A popular gear for a 383 SBC and 700R4 are 3.73 gears. I personally run 3.42s with my 355 and 700R4. Mine is strictly for the street, though, so I went milder. It's nice to travel on the freeway with overdrive and 3.42s. They feel almost like the 2.73s I had originally.I have a 1973 chevy nova with a 383 stroker motor I want to know what is the best gear to run for street and strip with a 700r transmission.
