 114

Thanks for the help.

I think you'll be close with the pullys you have,. if anything you might need to drive it a little harder...IE: 4-5% under
