Probably just a worn clutch.
Any idea how many miles are on it?

not sure since the odometer turns over every 100k miles. Guessing 230k or 330k.

Yea...I just put another engine in and so I was afraid i put somthing back together wrong beings i had the tranny out etc. Could easily be a bad clutch tho.

what, Jesus wasnt looking out for ya??!???
just kidding. if you did it wrong, it wouldnt work at all.
i suspect worn out clutch disc, i just put a new kit in mine.
i used a south bend clutch. mighty pricey tho. LUK kits are 1/2 the price.

My luk was 169 at pep boys and 75 to grind the flywheel.

The only thing I can think that you can do and have it work at all (but not right) is putting the clutch disk in backwards. When I took my truck apart, I figured the clutch was worn out based on the way it behaved the short time I drove it. Nope. Its basically brand new, but the disk was in backwards and it ground the rivits in the center section off against the flywheel bolts. Speaking of which, you put sealant on the crank bolts right? They will leak oil if you don't and could cause your problme if oil is getting on things.
