Its a 3.75 stroke, & the serial number says 35450 on the front, just wondering which one this is, I got an engine assembled with it in there, Callies doesn't know because they lost a lot of their system info due to a hard drive failure, any help would be appreciated, I'm trying to find out which Callies crank this is, thanx.

Matt.

 

If it was a "Stealth", it would look like this
