Need help with some cams
I bought the stage 3 Comp Cams for my 4.6 Bird and was reading last mo. Muscle Mustang and Fast Fords magazine where the were testing the cams and the last cam was the Big Dog cam. On there it said they recommend valve reliefs, the cam info: .545 Intake and .545 Exhaust, duration @50 242 intake and 246 exhaust. These cams are going in the Windsor PI heads that will have a 5 angle valve job Port and polish with bowl work. What do you all think? Can I use the Stock block or do I need to get new pistons. I pretty much have everything already, what do you all think i'll hit in the 1/4mile? Im planning to forge the bottom end or just buy a 5.0 stroker kit and supercharge it with a vortech!!!
