Version 1:
Big Block Chevy
6500-7000 Redline
4.290 Bore
4.25 Stroke
6.385 Rod
491 ci, I believe
10.4:1 CR

3946074 Aluminum Head
Flow at this cam's lift: 307 Int / 187 Exh
295 cc intake port
2.18 / 1.88 valves

Crane 134691 Cam
290/300 Adv. Dur 110 LSA .580/.600 lift
@ .050: 256/266
Here is the cam card:
http://www.cranecams.com/?show=brows...tType=camshaft

Rocker 1.7:1
Headers 2" / 3.5"
3" Dual exhaust with Ultraflow mufflers
RPM Air Gap - Rectangle port
Holley 850 CFM DP
cold air induction

Version 2:

All same, except the head:

Brodix Race Rite - Rect
intake 294 cc
flow: 332/217
valve: 2.25 / 1.88

If it is easy, I would also be interested to see if the AFR 305 is worth the extra time and Money:

AFR 305 - non-CNC
intake 305 cc
flow: 357 / 276
valve: 2.25 / 1.88

I really appreciate your generosity and willingness to share your time and knowlege.

Larry
here goes a try, new to forums, not sure if this is what I have to do to get the above info in a new post,,, but I am running pretty much the same set up 496 with the GM heads, little bigger cam and a dart intake

was wondering if this combo has been ran and possible pic or link to results
