Shift light, tach, by ear, rev limiter; what's your choice

Shift light!! Let me say that when I raced my mid-12 sec 69 Charger, it was always a tach. No issues, easy peasy...the car was just a gentleman going down the track. Set the tach red arrow at 6200 and shift it there.

Then 30 years later, I built the avatar 408 Demon. I thought I would shift by the tach in it too. OOPS...big mistake. First, the car leaves pretty hard, MUCH harder than the Charger and its 4260# of girth ever did. 1.51 60' was its best last year. Second, the TC stalls right at 5000 rpm so a shift is due really quickly after leaving. Need to find the best shift point but it's somewhere in the 5900-6300 range. Foot brake car so you just stanbed the gas and get thrown back, the front end is up. and you cannot be looking at a tach!! You have to have the light to tell you when to shift. I laughed at myself the first time out...there was NO WAY to look at the tach. The shift light was ordered and installed before the next weekend when we took the car to the track again. The shift light made it very easy to know when to smack the Cheetah shifter.

Now there are LOTS of people with cars way faster than mine on here, let's hear some more from them!
