OK.. So to me the most telling statement was "and it hadn't even really been tuned yet".

You're out screwing around at 8k on the street in an un-tuned motor. Hate to say it but you were asking for it. Hope that $20k dent in your wallet doesn't hurt too much.

Sorry guys but the motor was only driven a little untuned. No wot just home from the shoppe. And it wasn't untuned in that respect, it had a base table from a 383 LT1 forum member who was generous enough to share his Accel dfi tables with me. When I did get the wideband in the tables were'nt far off from what they needed to be.

8000 rpm + beehives = a sound that is beautiful

it also = 128.7 mph in the quarter mile the way it is driven every day with a 19' street tire, the stiffest suspension possible and slammed to the ground with a heavy sound system and full tank of gas. this thing is the farthest from a drag car that is possible. So to me that is impressive.

a bad valve job with a loose rocker nut.. possibly = boom.

Anyhow the only info/update Slalom i posted in another post above. I feel kinda dumb having 2 posts going but I pulled a plug and saw some dmg.

How did you end up running a solid roller with beehives? What the heck kinda beehives were they?
I've done plenty of solid roller motors, and they all take duals with dampers.
