Car Craft Little Bro 5.3
I just got my October issue of Car Craft and in it they take a stock 5.3, add a set of long tubes and swap in a LPE GT2-3 and GT1-1 cams and made nice power.
stock w/ LTs: 323hp@ 5400, 355tq@ 4000
GT2-3: 378hp @ 6000, 366tq @ 4800
GT1-1: 413hp @ 6600, 369tq @ 4800
cam specs:
GT2-3: 206/221 .571/.578 118.5 lsa
GT1-1: 229/242 .631/.631 114.5 lsa
next month they are adding heads and intake.
