F body Torque converters

[Mrich0908]

Do gen 4 V8 F body Torque converters fit vortec (mines L31 97 yukon 1500 4x4) 4l60e flex plates? I found a good deal on a new TC I need for my build but it goes to a 4th gen Fbody.

The simple answer is no. There's an adapter and whatnot from Scoggin_dickey, but probably pushes it out of the budget.

Heres my build im sure its with in budget . Im at the end of a 383 forged scat crank 6in rod stroker W/ forged -24cc wiseco pistons , 24x conversion , mpfi single plane intake , seimens deka 80# injectors , 1200 cfm 4brl throttle body , dart platinum heads comp cams XFI cam and magnumn XD roller rockers for a compression ratio of 8:5.1 pushing 20 psi. Using HP tunners for tuning.
But the good thing is Im a machinist so theres a great chance I could make the adapter.
You do know im asking about the torque converter and not the whole tranny correct?
Got a link?

I thought you were buying it because it's cheap lol.

Since you're a machinist, you can either slot the holes, which is what I would do, or this, http://www.gmperformancemotor.com/parts/19154766.html

Cheap as in 350$ for a 600$ torque convert. Its a revmax stage 5 brand new in the box .
I think thats a killer deal.
Thanks for the link .

 

[Jrgunn5150]

Absolutely, I'd grab it up too lol.

Why would I need a whole kit for just a torque converter . Thats for putting a gen3 tranny in a gen 1 everything but the TC is a gen1.
The 4l60E and flex plate are the matching transmission from my 97 yukon , Im only asking about the torque converter by its self .
Im sorry if I seem confused its because I am .

Because the holes in the flexplate for a Gen I/II motor are slightly different than the holes in the flexplate for a Gen III motor.

Like I said, you can either slot your flexplate holes, or get the kit, or see if you can get the flexplate separately, I don't know.

I get it . One is 300mm the other is 298mm . Jeeze im tired I couldnt wrap my head around that lol.
Ya ill probably slot them. Thanks

I'm guessing one is probably SAE, then the Gen III went all metric, but yes, that's the gist lol.
