They are not identical but can be made to work. On a stock uncut crank you will need .030 over Chevy bearings. This yields .002 clearance. Iam using 6.2" small journal (Chevy 283) and 2.5 pistons in a 2.2. The part that is really different is the width. A Chevy rod is .940" wide on the big end and a 2.2/2.5 is 1.014" wide. That yields a total of .082 side clearance when using a Chevy rod. I felt like that much clearance wouldn't work too well. On one side, the Chevy rod is wider than the other, so I have welded up the more narrow side, and Iam in the process of reworking the welded side. Iam going to end up with around .020 side clerance. I can live with that! If I ever buy another set Iam going to call the vendor and see if they will finish machine a set wider. Everything else will work great on a 2.2. On a 2.5 you will run into piston height problems unless you can find the proper length rod.
