273 upgrade to 4bbl?

@BPTracing I just bought one of those intakes like you posted the pic of in post # 7. It's a nice intake and it has the small ports. You can't beat em for the price! Next best choice would be an Edelbrock Performer, but I would find a used one if you have time to wait on one to pop up. You'll have to re-engineer the transmission kickdown linkage no matter what you use...or run a Lokar cable. Good luck to you.
