If your going to swap motors then I agree with a smaller cam.

But just to clearify something, if you were building a 355 then why would you go with a smaller cam only to swap it later when you do heads. The 306/847 will CERTAINLY make allot more power with better heads, but I'd thrown that cam in with the rebuild. You kill a stock bottom end spinning it high, so if you have a good bottom end you're really not hurting anything. I've built a few with big cams/stock bottom ends ( AUTO TRANS w/CONVERTORS ) and setting the limiter at 6600 they run good and last.
