I am going to build my own intake for my gmc 302. It will be a mild build with headers, cam and maybe lighter pistons at some point, manual trans all in a model a coupe. I love the howard 5 carb intake that uses 97's but is this the best carb to run? I want the intake to have provisons for 5 carbs but run on only 3 with 2 as dummy carbs. I have a bunch of rochester B's laying around but not sure how they are performance wise. 97's are just so damn expensive for even a core carb so I'm not sure if I should run my rochesters of something else. Carbking will hopefully jump in here. I also have a couple of zenith one barrels which I think are great carbs. Please advise.
