SB to BB swap on my 74 3/4.....same motor mounts?

[chev406]

My truck was originally a 454 but I had a small block in it for the last 4 years or so. I'm ready to intall the 454 again, but don't remember if I had to change motor mounts or not?

My neighbors are pricks even though my yard is well maintained, so I'll have to make this swap quick! A delay would be bad news, and leave me vulnerable to attacks from the county! I have to be stealth.

motor mounts, engine bracket, are the same on 74.............right!

Thanks!
