273/318 Offy Dual Four Barrel intake

no..not without modifications of the mounting holes

Hmm, ok the 64 273 heads have a steapear grade where the head and intake meet up.

1965-1969 273; 318-340 all bolt together the same way. Only difference is the intake port openings on 273 and low compression 318 are smaller........

Not sure why the mounting hole would be different
