Fantastic times for a cam only. Congrats.

I'm curious about what you stalled up to for your launch and also your cam details.

Very impressive times especially at 3500lbs

Thanks everyone, been a long time coming.

Left anywhere form idle to stalling it to 2,500.

Seemed to work best just stalling it up to about 1,500 rpms. Tired idle and stalling the **** out of it, no real difference in 60'ft/times

max timing is at 29* reg pump 93.

have not data logged it at the track yet, just on dyno. Need to datalog it and raise shift point higher for sure. made 397 on a MD dyno.

Have it shifting at 6,700 so far, seems to be close to that at the trap. Has a 26" Hoosier drag radial w/18 psi and 3.89 gears.

Cam is a custom cam by jarrett faggart. 233/236 hav to find other specs. Spec'ed it when my car was still a DD, mas effort DD drive ability cam.

Have a 8 pt cage on order. Local track is cracking down on safety, so that is the next mod since a 6 pt roll bar is only good for a 6.50/10.00.

Hum... interesting your running 29*. Since it was dyno tuned, I'm taking it made the most power at 29 then. I never had my car on the dyno, I have 28 in mine as a BOLT ON car and every time I would try 29 I would immediately get 1* of knock. I always wondered what my car would do on lower timing that maybe 28 was a little to much for it and made the torque start falling back off by overshooting the timing.
