318 Connecting Rods and Crankshaft

IIRC.... the Eagle cast crank have reportedly had some breakage issues in the past that the SCAT's have not had..... but who knows how the parts may have been abused. The OP is not pushing this engine so I'll bet you will be OK either way.

70aarcuda has used a number of SCAT cranks IIRC.

I have three guys who do machine work for me... none will recommend Eagle cranks or rods.

I'm no expert on balancing but many shops love the guys who are scared to death of not making everything exactly perfect. These guys have told me get all the rods and pistons close, send the crank to get balanced and run it.

You can get 150,000 miles or more out of a factory balance job. And those were rarely balanced closer than 20 or 30 grams.
