Ok first off I know my heads are gunna kill my dyno numbers but its not in the budget at the moment so they have to wait awhile.

6.0l block 4.030 Diamond Pistons 10:1 comp.
6.125 eagle rod
4.000 scat crank
238/244 @.050 and .618/.609 Custom Grind
Ported as far as you can go 01 Ls1 heads,ls6 intake
3500 converter in a th400
12 bolt with 3.73 gear

Fuel System-Big Aeromotive pump(not sure what size,but its big enough)
injectors from 38-46 I have em all.
Stock rails,or I could get big ones no decision yet.

Any other info just ask,i have no clue on any kinda HP #...If I had to guess im thinking around 500 at the flywheel?I really dont know someone gimme a hint.

 

M6 I'm guessing?

I dunno have u had it tuned yet? Off the top of my head I'd say around 440RWHP and 415 RWTQ
thats if its tuned and running right

 

It says TH400. I think you'll put down around the 430-440 hp mark and about 460-470 tq. LS6 intake is a little small now days, and I assume only 1 3/4 headers. I suggest start by fixing those. Pretty soon the LS7 heads/intake will be availiable soon, but the valves will be too big for that bore. Don't know for sure, but there was something about indentical heads with smaller valve seats being availiable. Might want to look into that and save a little money by being a little patient. For starters, I'd get the QTP 1 7/8 HVMs with the dual cut-out y-pipe. That will help your power alot, and if you can, go bigger on the cam. You still have a little room for it with that stall and rear gear.

 

the headers are the QTP's, and I know the intake is small,i might use a fast or something like that..ANy suggestion on intake? And the heads will have bigger valves in them,i really would like to put AFR's on but I have to see whats in the budget.But if I can build a rock solid bottom end i will do the heads later thats much easier than the whole motor...Or since i grabbed this new block it might sit until i can get the heads,but that i dont know yet.
