408/ 904 trans

Sure it will usually “work”..... but why. If your making serious steam the low gear can and will make hooking on a marginal track more difficult. Something a points racer type person doesnt need or want.
It also widens the band between first and second gear. Some cars may not like that, compared to a stock gear spread.
Like i posted earlier, if you have a lower powered car, low gear can help get the car moving, same with a heavier type car with moderate power.
If car is light, makes a bunch of power, or both, generally the benefit is staying with a stock gearset
Low gearset is a bandaid.
I was tickled to find the trick Cope 904 tranny i bought on here isnt a low gear setup.
