5.7 Hemi Stroker
On a stock short block 6.1, with street tires, I'd say the 7.37 is pretty good.
That being said, I wouldn't recommend spending the money on a supercharger without forged pistons.
On another note- you could leave the stock short block and swap on eagle heads. You end up with very high compression. There was a guy running 11.50's @118 with an 08-older 5.7 stock short block with GTP ported eagle heads at 4000 lb's.
