69 valiant 273 suggestions

I find all this very interesting because I have a '69 273 in my '65 Barracuda that I plan to swap for a '70 340, but before I do that I'm switching the intake to a 273 commando 4 bbl intake with a '67 AFB (I think it's 500cfm) and I hope to get some better power than I've had up till this point (up till this point it's had a 340 intake with a large AVS carb and it hasn't run right, mostly because of mismatched ports I believe).
