Motor mount question for engine swap.
 
My dad is building up a 455 blocked motor for his 64 GTO and is confused with which motor mounts he needs. I told him to match them to the block and order 455 mounts. He thinks he needs to match them to the Chassis of the car. Who is right? :confused: Thanks in advance guys.

Motor Mounts
 
I put a 455 in my 66 Bonneville and ordered the 66 stlye mounts. The 455 block has additional mounting boses cast on them to accompany any stlye mounts. Fix'n to put a 455 into my 65 GTO, same deal applies.

Buy engine mounts for a '64 326 Lemans or '64 389 GTO. Actually the '64 -'72 A-body V8 Pontiacs all use the same engine mounts, except for the odd-ball 455 mounts which you don't need to install a 455 in one of these cars.

I know this only because I have two 1964 Pontiac A-bodies (a GTO and a Tempest) and both have 455s swapped in.;)
