LQ4 bottom end, LS3(l92 with diff valves) cylinder heads/intake/injectors, Edelbrock 90mm Throttle Body(DBC), Patriot extreme springs, EPS 222/230 on 112, lift .600ish.
Don't put a cam designed for a cathedral port head(ls6) in an engine with square port heads(L92). You need to look into a torque cam designed to work with square port heads (L92/LS3). Without dyno number I won't comment on the torque numbers but 10% loss seems pretty high. I think either intake will be fine but the truck intake has longer runners IRRC. Better get the cam right, none of the rest of the parts will matter if you don't get that part correct.
Intake info to look at, basically says it doesn't matter L92 vs LS3.
You'll find people out there with much more knowledge than me on this, I only know what I've read and what I've scanned on my own.
