Working on a 521 build with scj heads. What kind of profile of solid flat tappet cam would work good with this. Like to make as much power as possible. Would it be possible to have a cam that makes big power and not have to turn rpm up real high.

Intended use, gearing, trans, vehicle type, weight etc etc will all have bearing on proper cam design... More information would be helpful.

i got a 521 with SCJ-A heads with a solid flat tappet and i make 509hp RWHP at 5900rpms and 521TQ RW at 4600 rpms. don't know if this is what you cal real high rpms or not. (note those numbers is to the ground and not the flywheel)

Call Scotty J at RHP (aka the mad porter) for details!!!:D

Unless you are after every last 10th get a C6... Especially true given your vehicle weight...
