I'm sure there's a US company that does a 3.2 M20. Metric mechanic or something like that.

You cant 'stroke' to 3.2 you would need oversize pistons too. Unless you know exactly what the crank is you cant put a value on it

Any markings on it? Somewhat doubt it will be from the metric mechanics kit. My money is it being from an s50b32

yes S52B32 and M54B30 cranks. stroke length is 89.6mm

most 3.2L arent 3.2L they are 3.1L

Ireland Engineering also sell stroker kits but i would think you could source parts individually for cheaper
