Thanks Guys..

This is for a BBM wedge motor, it will have a (Chevy) PG trans, TC and Flexplate, so I think I only need the OD of the register...

The previous build had an Ohio crank in it, but we kinda destroyed that when the motor locked up crossing the stripe at 7300 rpm.. so sent it off to the recyclers..

I think I can live with the 2.14" number

So thanks again
