1996chevy s-10, 2-wheel drive,hydraulic clutch

lol ( not really)

well i got the clutch and everything back together in this truck and its still has a terrible knocking comming from the back of the motor. The shop mechanic says that the noise is comming form the bellhousing and its the clucth causing it. I know the motor is screwed(4.3 vortec 168,000 miles) it sounds like a rod is gonna come through the oilpan anytime now. My boss says that i put the wrong clutch in this thing when i know i didnt and he says the knocking is because of the wrong clutch installed. Everything went together smoothly and i know its all in right/ torqued to spec. My question is......... is it possible to put the "wrong" clucth in something, or am i right and the motor is done.

this truck is a light service truck(AAA)
motor wont rev over 4 grand and wont pull the truck down the road.
no oil pressure b4 knocking now has great oil pressure but sounds like its gonna come apart



p.s. my car is running great:nice: its a ford ya know
