M1 Sb intake. Best for small blocks?

Two things stand out to me the 323s and what I am assuming is a stock converter if you went to a 355 rear end ratio and a 3,000 stall converter you would not believe the difference out of the hole. The hotter camshaft you have combined with a high-rise manifold are actually not really benefiting you with that setup it doesn't start to come into play till around 4500 from there on up is where it will pay dividends tire size also comes into play
