That’s what I have! It was a 318 ‘70!Belvedere before I put the ‘78 360 in it. I actually had to shim one mount with washers to go from the 318 to the 360 forward and back, not up and down. The casting ears on the block were different on one side between the two. I’ll wait and try them before spending a $100 for new ones. Thanks!Maybe not. Don't know what car you are working on. Is it the green '70 Roadrunner in your picture?
Reason I say that is years ago, I had a '70 Satellite with a 318. I pulled it and dropped a '67 440 out of a New Yorker in. It dropped right in without changing anything. We literally pulled the two bolts out of the mounts, lifted out the 318 & trans. Pulled the 440/trans out of the New Yorker and set it right into the Satellite and put the bolts back in. Only thing we had to mess with was the driveshaft.
