400 block motor mount compatability

[rrTor-Red]

Thanks Wild. I like the idea of the 470. Should be enough room for a half inch pickup. 4.25 stroke might get a little tight and require an external oil system. Good info on the true of the cranks. I've got a lot reading to do.

Mine is a 400 stroked to 470

The 77 400 I pulled from a van ran like a scalded dog in my 70 Super Bee.

To the OP-

Make sure your balance is correct with respect to the crank and the trans converter.

I did not the first time and ended up with a vibration that started at 60 MPH and didn't go away until 120!

Nice. That combo has real good geometry.

Thanks very much. The people here are great. Lots of knowledge being shared. Real cool. I run a 4 speed with a 4.56 rear gear and about 29 inch rear tire.

might want to check into flywheel balance as well, then.
