Need help with vortec 350 manual trans swap
 

Morning fellas,
Finishing up my L31 vortec 350 build for my 64 step side and trying to figure the flywheel, clutch and starter situation.

Here's what in the truck now:

-1977 305 (lol...i know...hence the engine swap)
-factory 1964 bell housing and mechanical clutch linkage
-1992 world class S10 speed conversion

I know I have to drill and tap the vortec block for the z-bar ball stud ( i had to do it on the 305 that's in it now)

I know I need the vortec flywheel due to the 1 piece rear main seal.

My questions are:

1. Because there's very low mileage on the clutch that's in the truck now, can I use that clutch on the vortec flywheel?
The reason I ask is that the clutch for the vortec flywheel is 12 in and the clutch in the truck now is 11in.
I'm pretty sure the mounting is the same for a 10.5 and 11 is the same, is it the same for a 11 and 12 in clutch?
Will they interchange or do I need the vortec clutch?

2. Because both the flywheel in the truck now and vortec flywheel are 168 tooth and have a 14 in outer diameter, I can I use the same starter, correct?

3. Because the pilot bearing in the truck now and the vortec one have a .59 inner diameter, there shouldn't be any issues?

Till you put your hands on the fly wheel and see what its actually drilled for I would say maybe on the clutch. Rest of you plan looks fine. The starter will work if the flywheels are both 168.
