"Stealth" Cam / Heads? OK - I know I should be happy with the power I'm getting now with the minor mods so far BUT...I WANT MORE!!
I don't really want to try to win the "rumpty rump" idle award, but I would like more goose in the BlueFlyingGoat. So I have a few questions:
1. Has anyone tried or are currently running either the CheatR cam / heads setup from Thunder Racing or the SI007 cam from Speed Inc.? Or something else similar you've run or would recommend? If so, how do you like them and how much RWHP/RWTQ did they make for you?
2. If you're going with a "stealth" setup, is there really any advantage to changing the heads? I can definately see changing the valve springs and the pushrods just to get some additional RPM, but I'm not sure how much of a difference adding the heads to the mix will make.
3. OR...should I just stay put until I can do a forged motor? Or forced induction? Or bag the whole thing and go N20?
The polls are open...will check back tomorrow PM...

411 rwhp with CheaTR cam, AFR 205 heads, FAST intake and stock exhaust manifolds, stock cats and SLP Dual Dual catback. Very stealthy. Sounded stock, cleaned some clocks.

388 rwhp with the CheaTR, Patriot Heads, and the LS6 intake w EGR through stock manifolds and cats. In my area they are pulling people over for illegal mods so I chose to go "stealth". Im happy with my choice. Just wait until I hit it with the 150 wet shot...........
Edit: This is through a 12-bolt rear, so it probably cost me a few HP.

While we're waiting, got a link to the MTI cam specs?

I was over at Speed Inc. today and let them talk me out of the SI13 (224/224) and into the SI007 which will be installed begining of August.
So I'll pose the question again since it's been 4 months since the last
reply. Anyone using the SI007 ?
thanks

If retaining stock heads, then:
Search under ragtop and view the thread of "max overlap with stock manifolds" excellent cam selection there.
Or if use headers then Old Man Cam from TR.
