72 duster 318 4bbl intake and carb recommendations

[Bennyc]

Looking to change my slightly bored 318 from a 2bbl to a 4bbl while keeping the 318 heads if that's even possible? If that's not an option I'd much appreciate any recommendations for any other build route I could take for just a street performer 318. Thanks!

I'm thinking an Edelbrock Performer but one not in production now. They did have one for 273/318 intake port size as 340/360 is larger on the ports. Maybe someone will chime in with where said unit could be found or maybe even a yet older Eddy unit. Looks like Weiand is in the same boat. For the carb, an Eddy 500 cfm unit. Be sure to get the Mopar specific throttle arm they say to use.
