I ordered an Eagle 10350375057I cast 3.75 internal balance 2pc rear seal crank in March (Summit) and now they're telling me August... maybe.

Scat does not make an equivalent piece.

The specs are not negotiable... I already have the 2pc seal block bored, do not want forged, do not want external balanced. Must be 3.75 stroke I already have the rods & pistons. This car will not be raced. (looking for torque, not horsepower)

Anybody know where I can shop for one of these from a different manufacturer?

stroke
rod length =5.7
basic engine family
(part numbers from most manufacturers),( or the the part numbers by major listing suppliers who may change them,)selling the products, tend too brake down in some manor to indicate some logical index, to be able to track and inventory them, the fact that you, or I may have no clue as to what it means without some experience dealing with those numbers is not that rare, if you buy enough parts from enough suppliers your may notice those numbers eventually start to make some sense at times but at other times they appear to be almost randomly snatched out of thin air by a guy on an LSD TRIP swatting imaginary flys on a key board with a hammer.
Eagle 10350375057I
Eagle 10350375057i

I build mostly BBC chevy engines and use mostly SCAT forged rotating assembly's look over the part numbers youll see some eventual logic to the part numbers ]
