11's n/a can be done. There are quite a few guys that have gotten consistant 12.5-12.6 with headers intake, CMCP deletes, under drives, driveshaft, gears and tires. You also need the proper suspension and a bit of lightening as well. Add the right combination of heads and cams and you should be knocking at the door of low 12's high 11's.
Yep 11.15 is my best, did it at 119 mph but the car has been [email protected] The most part of my power came from the 298 stroker and ported heads/comp cams. This engine made right at 400 HP to the tires through an automatic. The torque converter and gears also made a big difference. I was able to get 1.53-1.55 60 foot times to run 11.1's. The car weighed about 3400lbs with me in it. 3220 with out me. I could have gotten another 60 lbs out of it too. However this was before i added a roll cage. If I had gotten the C&L manifold on i think i could have gone 10's, even with the cage in the car. I wanted to do this but was offered a Edelbrock supercharger and new engine from my father...couldnt pass it up!
