Anything you would do differently please let me know.

Holley stealth ram
cc306 = 230/244 and .544 .576 w/ 1.6rr
proline heads = 200cc
on a sturdy bottom end.
(I'd go into detail but there's not a whole lot a difference between one 355 to another)
I'm looking at 10.5:1 compression.

With the old setup she put out 267 rwhp and 356 rwtq. I'm trying to find out what numbers I'm looking at w/ the new crap. Please assume that the car will be dyno tuned and that there will b adequate spark and fuel.

Any suggestions, replies, questions, comments, or theoretical dyno numbers are greatly appreciated.

I have just gotten my engine running it is somewhat similar to yours. You just have a bigger cam. I went with a comp extreme energy cam 224/230 .536/.544 112, but we have the same heads. Hope to have it on a dyno in 2-3 weeks. JMatlock88 made 380rwhp with a stealth ram 350. I think he was running a 224/224 cam with AFR heads.

Very similar to mine. Just ran 12.895 @ 108.15. The mph would indicate 320+ rwhp. There's more in this combo & I'm still tuning.
