Complete 6 pack find- not mine

Big block setups are fairly prevalent. Small-block setups are much harder to come by, at least the intake. I would discourage anyone from getting one with old carburetors unless you're trying to do a restoration that you feel calls for that. It's challenging enough to have a six pack set up and running correctly with new carbs
I see BB intakes all the time new for 3-400 dollars on E-bay. Dang small block ones typically bring $700 and up for a used one.
