Hello all, new to this forum. I mostly hang around the the British MGV8 sites though I have watched this site for awhile now as I like to use the Buick 215 and 300 engines in my cars. Need some help with a crank id. Was digging through the warehouse and found 3 cranks stamped #135889. The main journal reads 2.5 inch. All 3 are the same. I’m only assuming these are Buick (300???) as I received a load of Buick engines and parts recently and the stamped numbers are within the Buick range I’m seeing for other 60s engine parts. Thanks for any support.
