I hate to disagree, but I transplanted a 455 into my '71 which originally had a 350 and I did not have to change the frame mounts.
Just get the motor mounts for a 455 equipped '71/'72 LeMans/GTO and it will slide right in. Oh, and some things to think about: 1. The trans will need to be changed to a TH400 and the associated driveshaft. 2. The original radiator for the 350 was only a 2-row, (3 row for A/C cars) so a 4-row radiator will need to be substituted. 3. The factory 2-into-1 1-3/4 inch exhaust will have to be swapped to a set of duals. 4. The electricals will be the same, and the A/C will bolt up fine along with all the original accessories.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
