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.

I agree,mine slowed around a .10-.15 when I took the low gear set out in a 9.30et car.This was the only change made was convinced by others it would go quicker with stock ratio.....WRONG.

LOL, I have heard that a time or two. I need a lower gear ratio as my car too heavy

Thanks for the input, you have very valid points there. I have been contemplating putting in a low gear set for a few years. I'm freshening my trans and I think I will try it. I run caltracs w/monoleafs along with their shocks and 5 inches of susp. I'm pretty confident that I won't have traction issues - there is only 1 way to find out right? Thanks again

My GTX was a solid 12.3 car when i changed and went about a 10th faster after that maybe a tad more. had gear out and when car was 11.00 to 10.9 put it back in and it was again a good .10 to .15 better after the change.
Nice increase through first and second little bigger drop off to third gives some back
stock
2.45 1st and 1.45 second
low set
2.74 1st 1.55 second.

Good luck with your project! Unfortunately, it is a lot more expensive to put the low gear set in a 727 than a 904; they start out over $500 at A&A. 904 low gear sets are dirt cheap, being OEM in about 15 years of cars and trucks.
