Sounds good!

Is that pre tune? Lots of smoke on decel, looks like unburnt fuel.

^ Look at what he has on this thing, all LS6 heads and intake and a small stock throttlebody! Wait until he puts the LS7 top end on this thing!! It's just choking this thing. The torque is monstorous already......can you imagine?! Traver

Smart like stick.

Look at the top end!!! His torque would destroy you on the street!!

Looks good for what you got. Id change the headers to 2 inch Kooks with ls7 flange. Go to ported LS7 4.1 heads from ETP with a 1.85 rocker. Then either a LS7 intake or a Beck LS7 sheetmetal intake with a 90mm or 100mm t-body and a 100mm mass air from lingenfelter. And top it off with a true duel exhaust. Your car should be close to 575-600 hp with the change in parts.

The guys from Eastside are selling some complete ET 4.1 LS7 heads in the for sale section really cheaply.

Every car I have seen on the dyno that makes good power dose this to some extent. That happend to be the first good pull after we leaned it out. It was burning out all the carbons and crap in the engine from the pervious crap rich tune. the last 2-3 pulls where alot cleaner!

Why would you even make this post?
There is a member here trying to provide some knowledge to other's and shareing his experience with this build and all you can think of is something negative.


I don't know you and I am sure your a nice guy but when there is a someone on here trying his/her best to provide useful info for other's, learn how to keep your negative thought's as thought's only and keep your finger's off the keyboard.
Your post does nothing for this thread except uses space.

BTW after looking at your mod list...
Patriot Stage 2 heads
PRC double springs up to 660 lift
Fast 90 intake
nick williams 90
Fast 36lb injectors
Chromoly push rods
LS7 lifters
TORQUER V3 cam 231/234 .643"/.598" 111 LSA 2300-6700 RPM Power Band with a peak around 6400rpm
powerbond underdrive pulley

Mezere Electric water pump "chrome"
Ls6 ported oil pump

Kooks 1 7/8 JET HOT COATED headers with kooks Y pipe

You have a solid 5,500 in mods there, and therefore you wouldn't have 13,000K still in your pocket.
You have a Fast 90/90, and a electric water pump, both of which are helping you make that power of 462.
The 454 combo is being killed by the topend, and I am sure by next year this will be much closer to 600 RWHP then 500.

Nice work! I'm interested to see the final results after you get the top end changed out next summer.

I've seen videos of my car puffing smoke on high rpm decel...I always thought it was pulling oil through the PCV. I still have the stock PCV setup and I know it sucks oil cuz the intake is coated with it. Maybe you need a catch can?

To this. My car is completely stock save a Blackwing and the first time I had it dynoed (67000 miles), on the 2nd pull I thought he blew every ring I had it smoked so damn much. Reese (Reese *** @ MTI) said that it was just because I don't drive it hard enough :shrugs: IDK. Made awesome numbers for stock anyway so I was happy!

I think I remembering you saying to had it dynoed at Doug Rippies, thats here in Buffalo, MN correct? If its the same shop, I dynoed 20HP less there and also from what I have heard from other people, the dyno is a little stingy.

dynos are dynos. people throw around well that dyno is stingy or there is to high. it is what it is. dont be one of the guy making excuses for his dyno numbers. you know why you did not make the power that it will when you change your top end. i am sure you car still pulls hard as hell as it is.
