Hello guys, I am looking for advice about an intake for my 273. It was originally a 2bbl but now runs an Edelbrock Performer carb on a stock intake from a 69 340. I am running an XE262H cam and Summit Racing ignition. If I could come up with a 273 Commando intake and maybe a 4 hole carb spacer what good/bad changes should I expect? Is it even worthwhile to change intakes? Basically, I am just looking for a little more get up and go. Thanks.
