?'s for a 59 gmc engine swap

[vwjohnny]

Hello again fellas.
I'm having some issues with my GMC 270 powerplant (mostly due to the fact that it sat for several years). Basically having a hard time finding parts and that they are expensive. Now dealing with a blown head gasket and cylinder scoring. I've spent the last few days searching only to come up empty. Anyways, my question is this. How hard would it be to drop a Chevy 350 into this truck? Could I mate it up to my existing 3 speed? Not looking to run this truck at the drags. Just need it to get my dirt bike to the desert, pick the kids up at school, and run to the store for a gallon of milk. I want an engine in it that is reliable and that I'm able to get parts for. All help appreciated!
