Just put engine in last night. 10 times the work it should be to just install engine. Mandrel only 1/2 inch from radiator. May have to get another one, this one is a moroso and has two spacers along with one pulley for the vac pump, one pulley for the alternator, and one for the Ron's pump. I may be able to cut the mandrel down a bit. Had to cut out rear motor plate to clear 4 1/2 stroke crank. Vac pump belt only 1/2 from chassis upper rail. Radiator's close so may have to reroute water lines. Everythings new and pretty though.
