To get out of the minds "318 vs ***", lets look at a single cubic inch. 360 per say. Some build them to shift at 7200 rpms all day and do it going 11's in the 1/4. Some build them and shift at mid 6k and run mid 9's. Why would that be?? Because it's about how well the heads are flowing, and a cam to match, and a intake/carb to sit on top of it that compliments the design of the build. I bet my 318 makes more power at 5000 rpms than a stock '73 340, and I have less of just about everything. Why would my smaller engine make as much or more power at the same rpm??? Is it my smaller valves? Or less compression? I don't say this sarcastically, I say it because there is a theory that one HAS to spin the daylights out of the smaller engine to make equal power. Simply not the truth.
