As far as the speedometer is concerned, a few years ago, I changed transmissions and the linkage was in the way of the speedometer drive cable. Bought a kit with a small sensor that is attached to the drive shaft, which is sensed by an adjustable box with a cable to the original speedometer. It is more accurate now than it ever was.

And like Mick, every test I ever personally conducted, a carburetor got more power and better economy than efi. Just cannot get the carb to compete with the efi for emissions.

But your vehicle, your call.

Does the blower help with the altitude problem?

Old enough to know better, too young to resist.
