Good Morning. I'm new to this site and forum however I've known this site for 20 yrs. I bought my 1st diesel back in 2001 1985 Chevy K20 (6.2L) "J" code which I only enjoyed driving it for 9mns and broke down. After 19yrs of sitting I decide to bring it back to life (yay). I need some help here I recently bought a completed drop-in from a guy who didn't want the engine for $250, I’m not 100% sure if it was a "J" code, vin # was remove long ago off truck.
What's the difference between my old 6.2L (14022660) and new/used engine (12552929)?
I would like to still use my current transmission and transfer case if this new engine works. Any help you guys can give me is greatly appreciated. Thanks Bits
