I don't have as much time to be on the boards as I used to. I can't follow every post made about one of my camshafts.
Dana S60's are heart breakers. The fact that it dropped from 440 to 405 is enough to show that as true when he first installed it.
So we take 15rwhp out of the numbers for SAE and smoothing. Then multiply .08% x 485 and we get 38. 485+38=523rwhp/469rwtq
What am I missing here from a 10.8:1 376 short block? That's 50 numbers behind the person's 427 who said he wasn't impressed by a 10.8:1 376. Might I mention that 427 has an even larger bore which further un shrouds the massive intake valve that a LS3 head has to begin with. This is just what a LS3 head needs to show it's true potential which his set-up certainly showcases the potential of a LS3 set-up.
I think the fact that a no torque making LS3 head can make 400rwtq at 3600rpm with a big cam is pretty good if you ask me.

if there has been no design changes...them spiral flow mufflers are junk. they sound good but, for power no good. I used them 12 or so years back to try to quiet the car down...big horse power robbers
