The frame from ANY GM A-body of the same body type (2-door, 4-door, etc) will bolt right in because they all use the same frames. So a frame from a Chevelle, Tempest/Lemans/GTO, Buick Skylark, or Cutlass will fit. Any frame from 1964-1967 will work. 1968 and later frames won't work because the wheelbase changed in 1968.
factory rated at 390 hp gross
The same as you do in the 1968 Buick Wildcat
YES,All 1968-1972 gm a-body ( cutlass,chevelle,skylark,gto) can be interchanged.
