Tweet

just did a custom cam that was ls6 around 560 lift and 230@0.50 ground on a 110 and used the ls3 heads with 1.8 rocker comp rocker arm kit with comp lifter /spring kit #54200 was a LS6 stock bottom end and did fit runs very good in a 4 wheel drive hill climber /mud hole deal . i know the ls1 with a 1.72 rocker with the Trex.s cam will not fit in the a ls1 engine with stock piston with out work been there done that .but that engine i put comp solid roller on that Trexs cam and just tight lash it to .016 that was in a road coarse car it did get the hell beat out of it . the GM race hyd roller lifter can take alot of rpm if you set it up right would not be so fast in moving out of the hyd lifter cam go with sort valve lifter much the same as a solid... OH OK IF your taking about a BBC LS6 engine i do know about how much cam you can put in one with no piston work . i done many but what piston ? LS 6 piston gm or speed pro trw ? what heads do you have on it ? if the heads have not been cut much then i can get you close but GM never made a 10to1 ls6 so what do you have ?
