First off we need to know a few things.

When you put the truck back together did you put in any new carpet 
or floor mat with insulation beneath? This may cause the 
pedal to stop before its full travel distance. 

A full inch of free play is a lot on a new clutch you may want to 
tighten that up to maybe a half an inch. This can and should be 
readjusted after a breaking in period of say 500 miles.

The input shaft bushing may need some lube I usually put a small 
amount of high temp lube to the end of the transmission input shaft 
as well as a little on the clutch splines. I work the clutch plate 
over the splines a few times then wipe any excess off. 

Did you resurface the flywheel? Was it done on a centerless grinding 
machine? Is the return spring spring hooked up? Are any of the 
linkages worn? Does the pedal come up the the stop on the 
floorboards? Is it binding on the sides of the holes thru the 
floorboards or the rubber/felt gromets that sit in the floor?

As a last resort pull the trany and check to see if the spring 
side of the clutch plate face the tranny. Lube the splines and input 
shaft and bushing while its out.

Good luck try the easy stuff first.
