Got ripped off. Looking for a new idea for the inside of the engine. Stroker maybe?

Build what you got, that convertor isnt the best for a stroker, neither is it for a turbo. It sounds like a fun N/A motor. May not even have to bore it, just rings? turbos make torque low so you dont want alot of slipping in the convertor, and that cam sounds made for your convertor and valve work so I'd run with it. Headers help.
