One of the main reasons I did my 107 build was to address all the weak points. The crank was the biggest one.

I don't think the crank is your biggest weak point...

Huh??????
I changed out my cylincers on 88, to get ro 98. I then bored the orginal cylinders to get to 95.

I did not do a crank swap to achieve 103. Decided you keep hoping it up going start chasing weak link. Mechanic friend talked me out of it, said I should consider beefing up tranny. I rebuilt tranny with stock components.
