A l31 would kill the power of that engine.
Cam size dont mean a damn thing if you dont have the right stuff to back it up.

A 383 with a C306 won't need to be spun past 6500 even with ported heads. That cam just isn't big enough for a stroker to keep making power past there. Assuming your bottom end has ARP bolts with Clevite bearings and was well balanced, it'll hold to at least 7500 on a road course, 8000 drag racing.
