I would be shocked if you weren't spinning really bad running with that much converter with stock suspension. Once you figure out the slide a links along with tire pressure and the 90/10's you will pick up a tenth or two in the 60'. I run the Comp 274XE, with the comp 1.52 magnum roller tipped rockers, MSD billet distributor. I was running a marine 4777 holley 650 dp that looked like it had set at the bottow of a pond for a decade or two.
