83 Mighty Max G63B - looking for an engine

[geezer101]

Look at Mitsubishis using single cam 4G63 series engines (earlier Galant 2.0?) All of the 4G6X blocks and heads are interchangeable so if you get stuck, you can use a twin cam block and bottom end and mate it to a new/reco'ed SOHC head. Use a '6 bolt' block (1G Mitsu/DSM) as this will save you headaches with stuff like sumps etc as they are the same design as the 2.0 G63B truck engine. There are added bonuses with using these engines too like a bigger capacity oil pump, oil squirters for the cylinder bores and provisions for a oil cooler.

*edit note - using a short block 4G63 will require swapping the crank pulley and water pump for RWD. The water pump on a FWD redirects the radiator hose from the 'back' of the block via an external pipe, the water pump housing is low profile and the belts are ribbed. You could mod the water pump with a freeze plug and some fudging to run the ribbed belt but you'll need the matching alternator and have to set up an electric thermo fan (another worthwhile mod). This route will also open up the option of adding...A/C!
