I'll run it thru the program just for sh!ts. A guy over on another forum is running 10 O's with these heads. A 505 13:1 super vic, solid roller 310/318 274/282 421/421 on a 110 with valve events Intake 27,67 Exhaust 71,31. Figures its making 700+. Not sure how hard on parts that cam would be. So far, Dwayne's cam has made best power on my programs than any thing I have tried. Of the intakes he has tried, the super vic is the fastest on his combo and he had an Indy as well.
