It is possible, but not something to do unless you like to constantly work on the engine.

They have to be set up in a rich condition for any kind of mid-range drivability (no acc pumps). And just about flooded (manually, with a squeeze bottle) with fuel to start in the cooler mornings (no choke action).

A couple of locals have had early setups converted to electronic systems. The old look with modern drivability.

You can also go with a Megasquirt system if you are up to building your own circuit boards..works just fine..I have thought about that for a 302 Ford and I did find the Hilborn plate and tubes at a swap meet but the guy wanted waaay more than I wanted to spend that day..

When converted to EFI they work nice otherwise leave them to the race cars. They are difficult to get to run so you could sit in traffic.

These use a positive displacement fuel pump. They depend on the varible pressure and flow. They use various bypasses and jets called 'pills'. Very simply, they idle and run full throttle by design. The sprint car guys make some changes to allow part throttle but it is still not a very streetable system.

EFI is the way to go if you really want one of these.
