Mmm, if NOS counts, my motor would hold a blast or two of 150. A good launch at a real track and it should crack a high 10 okay . . . I think. I'd be deep into the 500s at the wheels. Cost. I dunno, $500-750.

This would be at the upper limits of the LS stock internals and I wouldn't want to do it all the time, but should hold okay and get me into the 10s.
For reference, at Satan's track, a.k.a. California Speedway, my best (and I'm an average drag driver) is
12.645@112. I put 391 to the wheels. This is a tiny bit faster than Sean's Pullied Cobra (

), the same configuration runs deep into the 11s at better tracks. This is all kinda guessing.
