LS1 or LS2/L98 into 63 Belair

[Dean 560 SEC]

Yep everyone reckons they know and don't get me wrong next to a 4l60 it's a massive fucking cunt of a thing but the bellhousing is the same size and it all seems to fit except one tab i removed. I also lopped off the threaded end and removed the rubber donut from the back of the box as you can run a normal turbo 400 joint off to save room as the donut would have hit the floor, mocking up the stock tailshaft to the t400 joint it eyeball looks ok, I've got another Belair here with a stock motor and box at the moment so I'm planning to double check, just need my 9" finished to get the tailshaft done and see if I am a winner or loser... either way, you won't need a whole commodore floor, massive overkill

Hey Mate

Are you able to give me any info on what you did to replace the donut with the turbo 400 yoke/ uni? Im in the process of putting a L98 and 6L80E in to a 1982 XJ6 Jaguar and would prefer to run 1 piece shaft with unit rather than stuff around with the donut at the back of the box.

Ive read conflicting commentary on which yoke to use, which length, changing seal, not changing seals...is there a simple solution?

He chopped it off with a grinder and slid a t400 yoke in

If you're removing the end of the output shaft wouldn't it need to be machined so it remains balanced? Surely cutting it off with a grinder could potentially cause driveline vibration?

Any issues since its been installed? How many K's has it been driven?

How is a 1in shaft going to go out of balance cutting a piece off the end of it?

[Dean 560 SEC]

The output shaft is a lot longer than an inch - even the end section that would need to be removed is longer than that. As for how could cutting this off with a grinder cause the end of the shaft to be out of balance...I'll leave this alone.

Problem solved - Ive ordered a Sonnax 3 bolt adapter flange yoke from Jegs in the US which will arrive late next week. $240 including express shipping from the US is a better option than stuffing around cutting output shafts and sourcing a correct length TH400 yoke.

Do you really think cutting the end is going to put it out of balance? Lol... the shaft is 1in in dia not 1in long, removing the end of it is not gong to change the balance of it..

It's pretty hard to get a t400 yoke that's right.
