take it wayyyy back
which tci flex plate do you have? waiting for circle d to get back to me, they mentioned the 399753 but that says for ls to 4l60. do we need the one for 2010+ camaro? 399757. and just realized youve got a 6bolt converter so may not do me any good
i think mine may be cracked/damaged. makes some creeking/scratching noise idling, goes away when you blip throttle or put it in gear. couldnt hurt to have a real flexplate in there anyway at this point

I'd recommend it if you're making power and hooking up. The part should be the same, it's a dual bolt pattern and you'll still get a safety and weight benefit. Mine is TCI #399754. Not cheap, I think I paid $250 by getting summit to price match.take it wayyyy back

Seems to be about the same price. for any of them from tci.
You used a gen 4 block right-Ly6? And still 6l80.
Circle d pretty confident in the part# they gave me waiting to 2x check from them. Tci thinks same as I am use to 2010+ camaro as the converter I have is bolted to stock GM now...
But you are actually using this one lol although with different converter mines a 258mm with stock 3 bolt pattern
heard back from circle d, sounds like they know what they're talking about so ordering the one they say i need. should have just done it sooner but i think i kinda ran into this same issue not knowing which i needed before either - circle d had their own billet that was like $550 and i wasnt looking to drop that money on it at the time

I'll just leave this here... I had to make a few videos after seeing @Chrismnj post his. The runs were in Mexico (obviously...) and the truck is running very little timing and pig rich. Lot's of wheel spin out of first gear off idle that will hopefully be taken care of when I install my double adjustable coil overs. Can't wait to get it back on the race track for some 11 second passes, maybe even a 10.9 after getting it dialed in.

one more, back to back runs... IAT temps were getting a little high and pulling timing, might be time to install that interchiller.

These double adjustable QA1 coil overs will be installed next week up front and when I get my ride height set I will measure for a matching pair of double adjustable shocks for the rear. Need to do the free travel mod and install my helpers bags and hopefully it will stop picking up that front tire.

Damn!! Love it 
. Wish mine was that fast--or not--I'd DEF get locked up if I had that much power under my right foot. You'd see me on tv live lol!
