Ratios vary widely and it depends on your weight, use, etc. T56 is a fantastic tranny, but with the steep 2.66 first and double OD 0.50, it really needs some pretty high (numerical) final drive gears to match. For instance, I have a T56 to put in my Impala SS.
Original setup was 4L60E and 3.08 gears. To keep the same basic final drive spread I switched to 4.10s. T10 is like the first four gears of a T56 minus ODs. Big difference in spread. A while back i was researching what it would take to swap a 5.3 or 6.0 into my GMC 3/4 ton 4X4 with the cast iron 4 speed in it, and what i came up with was a flywheel for a 99-01 6.0 and a pilot bearing for a 98-02 Trans Am or Z28, with my existing clutch being reused. Other than the motor mount adapter plates (6 holes drilled in a piece of 1/8' steel- whoopty doo), that was all it would take to physically get one of those motors into the truck. These same parts would work for any other trans that bolts up to a small block, provided that you started out with a bellhousing that clears the 14' flywheel and 11' clutch.
Kind of off topic, but oddly enough an 8100 is an even easier swap- take the flywheel from the 307 that's in my truck and bolt that up to the 8100 and put it all back together and drop it back in using the existing engine mounts, with only metric bolts being used to bolt the bellhousing to the engine instead of the 3/8' bolts that are in it now.

Std SBC bell housing would be fine? Curtis73 wrote: The LS bolt pattern is basically the same. There is an extra boss in the top center on the LS block that won't be used and one other bolt hole that exists on the bellhousing that won't be used, but 5/6 is just fine.
There are adapters to put almost any trans behind the LS, but GM type bellhousings will bolt right up. LS type clutches/housings are a different depth so you may need a specific flywheel/clutch, but its basically a bolt-in. The flywheel would be the issue, 85 and older with 2 piece rear main seal w/ outside bolt header valve cover use a different flywheel than 86+ newer SBC because of the 1 piece rear main/center bolt valve covers.
