Re: BBC with SBC frame mouts vs BBC mounts
JB, The Big Block frame mounts will roll the engine to the passenger side about 1 inch at the carburetor stud. The transmission crossmember must also be changed and that will move the transmission tail 1/2" to the passenger side and 3/4" forward. The rumor that the 302 sits lower is not really true. The 302/350 frame stands were to allow more room for an 8" harmonic balancer at the sway bar. These mounts moved the engine slightly back and if anything, slightly TALLER, than the 307/327 frame mounts.
