Congrats


Nice numbers. I would be tempted to coax alittle more out of the tuning to get the 500 mark for bragging rights if nothing else. Good numbers. I'll bet it pulls hard.

Damn good numbers buddy with LS6 Heads....Congrats

That is a beast! Congrats man. Like 406WS6 said, try to sqeeze that extra 5hp out of her. I'd like to see a 500+ whp in your sig in the near future.

We tried to cool the heads down and make the money shot run for 500 but the power went out and the dyno crashed but i will be back to try and get the 500 mark!!!!

What is your compression? My guess that you have a lot of power left on the table.

I can see a 530+ rwhp can be squeezed easily.

Congrats!

I agree, bump the compression up and you should easliy see 500rwhp. Do you know what the heads flow???

Great numbers.

My guess is his compression is around 12:1.

With a 64cc, i bet its around 10.6

Congrats on the #'s.. The Moser with 4.10's are masking your true numbers..

Badls6SS

iTrader: (7)

Your right on the money it is actually 11.9:1

The comp. is high enough it will only take 24 deg. timing we tried 25 and it started to knock. So on 94 octane i think that is about it. I'll go back in a little bit after i put somemore miles on it and try for 500
As for the heads i'll have to check i have the #s @ home

I`m running 11.3 and we could only run 22 degrees timing!! But my ET heads arn`t helping out either!

those are some pretty good numbers i have the shaved 61cc version of those heads that are also going to go on my 408,I was curious on how they would perform on these 408s do to the fact that they are intended more for stock cubic inch motors.PUT ON A PULLEY AND YOU SHOULD SEE THE 500 PLUS MARK EASILY.DID THEY FLOW ALL THE WAY WITH THAT HIGH LIFT CAM,THATS WHAT I WAS REALLY WORRIED ABOUT MY CAM IS A FMS 246/250 DUR.629-633 LIFT AT A 112 +3 ADV.SO IF YOURS FLOWED ALL THE WAY THROUGH THEN I SHOULD BE FINE.

i wonder what AFR 225's would do for a setup like this.....that would be interesting to see.

great numbers,and nice setup

These heads flow pretty good i don't think u will have a problem w/ that cam. just make sure to check piston to valve clearance. That is why i built this 408 because i had the same heads as you (61cc) and changed the cam in my ls1 and did not check ptv and i dropped the #1 intake valve and the rest is scrap aluminum.

What port volume are those heads,makes me wonder why I have low peak #s with my afr205 and big cam?

Thats the first thing I say with his setup. How much more freaking compresion do you want? You guys saying he can squeeze more power out with more...........LOL.
