I will have almost the exact setup as OP except MS4. Heads are sitting in my back room just waiting to go on. Start getting my heads off last night

Looks like a pretty solid build you have going there, I am curious to see how it does on the dyno and track.

im running the same set up with 215's a trex and the 102. I will have numbers on the 7th of march. Just waiting for the tune.

Are the Prc 227 heads the same for the ls2 as the ls1 version. Im probably going to get these for my ls2.

I am hoping that this combo produces some really good numbers, however I am more concerned with how the car will drive and respond to the mods than just numbers. We'll see!

grap some sort of a ram air too...easy 20rwhp just in that...looks like a very well put together build...should give great results

Austinma62

Your running stock gears? Why not something more aggressive?

Cat out of the bag aaron lol. Should be a nice setup like chrs1313 said ram air will help alot with the mods your doing. Best mod for the money

I am going to first see how much power I will make before I decide on whether I want to invest in a Moser Rear or just gears. More than likely a Moser.


So does anyone have an estimate for power? I am trying to get over 450 to the wheels if I can, but I am not sure what kind of power these heads will make. Throw out any estimates/guesses on power, I welcome your opinions!

LOL. I new youd be lurking around here Robert haha. Definetly gonna get the hook up on the Chris1313 ram air setup to put the icing on the cake you know!

Being a stalled auto the numbers will be a little lower than with a 6 spd, but i would still expect it to make 450+. Mine made 448 at 6200 with stock 125k bottom end, almost the same cam and inferior heads and intake. It was through a 6spd though.

Do the 227's ship right away or did you have to wait a few weeks?
I cant wait to hear about some results. I want these but really have not heard much about them.

Solid combo there. That's cam is perfect too. Won't have to fly cut with it. Let us know how it goes.

It's about a 2-4 week wait for the heads, but these heads are going to be well worth the wait. I can't wait!

Thanks Detoxx, I really hope this build gives some really good power so we will see. The build will start in a couple weeks once all the parts arrive.
