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 ?

Nice build thread.

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

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 ?

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

Some more updates

Russel 3/8 Quick Connect Fittings that I used on the fuel rail/fuel filter/ gas tank



Rear backing plates and drums cleaned and prepped for my swap to 15x10's for the rears ( parts supplied courtesy of Blacstar, thanks bro. Assembled with help from some pics from 02camaross )






Rocker Rot




And the new rocker replacements....It's better to spend the money on the more expensive one's the first time then buy cheap units and replace them twice










Rear leaf springs cleaned and painted with Energy Suspension bushing's installed

[MrHorsepowerLSx]

All cleaned up before the Stevie Wonder treatment







After the Ray Charles treatment







The reason your shifter arm breaks......Need that little tit on the bottom to stop it from over extending past first and winding up in your lap.






The 415K+ 4.8 finally sh!tting the bed!......click pic for video

[MrHorsepowerLSx]

4.8 coming out









And out it is




The reason the truck had vibrations and the converter shuttered, 1 broken bolt, 1 backed almost all the way out, 1 finger tight.....it came that way lol ( Jansen was right about the trans being eff'd up haha)






Prepping the truck and motor....someone put the AC tensioner on upside lol....was corrected before install lol






In ya' go!!
