Clutch & Flywheel setup

[Da67goatman]

Background:  TBI 350 converted back to carb with HEI distributor along with np833 4 speed transmission from behind a 250ci straight six all going into a 62 c10. I'm in need of some assistance in picking the correct parts to mate the two. 

I have the factory bellhousing with fork but would like to run a hydraulic master/slave setup for packaging.  It has been so long, I have forgotten about the multiple balancing and rear main options that the SBC has and have never dealt with a clutch that wasn't just a kit for that specific vehicle.  I know some of you die hard manual guys have all this stuff figured out so if you could recommend parts, I would be most grateful.

Look up parts using an 87 R10 350 for MY6 application.

Will that clutch require changing to a hydraulic throwout bearing?  Or can I use an external that pushes the factory clutch fork and throwout bearing?  The old style pressure plate only has 3 fingers vs the many of the newer style.
