Buying Short Block

Honestly - it sounds great. No concerns with the compression ratio. it might have a little lope to it, that's all. I'd pull one rod cap and look at the bearings and inspect the lifter bores for any rust. Any rust in there MUST be removed before you use it - and don't use scotchbrite to do it. use emery paper if needed. Rotate the shortblock to make sure the rings are not rusted in place. Give the rings a good few squits of transmission oil, then put it togeher with your parts. Degree the cam. Make sure to preoil it with a priming shaft not the starter, and rotate the engine by hand while you do so. Verify the oil gets up top, and then go through the cam break in process. Looks like a nice driver package overall. You'll basically have a 340 under the hood.
