Low gear set in a 904

I am going to freshen my 904 and I am thinking about putting a low gear set in it. Have any of you done this? Did it lower your 60' time? Was it worth it?

Currently my Duster has a fairly mild 360 and the 60' is 1.60. I am hoping to get it a bit lower.

In your case it should help your 60' times, and is an easy swap. There has been many threads on this - might I suggest using the search for earlier posts?

Something to consider is,is that no. on the et slip worth the expense in a low performance package? There are other was to lower your 60's wothout that gear set. What is your current combo? Those gear set are not cheep.

You don't have buy a after market low gear set there are plenty of stock low gear sets out there just have to find them. I would do it in a heart beat. Worked great in my car all the way down into the low 10s. Cheap way to get a lower powered or heavy car moving without putting more gear in it.

I bought a 2.74 sungear and planetaries from Neal Chance Transmissions for my 904 here in Wichita for around $60.00 a few years back.

It was a street car that I took to the strip on occasion and I never noticed much of a difference.

It wasn't worth the hassle IMO., but might be in your application.

I did notice a differance in my car with them, I just had a 318 and 2.76 gears.

They are not really expensive for a decent used set. I would not pull the trans apart to add them but I would sure as the world spend a few bucks to put em in if I had the trans apart already.

Not only are the lower ratios to help get the car moveing they are much stronger than the normal ones.

I used to have a few sets, I don't remember if I sold them all or not, I will look tonight. PM me if your interested in one.

The 360 makes about 400 HP. It has an 8" converter that flashes at 4500. Rear end has 4.56 with a spool. Cal Trac bars, monoleafs and Rancho's. Tires are 29.5X9. I have 5 1/2" of front end travel. I have a set of 4.86 gears that I can put in the rear end.

I am going to freshen the tranny because it has plenty of passes on it and I don't want to take a chance on breaking it.

On a related note does anyone make a 2.28 first gear for the 904? I am pretty sure that Pro Trans does but I was thinking that A&A might too but did not see it on their website?

Every A&A Catalog for the last couple of years says

"Straight-cut 904 Gear Sets" Call for Info

I'm going to take a WAG and say, Rick probably didn't see the need
to tool up for these, since Pro-Trans already makes them.

I'm sure it's an expensive undertaking and probably just buys them from Dave Smith.

Again, just a guess.
