We run in a hobby stock class, someone told me that a company named fast gear makes a 3:55 rear gear for a 7.5 chev rear end, cannot find them on the web, any help would be appreciated.

Have found a supplier www.fastshafts.com for those of you that may need to know.

I found 3.42 and 3.72 for the chevy 7.5" case but not any 3.55's. The only 3.55 ring and pinion I find is for a 8" Ford. I use a 4.10 in my 7.5" hobby stock and run it in second gear (TH350) on a 3/8 mile track. Some of the other hobby stocks at the same tracks use a 6.0 gear (9" ford) in high gear. One last thing the gear ratio your talking about would be 3.55:1 not 3:55.
