I run a very similar combo. It's a 408 magnum 10.0 :1 compr, .ported magnum eddies, ported M1, 950HP carb, 1 3/4 headers.My hyd. roller is an XFI lobe 236/242 with .579 lift on a 108. It gives me 10" of vacuum. It's run a best of 10.90@ 121 I have a lean condition with my fuel system so I'm expecting a little more out of it this year.
10.56 at 125.6, with a 1.43 60 ft.
E85, Hyd. Roller 410 magnum,full exhaust, 3500 race weight.
