Richmond Gear Set assume 3.91?

[340six]

Mid 2004 I had my cone (Borg Warner ) rebuilt (machined and shimed
Bought a new install kit ( bearings crush sleeve)
And new gears. They don't have a size. Roll past 3.5 times and right past 3.75 but short of 4 trips. So assume are 3.91
Anyone cross reference this? I know it was before August 29th 2005 been packed away since.

Not sure if this can help........

Gear Tooth Ratio Calculator

Crawlpedia's gear ratio calculator will find the ratio of your ring and pinion gears as determined by the number of teeth on each gear.

Gotta count the ring teeth and pinion teeth.. Divide pinion count into ring count for ratio
