Really? Didnt figure it'd hit that high in the numbers with the 64cc 243's. If $ is right i want a set of 2.5sg 5.3's .Bet she'd really come to life with a 150 wet shot anyone else running or know of anyone with a similar set up

400whp give or take, Port the 243's and you will make 440 or so. We can port your set if intereste. 469-556-4580 Thompson Motorsports

With all supporting mods in place and tune spot on you should be around 420 at the wheels

Thats good #'s how much would a set of fully worked 5.3's pick the numbers up over the ported 243's? Id like to be in the range of 450hp if possible w/o throwing to much $ at it.tryin to keep the bill down as much as possible gotta have tranny gone thru also to get ol' besty back rite n on the road.

ported heads with the ms3 and lq4 440-460whp depends on how its breathing on the intake and exh surrounding the build.

Wouldn't the 5.3's help more on tq than the 243's ? Want more of a bottom end than i had with the stock ls1. Car was dead until about 2300the rpms then sprung to life
