For those of you in the garage right now...

What is the diameter of the register for an 8 bolt crank?

Thats the last bit of info I need before I place an order for a new one to be built..

Thanks

I.D.,O.D., or both?
I think I have a 8 bolt Ohio stroker crank in a motor in the shop I can use to make those measurements from luck
Or do you want a stock street hemi cranks for those measurements?

i think all the modern V8'S are the same. You may run into something different with an old poly or 1st gen hemi. Of course you didn't say what engine you were asking about.

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
