Open motor turning more produces more horsepower too. Ive seen several dyno pulls using crates versus an open motor. Difference can be 100 hp plus. Ive done some research on the crates versus open and thats why i said what i said. Take a massaged 355 versus a crate and throw them on a dyno. Turn the crate 6200 and turn the 355 7300 and see what happens. Big difference but to get that 355 to make more horses means spending more dollars which is why my point of a rpm rule. Nice 355 will make great horses at that rule and be equivalent with a crate motor.
