Re: ls6 cam
The Crane unit is a true "blueprint" cam, which is probably why GM offers it...the others just try to get close, but they're all over the map. Been there, done that...
As for your future combo, our Y-Camaro is 12:1 with the 143, but 840s instead of 074s...and it's putting 430+ horsepower to the rear wheels, through stock exhaust manifolds in Pure Stock form...so decent power, I guess...
