Top Swap with PLOG/3" Catted Downpipe. 100hp

Go read that thread that is linked to it...you take the top end of a GTP and put it on your GT and make 40-50 more HP because of the higher compression.

Probably 100 crank horsepower, who knows.

How you figure? If you go from MAYBE 170 FWHP with a stock L36 to 250+ FWHP with a TopSwap and supporting mods then that is around 100 crank horsepower. But I said around there. So it could be more, could be less...keep in mind your boosting a motor with higher compression than the L67 which is boosted from the factory and they run a low...what 8.5:1 comp. ratio? And make a solid 200 ish horsepower stock.

if you have a good running l67 it will put out 215 stock. those are the freaks that end up running 13s with an intake and a 3.4 with no knock. usually a full out cammed and intercooled car will break 300 to the wheels.

it really, really, REALLY depends on the tune though.
