I liked it but not something you want on a street truck, chirps tires while turning and is not wet road friendly. Your wheels are definitely locked together ha ha . For the money and since I've got spare axles I'm gonna buy another one so I can get the truck off the lift at work before the boss goes to bit chin.

bootlife PM sent...........jansen if you didn't live soo far away I could loan you a whole axle "identical" setup haha

How much those pistons run you? I didn't know GM sold oversized pistons.

Lookin good , why didn't you port those 243's!?! Looks like you have access to cheap machine work like I do lol! Did you get the rotating assy balanced? How high you planning on twisting it? Which injectors you using ?

How much those pistons run you? I didn't know GM sold oversized pistons.

I wanna say they were $65 my cost, that was with piston,wrist pin, and pin clips. They are GM stock replacement for LQ9/LS2 motors, due to the fact that GM made the bore sizes between 4.000-4.004 (LQ4)-4.013-4.020 (LQ9/LS2)..... Either or the piston's are available over the counter Stock Replacement Piston size from GM is 4.000, Optional GM Replacement piston size is 5mm oversize which equates to a piston over bore size of 4.020th's, the new displacement with those pistons in the block comes out to 368ci......So I rounded it up some to 370ci lol

I used this Formula to achieve my Displacement


It Works like so for any motor...........I used my engine info for my application. Everyone else's will be different........................ Bore Squared (4.02 x 4.02) = 16.1604 Divided By (4) Equals (4.0401) Times by Stroke (3.622) Equals (14.633242) Times by (8 PIE "25.12") "pie equals 3.14" so (8 Times 3.14 "pie" = 25.12) Equals 367.58703 Cubic Inches Of Displacement

Just because I don't tell everyone they are ported doesn't mean they were ..........they got a very very mild scuff and smooth, basically just a quick puff with a flapper wheel to make them look pretty. I didn't want to spend the extra $$$$ on porting them, because I will be swapping over to LS3 heads very shortly that WILL BE ported. No balancing on the rotating assembly, It was all new from GM when I bought the crate motor, But it was checked for accuracy. (Stock LS2 bottom end btw). I'm shooting for 435-465hp on motor and as close to 400rwhp+ as possible. I have a stock TBSS intake with the FAST 92mm on it and stock TBSS injectors that I will be using for now until I get it squared away..........I did use TOTAL SEAL RINGS and they did get gapped for juice...just in case I don't reach my 12sec goal N/A

Nice build thread.

Thanks!! Make sure to keep checking back for progress and updates
