Outstanding concerns ...

1. EXTREMELY short clutch throw
2. Drive line angles

Anyone have thoughts?

The extremely short clutch throw is probabl due to the master cylinder rod pivot point being too far from the clutch pedal point.
I'm going to be converting to hydro clutch, (nv4500 soon), and the best way I've come up with to get the correct length for the pivot point is to measure the stock clutch pedal out of say, a 94 Chevy with a manual trans and hydro clutch.
I haven't gotten around to finding one to measure yet though.

The drive line angles...I didn't read all the posts, (yet), but I did see somebody mentioned 0 degrees. I don't think that would be correct.
The crankshaft centerline isn't "level" when an engine is installed. The carburetor pad should be level, or close to it.
The important thing on driveline angles is that the transmission output shaft angle matches the rearend pinion angle. Or as close as possible.
