cam for 505" stret stroker.

The 292 roller is on the big side for a 100% street car, but it is just about perfect for a street/strip type of car. I've used that cam in some 500 inch engines with good results.

EFI will help a whole bunch but you'll need some expert tuning help to dial it in. Once you have the engine up and running I'd suggest calling Rich at FAST Man EFI and having him help you with a remote tune. Typically you'll need to turn off closed loop and learn at idle and then set the idle AFR manually. You'll also need help getting the IAC settings correct for a big engine and the AE tables will probably need to be tweaked a bit.
