What was the original cam you had in the car when you made 457rwhp. Looking good. I'm finally getting around to dialing in my 347 and I'm trying to collect some camshaft info. I don't think I'll get numbers like that, because I'm simply not willing to rev it that high.

It was an AFM N91 cam. Why don't you want to rev it high?
If I had a 347 I would look at a XE282 with possibly a set of 1.7RRs. I think that would be a nice cam. Or maybe a VooDoo stick.
Also have you talked to Cam Motion Home Page ? They are some good guys and if you give them a starting point they might could cut you a nice cam.
