You are going to love the SOHC vs the push rod motor. I remember swapping mine and being soooo juiced on the drivability difference.
to be fair, a radiator drain and 6 bolts takes my core support off. trans bolts, engine mounts, 3 wire connectors, two fuel lines and a y pipe freed my engine. it was all pretty easy to be honest since its all sure stripped downdamn. I barely got a motor out in a weekend. HAHAH
