the olds 455 is an excellent motor, makes A LOT of torque at low rpm's without much work. mine will be a mild build, 10.1:1 compression, .030 over, stock heads and a pretty decent cam.
mine will make 500+ ft/lbs of torque from idle through 3000rpm. Peak HP will be around 4-4500 rpm... not too shabby, since the rebuild kit for one is only 700.00+, and the motor cost me about 300-400 i think.
will be using a TH400 tranny, that's why I am asking if a truck 10 bolt is stronger than a truck 12 bolt, i'll probably twist one in half with 500+ ft/lbs of TQ
all Olds engines are the same width between the motor mounts, it is the deck height that is different, the big block is taller...
so same motor mounts for the small block fits the big...
depending on circumstances, may need to use the two forward holes on the block to mount the motor mounts.
can use car or truck frame mounts, just have to use the motor mounts that fit the frame mounts(they have to match depth of the motor mounts etc.)... and of course will have to set the engine in, and figure out where you will need to mount the frame mount, may have to drill holes, or weld them in.
in my situation, since my truck is all apart, i'll set the engine/tranny in, and make sure i have it far enough back so my driveshaft fits, then i'll bolt in the frame mounts, and tranny crossmember and i'll be good to go.
