Did they pull the belt for this run?

nope.

Ddddddddddammmn son!

Thats some good stuff!

Good numbers/combo

gotta love the 6.0...guessing stock rear and gears

Them AI 243's are some nice sleeper heads

yeah stock rear end it does have a ls7 clutch thats all..

what mill and gaskets, flycut...come on guys you know the standard questions

im just gonna throw it dont see too many people see over 450rwhp with LS6 heads, damn near 500 sounds crazy. now if it was a 402/408, i could believe this.

if that was a 408 and not a th400 9" id be pissed lol those are some nice numbers from that H/C/I LS2

i have seen 49x with a 236/236 and TEA stg 2.0 LS6 heads...those were the ones i was going to get before i ran into the deal of the century on these TFS 215s...

my new bang for the bust would have to be these or the as cast 220 TFS with a little Brian Tooley massaging...

its my dads car you would have to check AI

I have seen a GTO with a 408 and AI 243's make 500rwhp and it was a stalled A4.

Here is the video of the dyno pull if you don't believe it:

great numbers from AI LS6 heads. i will see what AI CNC 208cc TFS LS1 heads will make when i get them.

Another 6.0!!

OH yeah, I didn't expect those numbers but I'm very pleased. It's just not very enjoyable with street tires. No traction what so ever until about 65mph with the tires I have now Need a good set of drag radials..........

In addition Jeff's old GTO had stock 6.0, AI 243's, FAST, and the cam I run and made around 485rwhp through a stalled auto and over 500 with the belt off and he did not have an EWP.
