Billet Flexplate 650rwhp?

Its hit and miss on that. Some have been fine running a stock flywheel and some have not with alot more power. I'm still running a stock flywheel in my truck.
Stock is fine at 650 hp. The installer has a lot to do with this.
Most likely not when making 650rwhp. Good to know tho cause ill be in the 650-670range here soon.
I have seen quite a few faliures and didnt want to take any chances so Henry hooked me up with 1 at my request

If you got the cash and your already planning on digging in to the trans it wont hurt.
Ill be running that hp if not more and a stock flex plate. Mine still looks like brand new at 500-550hp and 36k

I ran a stock flex plate all last year in the low 10's high 9's , it was still perfect when i pulled it out , I have ran across many cracked and a few broken , HP didnt seem to be the common denominator though , so i guess its any ones guess , I wouldnt run the billet unless you have to , I personally like that the stock piece has some flex to it , it could save some shock load on other parts.

Stocker here.like Trent said above , i wouldn't do it unless I had to.
Most stock flex plates were installed by GM.
I was refering to the trans installer numb nuts.
Attention to the dowl pins and proper bolt tq has a lot to do with the life span of the flex plate.
I've been running 10's for 3 years at 7000+ lbs on stock flexplate
I feel a lot better about re-using my stock one now. Yay! More money for other parts!

Make sure you check fitness on converter pilot. Most need to be machined or you will destroy the pump.
x2!!! Ive seen/noticed the same thing.
I like to hear things like this. It saves me some money for the time being.
80k mi., 500+ time slips, dyno, sled and plenty of street fun all on the orig. stock flex.
