Actually did that to a point but the calculator numbers to input are in my head.
336 is a given to make the math work.
336 X gear ratio X MPH divided by tire diameter = RPM
So I was running at the track often and the math there put the torque converter slip at worst summer heat at 10%
So You must add 10% to the final number to get RPM If the RPM in the equation was 7000 then add another 700 for converter slippage.
Other than that the math was straight forward.
336 X 370 X 176 divided by 31" = 7058 Now tire growth at speed is a factor also.
I was running 31 tall Hoosiers on 8" rims at 150+ expect 5% to 10% growth.
Say 5% so add 1.5" to tire diameter. 6732 RPM then the 10% slippage = 7405 RPM I ran it to 7600 RPM and quit looking at the tachometer in high gear 1:1 ratio.
And looked up in the rear view mirror and seen my buddies headlights dip down from him letting off the throttle so I backed off also.
It pulled to 7600 in first gear and I went to shift and shifter was in a bind and did not go into second but I was not letting off as I was in front.
I kept pressure on the shifter and seen 7800 rpm and quit looking, it shifted and second gear did the same thing.
I quit looking at the tachometer at 7800 again and it finally shifted..I was thinking that tweaked Yamaha V-Max will pass me any second.
He topped out at 147 and I was 3 school bus lengths ahead and he said I was pulling away like he was sitting still.
That short block is in my 57 chevy and just the other day I let a friend drive it and he can't shift and it went to 7800 RPM.
It has seen 8500 2 times..Knock on hard wood that 350 is holding together.
Oh that nova was not a stock body or suspension deal either.
