Bill..the carb reponds to what ever is below it in n/a form.Do you have a stock 283 sbc or a max effort 632 bbc?I only ask..because if you place an 1150 dominator along side a 600 vs on the work bench,they both flow the same.Nothing.Both carbs require a pressure drop to operate.Whats your powertrain combo and vehicle weight?
