Have you tried budgeting out what it would cost to do a 451 instead? You're already buying new pistons, so scooping up a used 440 crank shouldn't add that much to the final total and gain you 50 cubes!



That would be my pic, But i'm sure a mild 9.1 400 with all the bolt-on goodies will scoot along real nice.
