Have patriot springs, ls2 timing set, ls7 lifters, ls6 ported oil pump, stock 243's which may get ported depending on funds, fast intake with 102 tb, new kooks headers.

I have yet to decide on what size fuel injectors, what route i want to run my exhaust, if 243's are the heads i want to run, and what stall convertor?

that cam is pretty common..spike offers that cam alot...is it 111 lsa??

i have a lq4 i hit 12.3 @108

799 mildly ported heads
built 4l60e
4k pi multidisc
4.11 gears and tru trac
nnbs intake with 90mm edelbrock tb
headers minus the pulley
i ran a tsp cam..233 239 595 603 112 lsa

You don’t need to go too far out of your way to obtain 400rwhp out of a 6.0L. I know just about everyone is already acquainted with what Wheatley’s truck laid down with a pretty basic combination. Hell, beings you already have the FAST intake covered, you already have one of the larger expenses out of the way.

6.0 LQ4, stock bottom end
Stock 243 heads, milled 0.035”
Kooks 1-3/4” x 1-7/8” stepped headers
Comp 228/232 588/595 112
Fast LSXRT-102 intake manifold with LS3 90mm TB
Performabuilt Level 2,PI 36-3800 triple disk and 4.10's

Factory Truck Manifold
SAE
392.77 RWHP
391.61 RWTQ

Fast LSXRT 102mm
SAE
423.03 RWHP
410.01 RWTQ

sorry i do recall seeing that forum but never finished reading it. Should i throw a nick williams 102mm tb with the fast or would it not be much of a upgrade compared to the 90 mm i have? also i'm actually thinking of buying the tsp 2.5 ls6 heads, but if that don't happen its going to my transmission funds.
