I run 11.6:1 compression with 93 octane gas and its fine so 11:1 on 91 craptane is more than ok.

My AFRs were only milled to 63cc in case I wanted to upgrade to a bigger cam. (I have the 224/228@114) Car still pulls like a solid freight train!

Has anyone heard of any stock engines with fly cut pistons letting go?

I know someone that has done this running AFRs andt I'm thinking about doing the same thing.

There are two cars in AZ with this set up running much larger cams one was at 487rwhp and the other at 490rwhp

Anyone care to take a guess at what hp and tq I will be at on the dyno?

2000 M6
LS6 Intake Manifold
Powerbond crank pulley
AFR 205 heads (Lets say 66cc, Out of the box)
224/224 581 581 114LSA +4 Comp Cam XER Lobes
LG pro long tubes w/hi flow cats
B&B Bullets
K&N Intake with airbridge
Stock Throttle Body

I know, I get tired of people asking this stupid question too, but Im just excited and curious to see what everyone thinks. AFR Heads and cam get installed in 2 weeks.

Good luck and my guess is somewhere in my ball park (420/390). You have a bigger cam and M6 and I have the FAST with LS2 TB

Im just looking to be over 400whp and I will be happy, for awhile. I think your about right with your guess though. I would be really happy with those numbers.

Some people can never get enough power even though they cannot get in to ground. I find that this RWHP range provides more than enough power.........

I'm currently running AFR 205's milled to 61 cc, .040 gasket, a cam that's a little larger than an X3. All on 91 octane. No problem

I put down 483 rwhp and love the power.
