6.0 with LS3 engine combination

If 10 cubic inches makes a 25 ft/lb difference, Everyone needs to .065 overbore their motor STAT lol.

10 cubic inches can easily be 10-15 lb/ft....

1.5 ft/lbs per inch is almost unheard of an old gas NA pushrod motor. If we were talking Honda K series motors I'd be more inclined to believe it. 2.5 is impossible.

I said 1-1.5...which is not unheard of for a LS engine...

546 out of a 6L, maybe...

We're splitting hairs here...the fact is 1 lb/ft per cubic inch is easy...that's a mild engine. Stock...my 6.2L makes 390 torque at the rear wheels...and it's a ***** cat...

1 ft/lb per inch is easy, but 390 at the wheels is still only 460-475 at the brake. 520+ is impressive.

One thing is for sure. modern motors are making stupid power for cheap.

For a "budget" street built, the GMPP CNC LS3 head is the only way to go. Less than $1400 for a set of heads that flow more than 350 cfm at 600 lift, a better deal does not exist.

Also GM says you're wrong about low end torque comment.

The fact that you tried to make a point by comparing torque on a 6.2L and a 6.0 with different intakes and cam's is a little scary... I'm done....
