Here is an old top loader spread bore holley. R84014-1 0665 The primaries,
secondaries and choke open freely. As you can see it has vacuum secondaries.
I was told it is a 650 but would have to run the numbers to make sure.
Would make a cool old nostalgia carb. $40.00 plus the ride.
I also have some Thermo quads $20.00 ea. plus the ride
