The heads are just GM LT4 head & intake castings ported by Pete Incado @ CNC Cylinder Heads, down in Florida. Nothing special, just his normal deal. Wish you could put big valves in them. Kinda looking at some other options right now.

What rpm are you turning? And is this on pump or race gas.

Wanna bet? Ask Jeff Moore, (Z284thgen) he is from Tulsa, and has seen the car, and watched run all summer. Jeff & I also have the same size cam. I shift it @ 7200. Stall it to 2000 (foot brake) & stand it on the bumper when it leaves. Plenty of local guys come by the shop, have seen it apart, watched it, raced it, etc.
Jeff, tell him. <BG> It ran 10.26, 10.28, 10.30, over 131 mph, etc right down the road from you, at Hallsville TX. Found I had too much gear in it after the Tulsa track closed. Tested down there with the new gears. Air never was killer, best I got to run in was 600'. Picture of it on Hallsville's website. Bottom row, to the right right. It gets a lot higher than that picture. <G>
Take care, Ed

I've seen his car many times at his shop, heck I've even seen them when they were off the car. The car flat out flies! This gives a little more respect to the LT4 Castings for sure. Just need to paint a big red "S" on the hood and call him "SuperMan", because when he takes off it's kind of like that.

the high rpm makes a big difference too.

592 rwhp@7300/540 rwtq "flash" and peaked through the curve at 465rwtq @6200 through a th400 on slicks...... I only made one pull just to see since I tune mostly at the track thats the real deal...dyno's are good for a baseline thats pretty much it IMHO... And sad to say rpm isnt the issue with a lt1 intake its plenum volume and turbulence it creates ....and you can take that to the bank!!!!
