Can I use the slant 6 / 318 gear set with the 3.09 1st gear behind my built 340 stroker motor?
I want the low 1st gear to offset a 3.23 rear axle ratio. Tranny guy was questioning if the gears were as strong as the 2.66 or 2.47 gear sets. Will they hold up?
I did that for my 64 Dart w/a modded 70 340. I dropped the clutch at 5-6k rpms for about 50 runs at the 1/4 mile dragstrip. Best run was 13.09 @104mph. 3400# car, never had a problem with the trans anyway.
