I don't have much room to talk (my 80e is taking a crap) but did anyone notice Bigtex said 4wheel burnouts?!!? HOLY 4WD BURNOUT MAN! LOL You bought a cam from me Bigtex, did that work out alright?

500HP?Yukon...what's that thing weigh? 6000 or 6500lbs if not more. No Way. Mod that 65 all you want, won't last. Let's face the facts, I am not in denial, 500hp and I am tearing *** every where. So will you. the 65 and lots of weight won't appreciate your heavy foot. Besides heat, those 60 and 65's second worst enemy is weight plus torque/horsepower. For the money you'll put into it to protect it from your right foot, just upgrade to 80e. Again, no room to talk I guess...got my own problems.

Anybody with a Yukon is usually a highway rider as well, I am not sure you'd enjoy a T-400. Bulletproof yeh...no OD though.

I am not worthy of 2 cents, but that's my 1 cent.

 

It will last forever if you don't put your foot into it. If I had your truck it would not make out of the driveway before it broke.

 

This too was my train of thought, but in reality having no OD is only going to hurt gas mileage a little. OD usually drops the rpm about 500 or so. I personally want reliabilty ( mine is also a DD) and I'll sacrafice a little gas mileage.

 

I am running a flp level 5 and now have about 6k miles on it with no problems.

 

I have a 4L65E in my truck and it has lasted many tortures. I have use many bottles of that addicting laughing gas (NOS). Until now I haven't seen no problems yet.
