WHAT WOULD YOU DO ?

Most likely it’s a 3.79 stroke. That’s a way better stroke than the 4 inch arm anyway.

Like I said, I’ve never seen an economical 3.75 stroke crank.

Is it 8 bolt, 6 bolt or dual pattern?
haven't taken the flex plate off yet but it has 6 bolts I am also happy to see the crank was drilled for a 4spd
