Carburetor Question - Is this a good call?

Honestly. if I were you, keep yours eyes open for someone selling a Carter or smaller eddy cheap.
Makes things simpler and they all can be made to work well. It would be a nice option to have choice anyway.
That said. Factory smog era (some '67, all 68 -9) carbs are a little more involved. So those have a little steeper learning curve - especially with a non stock engine.
