The one time I ran my F body at the track since the last engine build, I ran 10.62 @ 127 mph on 10.5 nitto nt555r street slicks. I'm sure I could get much more out of it with a 4 link and some real slicks, but I'm afraid the numbers matching pontiac big block engine won't handle a super hard launch like that. It's not worth the risk of blowing the engine. The engine was conservatively built with edelbrock wide port high flow heads, a comp cams roller cam, 1.6:1 roller rockers, edelbrock single plane IM, Barry Grant 1030 carb (holly 4500 platform), .20 over 10:1 forged pistons, eagle rods and crank, long tube hooker headers with 3.5" collector, and dual 3.5" exhaust. At around 450Ci, the power is somewhere around 600whp on 93 octane. I copied the build of a guy who put down 700whp with the same setup. I don't have my timimg advanced nearly as far as he did, so I'm probably making about 10% less. It gets about 4 mpg, so It doesn't get driven much. Now that I think about it, I cant remember the last time if left the garage. Thats the problem with cars like that. It cost too much to drive them from day to day.
In my area there aren't many 4cyl cars that run 12's that I know of. I don't know many of the kids around here, so I don't really know what's out there. There's a few modded evo's, but no N/A 4 cylinder cars that run anywhere close to 12 sec.
