My upcoming heads/cam setup and install
Here is what is going on the car:
TEA stage 1.5 5.3L heads, milled .006"
Cometic .045" thick gaskets for compression of right about 11:1
F13 cam 112 LSA, +4 degrees advance
new comp 850 OE replacement lifters
7.4" pushrods (closest I can get with big money for exact length pushrods)
Reuse stock rocker arms
ASP underdrive pulley
28.8 lb injectors (GM)
new oil pump (LS6)
new LS2 timing chain
ported TB by me
I think thats the major stuff. I want new plugs, but can't decide if the NGK TR55 or TR6 would be best. Any opinions?
Mods already on the car:
BGRA, Jet Hot LT and ORY, lid, ported LS6 intake, QTEC, HP tuners basically stuff in sig
Any opinions/thoughts/hp guesses welcome. I am shooting for 440-450 rwhp and 425 rwtq.
