I promise I will quit asking so many damn questions one of these days guys. I need to re-cam the motor that I will be putting in the 21' Daytona and I would appreciate a little help with selecting the right one. The motor is a 522ci BBC 9.8:1 compression with AFR CNC'd 335cc Aluminum heads, Dart tunnel ram, two Holley 750 DPs, MSD ignition system. The boat is a Kevlar lay up 21' Daytona with a full interior. I have a stainless 9.5" impeller as well as a stainless "B" cut impeller.Pump has an inducer as well. I imagine I will be using the B impeller. I was thinking about using one of the Isky jetboat roller cams that is .640"int .650"ext. duration @ 50 is 264 int. 272 ext. 112 center. What do you guys think? This boat will spend a lot of time at cruising speed with the occasional WOT here and there and I will probably put a small shot (150hp)of nitrous on it too. Any help would be appreciated.
