Default first #'s with BRE cam 383

I see a lot of people getting on the dyno lately..so I'll tell you my dyno story.
My car had an rpm miss from 5k-6k a few weeks back on the dyno, so I just put in an MSD 6AL ignition and replaced a wire to the battery that flaked out right after the dyno. It has an entirely new ignition system..plugs, wires, opti, MSD, coil, etc.
Anyway, with the miss, it made 376 rwhp@4800 rpms, close on torque..when I get it back on the dyno soon I'll post up the dyno graph.
I'm hoping for over 400 rwhp, because it's probably close to the biggest hydraulic lt1 cam you can run. I'll post up the results soon.

Sounds like you sould peak ~6500-6800rpm, somewhere inthat ballpark. You definitely have alot more in it... probably another 50rwhp...

He just returned from a few days in FL. R&R (Rest & Recovery) now, I'd guess.

With a 3150 raceweight and the parts listed, you've got a 10 second player for sure. What type AI heads do you have and what's your CR?

Yep, big *** cam on a 108 lsa, 4200 stall. It sounds like Mr Redneck is starting to get serious.
