LS4 builds N/A builds

I have been getting flooded with PM's from members wanting to know about my build, so I figured I would post my build thread, and the threads that have inspired me. TURBO BUILDS ARE IN THE PREFORMANCE PARTS STICKY

I just wish GM was still making the 1" chain for the 4t65 so someone could go crazy with a build... I have a build in mind but its hard to bite the bullet and try it when IDK if the tranny will be able to handle the power I really want.

RosskoE85 is putting down over 500whp and his 7/8 chain broke. I was told to replace the chain every year with continuous abuse.

Who cares about the 4T65E-HD anyway?

I just finished my DOD delete and cam swap using a cam with identical specs to the GM Hot Cam, only .525 lift on both sides with 112 lobe seperation and 219/228 duration @.050. Besides having the compression ratio bumped up to 10.8:1 by milling the heads, everything but the valvetrain and timing set is stock. I put down 270 fwhp @6600 rpm on a dynojet. The shop said stock LS1/Automatic cars put down similar numbers on their dyno. I also did a TEP stage 2 trans with all available upgrades and a big external cooler. I will be driving the car for the first time since the swap tomorrow. I figure once I do a 90mm LS6 intake, LS2 TB, LS7 MAF, headers and a new exhaust, I'll be around 325-350 fwhp @ close to 7000 rpm.

I broke mine last summer too. Dave at TEP said that on higher hp cars it should be replaced at least every couple of years if you're leaning on it. Luckily mine didn't do any other damage.
