Stop in for a cup of coffee

Yeah they are rare these days. Years ago my great grandfather flipped one into the river. This was back in the late 70s, they just left the thing in there from what I was told.
If he would have only known. The damn things went 40.
 
If you were going to put an overdrive of some sort behind my 408 SB, what way would you go?

I had designs on lighting up the pit this afternoon, but this lovely weather and the sparkling conversation here swayed me. Yeah Yeah I know .. What's so bad about 55* and 25mph winds? :rofl: I do think another adult beverage is in order.
 
What's the ratio?
TORQUEFLITE A727/A904 3-SPEED AUTOMATIC
Axle Ratio
4.56 4.10 3.73 3.55 3.23 3.08
Trans Ratio Final Drive Ratio
1st
2.45 11.17 10.05 9.14 8.70 7.91 7.55
Over
1.91 8.71 7.84 7.13 6.78 6.17 5.89
2nd
1.45 6.61 5.95 5.41 5.15 4.68 4.47
Over
1.13 5.16 4.64 4.22 4.01 3.65 3.49
3rd
1.00 4.56 4.10 3.73 3.55 3.23 3.08
Over
0.78 3.56 3.20 2.91 2.77 2.52 2.40
 
Yeah, the OD ratio is 0.78 so it really depends on the rear axle ratio as to suitability. Probably wouldn’t want to put one on a 3.23 rear.
