Is there any where that one can see what parts interchange without having to go to the salvage yard for their Hollander manuals? I would like to plan my engine swap and see what I may need to make the change over go more smoothly. I want to remove a 301 2V and replace it with a 1978 400 4V in my '77 Catalina Safari wagon.

Are the engine side of the motor mounts the same between the two? I know I will need new frame mounts, but are the buckets on the block or will I have to find 400 ones?

My next concern would be the exhaust manifolds. Are all 400's of this vintage the same, or will they have to come from a B-Body?

Thanks for any help
