2002 H.O. long block swap

I have a 2002 dodge 1 ton 24 valve. The engine started to knock a few months ago, pulled the oil pan off and checked all bearings and wrist pins, but can not find any problems. I have talked to local shops about rebuilding the motor and have been quoted anywhere from $4,000 to $8,000. For less than that I can find a running engine or long block but can not seem to find an H.O. My question is: is there and internal difference in an H.O. and a non H.O. motor, if so will a non H.O. motor work in the truck and bolt up to a 6 speed transmission. Thanks, Nathan

only difference is compression ratio. It will bolt up and work fine, just make sure you use the SO pump.

That knock could be a injector problem... Or a VP44 problem (timing issue)...

Just to give you something to try to save you a buck or two... (Shrug smiley)

Thanks for the imput, when I put the oil pan back on and fire it up is there a way I can check the fuel pump myself? I thought it was in the bottom end because I put a stethascopeon on the block, but the motor is so noisy I could be mistaken.
