When you build something that only has 300 cubic inches. It takes longer to make power and it will make less torque and it'll take longer to get there. When you build something with only 350 cubic inches, it will take longer than something that has 383 cubic inches. When you build something. It only has 383 cubic inches. It will take longer to make less power than something with 400 cubic inches or 420 or 430 cubic inches. Nothing replaces the efficiency of having a much bigger bore, and more cubic inches to draw the air in sooner and once the camshaft and cylinder heads are matched with the exhaust. The only thing holding you back is cubic inch.
