Running a 406 SBC on A half mile track.
1.75 second gear * 3.25 ford 9" = 5.69

Question is when I go to the 3/8 mile track, what are your preferences change the tranny or the rear end gear.
Do I put in the 1.84 Saginaw,
Or a 6.00 rear pig.

myself i'd go with a 6.20 in the rear end and a 6.0 for the 1/2 mile in hi gear

Its nice since your running a 9in to have another 3rd member set up and just swap them out and if money permits its nice to run high gear and have the final in the rearend.But on the 3/8s I think I would look at 6.20 to 6.50 depending on how many RPM you want to turn and as usual its just my opinion.....Towman
