Default T56 bellhousing clarifcation??

I have a T56 out of a LS1 car, I also have a 70 chevelle, and a spare BBC laying around, They all need to come together. I know a LT1 T56 will bolt to a STD small or BBC. The LS1 T56 will bolt on, but has a longer input shaft.

Here is where it gets muddy, the BBC is exteranlly ballanced, I have a steel SFI flywheel for the motor but it is 168 tooth version. It does go into the bell housing So what is the simplest way of mating them? I have been through quite a Few T56's so I would have no problem swapping the input and the bell housing BUT does the 168 tooth flywheel fit? Or where do I find a externally ballanced 153 tooth flywheel? Am I stuck buying a adapter bellhousing either way? How do most guys do the linkage? Adapt the LS1 or LT1 HYD stuff or use mechanical?

Also I am thinking about making the speedo work........

Maybe one of you guys knows or has been there done that.....

The cleanest and easiest solution is the McLeod adapter plate and extended pilot bushing that allow you to use any standard Chevy or aftermarket bellhousing, a mechancial clutch linkage and the flywheel of your choice. The entire adapter setup is about $200 from McLeod. (I don't care for the hydraulics on an LS1 transmission because if anything goes wrong with the slave cylinder you need to pull the transmission to fix it.)

McLeod also lists a modular bellhousing which could be used to adapt your engine/flywheel to the LS1 T56.

Finally, I'd recommend a Heim joint mechanical clutch linkage. Very smooth and, obviously, easy to adjust.

Thanks for the info, I am looking into it as we speak.

leads on the Heim Joint linkage or do you just build you own?
