Motor Mounts BB vs SB for a 69

[mike16]

I dont know... but there is a spacer that goes on the driver side of the engine block between the motor mount and the enging block........on corvettes in 68. if your application calls for a similar spacer the are available repro through corvette vendors.

on 67 and 67 big block camaro's the BB and sb frame mounts were different. header manufacurers requested chevy do this. it placed the bb about 1-2 inches over compared to sb's . this allowed header manufacturers to make bb headers that did not requir radical bends and gave enough clearance for pipes and engine rocking motion.
