Default Big cam 346 power?

I am putting a huge cam in my 346. It is a 242/246 .621/.614 111LSA 109ICL.

The heads are 2.5 5.3 prc heads that are going to be milled .040. The SCR is going to be around 12.2:1 and the DCR will be 8.8:1. The bottom end will be completely freshened as well.

What type of power should this put down?

less, like maybe 450. But, that is the way I think. Therefore, if it makes more than I was thinking, I will be very surprised! I like surprises!

440......

MellowYellow has a RPM6.... 244/248 in a 346 with 10bolt and makes 440ish..... optimal setup with waterpump, pulley, and good exhaust thru a T56 might make 470ish.

ahh I think it might make more than that. add a fast 90/90 setup and he could very well be in the 485 region.

try to get a fast 90/90 on there and if you have the money get it ported as well that should put you higher in the hp/tq range.....

depending on what you hit w/ the prc's i may be inclined to try them....rite now im infatuated w/ the tfs 215s and the afr 205s

when will you be done and on the dyno?

rite now id say around 460ish
