Alex drove mine down the 1/4 a few times on 275 street tires on a stock 10-bolt! He couldn't even go WOT until he was past the 1/8th mark because the car was breaking loose with ease. He was feeling the pedal all through the 1/8th, and only went WOT through the last few hundred feet.
I wouldn't drive it because I didn't want to break something and have to pay for it, so Alex offered to pay for anything he might break, so I gave him the keys, lol
. He still netted an 11.9 pass at 123mph without even getting on it until the end. If I get a 9-inch and some slicks, I can see mid 10's @ 127+mph, IMO.Hell, my old setup went 11.8 when I was ***** to the wall from start to finish. I am pleased with the 408.

WOW strait from the dead i was the second to post over a year ago. i didnt even have my heads yet. wow have things changed. did the H/C and blew that up and now got the 402 in and do i love it. should have done it from the start....!!
My 408 dyno numbers were low but I think I have too low compression, and a shitty intake. Mine was 450hp/440tq. I have a stock ls2 90mm intake, and I did the math yesterday and Im at 10.4 to 1 compression. I have patriot 72 cc stage 3 heads w/2.08 1.60 valves 225cc runners, and a Texas giant cam. I think by going to a 64cc stage 3 with 225 runners I would be in the 11.3 to 1 area, that should pick me up 20-30 rwhp. Im also going to get a fast intake, maybe between the two I can see 500rwhp. ????????????
I know with a set of AFR 205s milled to 66cc with the same Giant cam as you my friend put down 505rwhp with a ls6 intake on his 383... So you might want to think about that.

HKE 408
Greg Good Ported L92 Heads
GMPP Carb Intake (unported)
TH400 w/ Nitrous stall
244/248 Cam
Ford 9 inch w/ Spool
TT2 Wheels and 28 tall tires
Car put down 455 uncorrected..... ran a 7.9 @ 93mph w/ a 1.9 60ft on motor w/ a partial SD tune.
Fixed the tune after adding a maf and ran 7.6 at 94.5mph w/ a 1.7 60ft on motor with the nitrous stall.
I am sure it was doing right around 475-480 corrected after the maf tune.
