just want some of you guys opinions on what it will run and make power wise


It's a ls2 block bore the 4.005
stock crank
scat rods
dss forged Pistons with -5cc valve reliefs
patriot performance 5.3 heads about 10.6:1
231/239 comp cam
Ls6 intake
Full exhaust
Racetronix fuel pump
Performabulit stage 2 4l60
Fti4000 nitrous stall
Stock 10 bolt
3.73 gears
Going in a 98 ss weighs 3500 with me in it 275 60 15 m/t drag radials it's goT comp engineering shocks out back bmr torque arm and subfRame connectors It's got a nos plate on it will be seeing 200 shot but was told bottom end will handle 300 im one hit no problem what do you guys think?

Hard to say since those type of dynos seem to be all over the map

granted and this is a stingy one i have herd !! so we will see just looking for a ball park of what we will see with the mods we got

I'm going to guess 440whp

that's what we hoping 440-460

a lil more technical question for you guys. if we raise the compression to say 11.5:1 what power difference will it make ?

The compression bump should be worth maybe 5-10 hp on its own

400-420rwhp seems more likely on a Mustang, 440+ through an auto and a stingy load bearing dyno is a stretch but I wouldn't worry about it, it will run hard. It's also going to depend a lot on whether the converter is locked or not.

A full point of compression would probably gain 3% HP. I'm poor at math but that should be around 15hp crank.

Please post when you know, my new combo is going to be very similar:

LS2 stock shortblock
Cam Motion 230/238 .620"/.600" 113+3 cam
hand ported 799s milled .010" (11.2:1 estimate compression)
Fast 90mm
headers and 3" duals
powerbond underdrive
built 4l60e w/Yank 3600
12 bolt 3.42

well boys we didn't make it to the dyno. idle was being a pita and its a 98 car the the uploading on thins thing takes forever! 11:30 last night and we weren't finished. we should get things squared up tonight. trans keeps shifting from 1st to 4th so its causing issues. we got the afrs closer to where we wanted it but not set yet... 11.8s right now was 10.0s car picked up alot for that looking for 12.0 12.5
