400-435 RWHP? What kind of compression will you end up with? That looks to be a fun build.![Driving](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_driving3.gif)
My old LS1 with Patriot 243's and cam, FAST 90/90 and LG street longtubes got 450 RWHP. I was at about 11.2:1. Since breaking it I am going to build a 404 shortblock and put all my top end goodies on. kicking around a new cam though.

My build is as follows.
- LPE CNC 243 heads full roll, which I guess is stage 2.
- LPE GT-11 Cam. Specs: 216/231 duration, .631"/.644" lift on 118 LSA
- Dynatech headers
- Corsa Cat Back.
- Cats are there.
- FAST 92. Ported by me. This picked up 31 rwhp over stock LS2 manifold. Get the FAST intake.
- Stock TB. Ported by me.
- Yella Terra roller rockers
- Comp Cam Hi-Tech push rods
- LS3 card style MAF installed in older Halltech Killer Bee bridge.
- K & N air filter
If the heads are off the motor, have them pressure tested. Mine developed a crack on #5 intake port and was leaking coolant into the cylinder. A local shop welded them up good as new. Stock head castings can get thin during the CNC process.
I tuned the car myself and it starts and idles dead smooth at 675 rpm. Most people never suspect it makes this kind of power. Driveability is stock. I love this combination.
Last week, I switch to the LS3 card MAF and Halltech bridge and picked up 17 rwhp over the stock MAF and K&N assembly. Very shocked.
Torque curve is virtually flat from 4700-5800 rpm at 420 rwtq. Makes the peak HP at ~6000 rpm.
