New from mancini there like $200 for a 904, $400 for a 727....
I got an '84 998 that has them, I'm contemplating if it would be worth it. If I rebuild the 904, its going in w/ a 2200 stall converter...

I put the low gears in my 904 (thanks Stricnine!), but they honestly didn't make my car any faster. In fact, I couldn't even tell much difference. If you have to pay for them, I would stick with your factory gears... Maybe others have had different experiences. I ran the car in the 1/8th before and after the switch and got identical e.t.'s

I would say that with your combo the low gear set would work well. Would give you better low end grunt on the street and the 1-2 drop can easily be covered by the engine.

So what years of 904s were the low gear sets in?

The 2.74 1st gear set first came out in 1980 in certain models. 1981+ all 904, 998, 999's had the 2.74 1st and a 5 clutch wide front drum. Most were lock-up converters. John

I got my low gear planetaries and sun gear from Neal Chance Transmissions here in Wichita.
It was a good used set and I paid $50.

A good local transmission shop should be able to help you out.

If it's a street car or you're on street tires at the track with limited traction already I wouldn't bother with it. It's not worth the time and effort.
