3 speed on 5.3 questions
I have an 09 5.3 lmg I am outing in a 69 nova and I want to reuse my transmission due to money issues. My problem is I just bought a flywheel for the motor and now my bellhousing doesn't fit over the flywheel. I remove te starter and tried again with no luck. Any suggestions would be helpful.
Thanks

Thanks for the info the flywheel info will help but my problem is the bellhousing is too small for the fly wheel and I know the flywheel is right because the starter matches up. I don't think it will make a difference but the bellhousing is from a 6 cyl. Thanks

your old 6 cyl is normally a 158t Flywheel and the Gen III/IV is a 168t .. The old 6 cyl bellhousing will not fit over the 168t flywheel.. but I am assuming here. cause you have not stated specific information on what came from where..

Since you say flywheel and not flexplate, I'm assuming manual trans (3 speed muncie/saginaw with 10 spline input). The 168 tooth LS flywheel will need a 621 BBC bell housing or the Keisler version with the extra LS bolt hole.

I know this is an old thread but wanted to ask OP how this turned out. Op - are you around? How did the Saginaw 3 speed mate up to the LMG? I'm in the beginning stages of the exact same swap. THANKS!

Anyone check this anymore?
I know this is way old. But is there any luck or any info that can be given. I am in the middle of this same swap....

Launching!
I put a TKX behind a Gen V 5.3 It does require a different offset bellhousing, as did my TKO/LS3 combo.
Note to check engagement depth with 5.3's as if the crank pilot hole is too shallow you will break you block tightening it down.

Another item to check is test fit the bell housing on the block - my 5.3 had some bolt heads on the cam cover sit too proud and not allow the bell to fully seat.
