Howdy, Installing my 455 into my 68. I bought replacement motor mounts and don't have no bolts. Could someone tell me the bolt size and length? Also what is the bolt size going from the frame mount into the engine mount?
Thanks Steveo

I can fish out my bolts I used for my 68 /w 350 HO. Are the the same mounts?

Assuming a 68 400 is the same;

The two bolts for the motor mount to the block: 7/16"-14, "semi" castellated, 11/16" head. Not sure of the grade.

The frame mount to motor mount: 1/2"-20, 3/4" head, grade 8.
