Hello all,

I bought a '95 K2500 ECLB 4wd throttle body 454 that just started chattering at me. I'm on the fence on new 454 crate engine or an LS conversion. Those big blocks of that vintage were pretty weak, so I started searching for some conversion information and ran across this forum. I'm hoping I can find some info to help with my decision. I don't know if the 4wd complicates things or not.
