1971 Chevy revs too high again!!
You guys were right I strobed it for the second time and didn't notice I was seeing two marks and not one. I was reading double. Problem is the tac reads double. Are there adjustments for the stock dash board tac? Looks like I have 4 10 gears. 2 complete tire revolutions resulted in a little over 4 drive shaft revolutions.
