Gearing
« on: September 23, 2013, 08:43:48 AM »
I completed the manual transmission swap in my 79 Formula 301. I put in an ST-10 from an 81 Canadian Z-28 with the deep 3:42 first gear to make up for the lower power of the 301. I left the 2:73 rear end gears in to see how the combination worked, and it is weird. The tall 2:73 gears make the car start rolling under a load, and the car seems to accelerate fast at low RPMS, but you miss the power curve of the engine. The car drives fine, but it is like being stuck in overdrive (the one good outcome is that the gas mileage is great). I picked up a set of 3:23 rear gears to try out, I figure that should give me a good combo for the car, I want to get decent acceleration and not kill my mileage to bad. I think anything higher than 3:23 will be taxing my 301 a bit, any thoughts?

Wow, posted for a week and nothing but crickets...
I guess I'll go it alone.
