Making power out of the 318

Dan the man said
It affected by the gear ratio. If you change the final gear ratio from say, a 2.76 ratio to a 3.21 and you don't change the drive gear on the speedo cable where it goes into the transmission your speedometer and odometer will not work correctly. Guess I'm wrong here too

you're not wrong, you're just floating around in the non-sequitur lagoon matey.

the correction that the speedo gear makes is about the furthest thing this dude should even be thinking about at this point.

it has no bearing, effect, matter of importance or offer any issue in any of the following: building his 318, swapping in a magnum, selecting and installing a transmission.

this is like worrying about if the cigarette lighter works in a car you're going to buy. a benign issue that is not pertinent to the matter at hand.
