Both the frame pads and the motor mounts for 455 (430, 400, aka '67-'76 big block Buick) are different from those for the 350. I have never heard of a 455 motor mount that will work with a 350 frame pad in a Skylark/Special. I don't even think it is physically possible (without putting the engine too high). I have a '70 455 in my '69 Skylark. Pads and mounts came from '69 Buick Sportwagon that had 400. There are aftermarket people that sell the pads and mounts. TA Performance and Poston Enterprises are two I can think of.
Be aware that fan shroud and throttle linkage need to be figured out as well. Also if going with TH400 tranny, the kickdown is electric instead of detent cable, and crossmember is moved back, so emergency brake cable needs worked out, as well as driveshaft length.
You might consider joining the Buick GSCA. The clubmembers are some of the most helpfull that I think you will find.
Good luck!!
