So its time for my yearly major mods As many of you know, i blew my tranny up back in january. My GXP has been sitting in my driveway since 
I just ordered my new triple edge tranny. I am getting 3.29 gears, upgraded torque converter, and upgraded 3rd gear.
I am also doing some more work to the engine
I am going to put in a larger cold air system and larger throttle body. I am also putting lowering springs on it.
Also some people on here seem to think i have stroked my engine or bored it out. This is not true. My pistons are slightly larger but its negligible. In fact i actually lost compression from them cause the dish is deeper.
I will start a new thread when the car is finished. I am expecting it to be done in like 6 weeks.

Good luck with the trans but be prepared to wait for a long... long time.
I ordered my stuff about 5 weeks ago and haven't heard a word
I trust Dave though so I'm sure he'll get things out when he has the time.
I spent about 2500.00 in hard parts. 3.69's and 3000 stall with the race rebuild kit, input shaft and other small stuff.
I'm planing on sending my Ported LS6 intake off to TPiS to have them do the LS2 90mm flange mod. I'm going to use the LS2 tb and MAf with the proper tubing and filter. I'm also sending my heads off for some CNC porting and more milling. I'm hoping to add about 40 more WHP.
Intake mod is 350.00 and the heads are 750.00
More downtime lol but I wanna be able to out run most Vettes
Both shops told me to expect more so we'll see!
You have PRC 2.5 243 heads correct?

I wouldn't worry about a bigger cam until you get some more passes with the new transmission under your belt. If anything, I'd highly recommend N2O if you want more power... you have a built motor. Even paying someone to do the install and getting all the goodies, you can't beat the HP/$. Keep us posted with your results!

if ur gonna put in a trans anyway, just throw in a cam for N2O. rock the cam for now and make nitrous next years add on
a cam in my eyes is a must if i ever get a built trans.
we have a tiny stock cam and any LS engine shows pretty good gains gettin rid of the stocker
used cam couple hundo, 918's a hundo. def worth the 20-30hp. thats the price of a ls6 intake.....

nmp is right. I have a custom cam and i dont think a larger cam will gain more then like 10hp. Cams in the ls4 cars dont do a heck of a lot at least for the money. N20 is the way to go. I am planning on running nos next year. I havent had my car working for more then like 2 months at a time lol I want to get through the summer. The cam, engine, and tranny are built for a 200 shot in mind

o gotcha, sry I did not read your signature thats says u have a cam. I was just stating over a stock cam the difference is worth it. Hopefully one day Ill get a trans that can handle even the stock power though

Whats your compression ratio mongoose?
I just checked my danamic compression and I'm pretty much pushing it at 8.0 ish (92 octane)
I was going to mill my heads but then I'd be forced to retard my cam timing. Your cam is bigger then mine and I know your running PRC II heads. Did you change the pistons? I would think with your cam you'd be running 10.5-10.75 static.
Can you PM me your Intake valve closing point @.050?
