Would i need a 650cfm carb after installing a high rise intake manifold?
327 sbc .30 over solid hydraulic flat tappet 552. camshaft stock gm heads with bigger valve springs for cam. It had a edelbrock performer intake with a 600 cfm carb on it then i switched to a stage 2 summit high rise intake with the plenum wall milled out and a 1 inch spacer. My truck wont start after doing that just pretty much flooded my engine

It's all jet size and powervalve, also make sure your float level is sorted, then just swap jets eg bigger/smaller, and powervalve to suit timing
