340 Stroker mainly for street, what gear would you run?

With a manual trans;
The goal is to get a starter gear of just around 10/1
3.55 w/ 2.66 low manual trans =9.44
3.23 x3.09= 9.98

With an automatic and 2400 stall;
She might get away with 10% less so 9/1 target;
3.73 x2.45=9.14
3.55 x2.45=8.70
3.23 x2.74=8.85

With a 2800 stall, you can drop another 10%, so say 8/1
3.23 x2.45=7.91
2.94 x2.74=8.06

However; the lower the OVERALL gearing is, the lower will be your rpm at the top of second gear, at 60 mph. So not much of a problem for a stroker if it overpowers the tires. But if the tires are married to the road, then that will slow her down some.
Take for example; 2.94s x1.45 second gear(A727)=4.26, and 60=3070/zero-slip with 28s, say 3500 on the tach @15% slip.
Whereas; the 3.23 x1.92second in the manual trans =9.98, will get you 60=4470 with the same 28s ..........
Never having had a stroker, I can't say exactly what rear gear to run, but I can say that the 3.55s with the Commando are a dynomite combo...... until you have to cruise for hours at 65=2770....... I installed a GVod to drop that to 1940
