LS1 Build Thread
LS1 Build Thread Hi Guys,
I will update this thread as the car is built, gets dyno'd, etc. Just to help get some solid information out on how this setup does. I have decided to go with the "power under the curve" type build, so here are the mods I will be installing over the next few weeks:
-PRC 2.5 5.3 heads
-228/232 (XER lobes) on 111 LSA
-LS6 Intake (for now)
-Ported LS6 TB
-Ported MAF
-ASP UD Crank Pulley
-Monster Stage 2 Clutch w/ 18lb flywheel
-TSP LT's and ORY
That is pretty much the build as I can think of it off the top of my head. I am doing all the supporting mods (Katech rod bolts, Trunion upgrade, oil pump, 42# injectors, etc. etc.) as I do plan on spraying the motor sometime down the road. The car is a 99 Z28, T-56 car.
I really would like to see the car put down 450whp (When you dream, you have to dream big right? Haha). I have seen similar setups make anywhere from 420-440whp without doing the "extra mods" like the lightweight flywheel, UD pulley, taking the plate out of the exhaust, etc. etc. so I am hopeful. The car is on the stock 10 bolt so that will help keep the dyno numbers up as well. Will post up soon with pictures and dyno results.

Heads came in today. For a budget head they look good, but I was surprised at how much "rough casting" was still showing after the CNC. Here are some photos. My camera absolutely sucks, I know.
I probably won't be able to get to working on my car for about 1.5 weeks so stay patient, lol.

Got the rod bolts and the heads/cam installed today. Still have to torque the heads yet. I will probably do that and the oil pump/pan and call it a night.
Some pictures:

Seems like I didn't get all that much done today.
Oil pump:
Windage tray/pickup tube:
Front cover/pan:
Made sure the pan was flush with the rear of the motor, etc. Installed the polyurethane motor mounts today (more time consuming than I was hoping), and I also measured PR length. I am getting a very short PR (7.325" would be perfect) so I am hoping I did something wrong (I don't want to have to wait another week for more PRs).

Made some progress:
I am seriously bummed that you cannot see that PP once the transmission is bolted on.
Hope to have the car rolling tomorrow.
