Pulled more parts from the 350 today. Pulled the heads just to check out the shortblock and it's just not quite in run-worthy shape. It's just sat too long, so she's got to come all the way out. Lifters were so gummed up that they wouldn't all come out (5 or 6 still stuck). The block is in fine fine shape though, not even any ridge to remove at the top of the cylinders. Just a hone most likely. As for the stuck lifters, they're soaking in penetrating oil and should come right out next time. Might as well order up that 3.75" stroke crank, 6" rods, and new pistons though, right?
Next time out there I'll be pulling trans and engine mounts. Should come out rather easily as all of the extra bits are already removed. Pop the trans mount, engine mounts, and shifter linkage and she should come right on out.
