Well I have an oppertunity to aquire a 455 from a '72 Buick and would be interested in squeezing it in my '67 Skylark that currently has the 300/300 combo in it. How much trouble am I asking for if I can talk someone into helping me out with this request? I understand that my year of Skylark came with a big block option. Not of course the 455 but I think it had the option of a 400. :confused:

You can buy the motor mounts from either TA Performance or Poston, and the 455 will fit . The 67 GS had a 400 option, and the 455 has the same exterior dimensions. I would advise a tranny change also, as the 300 won't handl big block torque.
