I have a toploader that bolted up to a FE. Does anyone know what the difference in pilot bearings is? Is the big block input shaft just bigger or what, and also does anyone know what that dia is??

Thanks

Don't know the specifics but I know the big block toplader has a shorter input shaft than the small block.

 

That's not good. We haven't tried to bolt up the trans yet, but he's supposed to get his clutch today, so hopefully tomorrow we'll be able to bolt it all up.

 

it will bolt up really easy because the input shaft will not be going into the pilot bearing. Take some good messurements before you put it together. It think you will find it will be too short. i could be wrong.

 

You're correct. The input shaft on a BB is shorter than the SB input shaft. That kind of sucks!!

 

I you can find an old small blcok toplader 3 speed I think the input shaft is the same.
