If your going rockers...IMO, get the 1.95 Rollers...you will get the best gains from those...just figure if your going that route, might as well go all out. Springs; get Crow Cam 105's...no failure rate that I've seen. I'd still like to see how far you can go on the stock pulley...I bet a set of those rockers and a full custom tune might get you really close to 12's.

nice time, I would have expected a higher trap speed running mid 13's though?
He is on a stock pulley...its all in the first 1/2 of the quarter...these cars die in top end. Trapping basically 100 mph is something else on a stock pulley. I trapped 104 and ran 2 tenths faster than him with a 2.2 60 foot...see how that works? As for the Comp springs...that was a Mexico related issue...last I heard...the ones made in Mexico were the ones that failed. They changed companies again and haven't had any issues since. Hence why we recommened the Crow 105's vs. the Comp 105's.
