The 302 is ready to drop in my 37 Chevy truck,well, I still have to haul it out of the cellar and out to the barn as soon as the glacier retreats.
The GMC is about 1-1/4 inches longer as measured from the rear mounts on the clutch housing to the front mount.The actual overall length is about the same as the 261 engine the truck had,so much for the long motor business.
This is a few shots of the front mount I made, simply welded a stock mount cup to a piece of 3/8 plate steel to locate it foward.Drilled a few holes to fasten to the cross member.Then with the mount mocked in place,I drilled down using a hole saw for bolt clearance.
New mount A few more holes
