Anybody switch from standard 727 gear ratios to 904 1st and 2nd ratios and improve your et?




Without any info it's an impossible question to answer. With info it's a 75 post re-hashed arguement.


'66 Coronet, 3650 race weight, 446ci, 727, 4.56, 30x9 radial slicks - best of 10.58/125 @ 2100ft. 60ft 1.45 It was a pretty simlpe question and others were able to answer - just asking if it worked for them. Nothing to argue about either. Thank you to those who chimed in.




First, according to your INFO, your car would probably benefit from the low gearset, if the car would hook. Your 60' is a tad slow for a 10.60 car; if it's spinning now, the low gearset will make it worse. Second, it's a SIMPLE question with a COMPLICATED answer, since heavy, low horsepower cars benefit more than light, high horsepower cars, and since there is no set formula that is avalible to make a choice, it's an opinionated guess at best. Since most of the posts didn't give their combos, how do you make an accurate comparison them to yours? And the arguement? There has been more posts on here than you can count debating 727 vs 904, low gears vs high gears, 'Flite vs'Glide than I can count, usually ending up being little more than typing practice, since the only "right answer" is the one that works best for YOUR COMBINATION (who would have seen that coming?).

Bottom line is, there are a lot of posts on here that people ask Q's and don't give enough info for anyone to make an EDUCATED reply. Without knowing engine specs, no one can suggest a cam (although many do). Without knowing car weight, engine specs, trans, gear ratio, etc, no one can give good advice for a converter (although many do). The more good info you give us, the better info you will get back. Some of it might even be RIGHT
