Well two factors here; 1. The tach is not working and is getting replaced soon. 2. I can't get to 60 mph. 50-53 mph is tops then it just runs out of power.
On a slight incline up a hill, I have to shift down to third gear just to maintain enough power to go about 35-40 mph.
Another issue is the carb setup, while the weber is better than the stock carb it still starts hard at high elevation (I drive in elevation from sea level to 9,000 above SL), will die on steep hills, ( I don't want to constatnly be rejetting) plus it won't Calif smog.
