I've been reading on here about how people are running faster with 3.23's than with 3.73's. I'm worried because I will be ordering 3.73's. Now my question is this: These people that have seen this, were the TPI setup's stock? Cause I'm running a superram with some decent sized heads. Wouldn't 3.73's benefit me more than 3.23's? Thanks!

The SuperRam isn't really TPI. It's a SuperRam. It has some degree of higher RPM capability, and therefore does not suffer from the same trade-off that costs TPI any chance at producing power above about 4500 RPM. So that doesn't apply in your case. Your car may benefit greatly from the higher # ratio.

With the SR, go with the 3.73's. If you had a TPI unit I would advise against the 3.73's.

I had a semi stock 305 with 3.73's. Best thing I have ever done to the car was get the gear. You get really good acceleration and still good top speed. I cant see how 3.23's would be better. I used to shift the 305 at 5000-5500 rpm. It never lost any power. Good choice of gears.

Whatever gears you get, I would stay away from Richmond Gears. It doesn't matter who puts them in or how good they are put in, they have a greater tendancy to whine. This may not be the case for everyone who has Richmond gears but I have seen too many cars with them in there that whine.

i dont believe that all richmond gears wine considering i've put 2 sets in and neither have wined. what does it matter if they wine anyways? they are a lot better than others that may be out there. i would rather have good gears that in some situations may wine than ****y gears. just my opinion.

The metallurgy and gear tooth shape on the Richmonds is purpose-built for drag racing. THat's why they tend to whine. They also tend not to last very long on the street because that's not what they're made for.

If the car is a daily driver, don't use the Richmonds, you will regret it in a year or 2. If it's a trailer queen, then don't use anything else.

can always compromise and get 3.42's, i am getting a set some time in the near future.

they only wine during break it like all gears. They are strong gears and good quality. I have them, have no problems, and they dont wine.

Then mine must still be breaking in.....after 10'000+ miles. I don't think so. Most Richmonds do whine but the are very strong. When you run a 10 bolt with good power you want the strongest gear you can get. Hate that whine though

errr im putting in some richmond 3.73s but now youve got me worried, its a daily driver! i dont care about the WINE its what somone said "dont last long on the street.." Well thats all I Do is on the street!

WHy will the richmonds break on the street?

danzig27

I'm going to use GM Motive gears. Haven't heard too many complaints about those.

whoever keeps saying they will break on the street doesnt know much about richmond. they have pro gears, and it states "takes the severe shock and punishment that is required in drag racing. not for the street or any other form of racing." richmond street gears,"are designed to hold up under the rigors of EVERYDAY DRIVING as well as take the punishment of diabolical race thrashing." so whoever keeps saying dont use them know what you are talking about. if you had a set break on you then you probably didnt break them in right or you rode them too hard too often or something, whatever, but they have street and track gears and pro drag only gears, check it out. before you diss something read up on it. the quotes on these different gears were taken right from richmonds add. my friend has been running his 4.10 richmond street gears now for almost 4 years and he is at the track every weekend and street races whenever with no problems. i had a set of 4.56 richmond street in my 92 5.7 camaro for over a year and a half with no problems. i installed both neither wined. and neiher broke.

Most often when people say "Richmonds" they're talking about the first kind, the purpose-built drag racing ones. You're right though, it would be better to be specific, since they do offer a street gear that's essentially equivalent to any other good-quality street gear such as Motive, US Gear, Precision, etc.

And the Pro ones don't "break" on the street, they just wear fast.... street gears are hardened as hard as they can be hardened, to make them wear resistant, but this also makes them prone to shatter under shock loading. The Pro gears are nowhere near as hard, so they stand up to the shock, but they wear much faster as a result.

It's a matter of design for a purpose, rather than "quality" as such. No one can question that Mack makes a good truck; but you wouldn't use one as a limousine, now would you? Any more than you'd use a Cadillac to haul a load of gravel. Each has its purpose, and works well for that purpose, but is unsuited for the other purpose.
