LOL, we know that's not exactly true Dennis!

But, the T10 you built for me and the restored factory Hurst shifter that I bought from you both performed flawlessly all weekend. Thank you!!

Here is a little coverage of the event. Bill Ketchum's Ambo wagon even gets a little feature!

As far as the stock iron intake and exhaust manifolds, they definitely are a restriction along with the 4300 carburetor. What I have learned is that the combination of an increase of compression and a small duration, wide lobe separation cam installed retarded really works well. 
We know that the limited induction simply does not support 390+ cubic inch over 5000 rpm, so I tried to maximize torque in the midrange.
I have custom Race Tec pistons to max out the 1.5 extra point compression rule for 11.7:1. I currently have the Lunati 256 cam with 213/220 duration and 112 LSA installed 4 degrees retarded. It idles super smooth and the high port velocity makes killer throttle response and torque. It dyno'd at 369 hp @ 4900, and 450 lb/ft at 3500. I also think the small Summit cam would be a good choice for this combo.
The T10 is a 2.43 ratio, rear axle is currently 3.73. The launch on the stock size Polyglas is tricky and takes a lot of practice. I try and hold 3000 rpm while staging, then slip the clutch and get rolling enough to feel the tires bite before fully releasing the clutch. An auto trans would sure be quicker, but I like the challenge of the T10. Shift at 5000, finish line is 5300-5500.

LOL, no huge secrets here! I've actually already spilled the beans on the combo back on page 3 of this thread. I'd love to see more AMC's get involved! All the rules are on the Pure Stock drags website:   www.psmcdr.com

Thanks for the repost and info. I must have missed it. I hope to set mine up like this when complete. That is one fine AMX you have there. Best of luck to you!
