motor mounts

The july issue of Hot Rod has a good read on BB motor mounts for the 73 & 74's. Shows difference between SB & BB. Anyone considering a swap might want to read it. It does make a difference with header fitment.

Hey toolman, I don't think you can see current issues on-line. It was in the "pit stop" section if I recall. Yes the mounts are available, I got mine from Advance. Made in the USA believe it or not.

I ran SB mounts on mine for years, never knew there was a difference until I replaced my headers. (My car was originally SB) I went with a larger tube/length header and they would no longer fit. I swapped out the frame mounts for the correct BB mounts and all was good. It raised the motor a good 1/4" or so. I ended up removing the lower control arms to get to the nuts inside the frame holding the mounts on. You might be able to get to them with the LCA's in place but it would most likely make you start swearing. I replaced my LCA bushings while I was at it. they needed to be done anyhow.

Ok good to know, I am bouncing the idea around of putting in a BB in. Yeah I changed my lower mounts when I put my sb crate in, switched out to polyurethane. With the motor out it wasn't easy. I spun the bolts with the air wrench and put side pressure on them until the nuts caught and spun out. Even more fun getting the nuts back on the new bolts and tight.

I've done motor mounts several times with the motor still in the car. It is a pain but I found that even with the lower control arms installed it can be done. Obviously easier with 2 people. I found that if you use a long, single piece extension (not two extensions together because they will fall apart and cause more frustration) and use a swivel socket on the end. Not a swivel with a socket on it but a swivel with the built on socket. So, just 2 pieces. An extension and a swivel socket. I also like to put a couple wraps of masking tape around the swivel portion so it doesnt flop around and it would be easier to "adjust" to get in there. Its not too bad of a job. Just have to get the right angle.
Just my opinion.
