I had to have mine rebuilt with another block after the first one turned loose. This one has forged pistons, roller converted with custom Comp cam and roller rockers on ported stock heads. Bassani headers, X-pipe with Flowmasters, Precision Industries 2800 stall and Mickey Thomson ET streets. It has MSD ignition and boost retard. Sheesh, I can't remember everything other than it has a lot that cost me a lot! You should see mid to maybe low 13's. Get it all together and prove me wrong with a high 12.
