Re: starting line gear ratio?
guys, thanks for the input. the charts are very neat. very possibly the Dick Miller 11.25 # was with a torque converter [didnt say in the book] and when you ad in torque multiplication, it changes everything.
with mine,as is, at 13.69, its high from Miller and low for both the 2 charts. however, I will rather be under geared than over reved at the stripe. plus I could just gain more MPH if the engine will continue to pull. have to wait till Thanksgiving to run at Vegas [that just sucks-every track in the country is runnin' except Vegas] Thanks again, all.

Re: starting line gear ratio?
It was a copo with a 409cid LS. The explanation may not be up to your standards, but at least I understand the announcer when he says "this is a copo.

Re: starting line gear ratio?
Yes that seems very high.
Without changing anything, I would think it would like launching in 2nd much better than 1st gear. Stan |

► 5.83 * 2.81 = 16.3823 Looks good to me. That is just about 1% different than I calculate as a good starting place. Stan |
