Steve, you read a lot about people venting their bellhousings to help cool the clutch and evacuate the dust. Is this something you recommend?

If the car is a dedicated drag car venting the bellhousing MIGHT make a slight difference to the racer looking for a few tenths. But to be honest, any serious drag racer running a clutch is likely going to replace it pretty often. In a street car, no way would I vent the bellhousing. Way too easy to get road debris in the clutch assy.

The clutch is 6 years old, he's not the original owner, he bought it used, and he's put 3,000 miles on it... that said, there's no telling what was done to it before.
What I do know is we stopped selling those because the price for manufacturing that friction became so expensive it would have made a $1000+ single disc clutch, which isn't going to work in the market. The friction itself is fantastic and very very smooth. As with any aggressive metallic based friction, if you get it hot enough it will liquefy and adhere just like this did. It doesn't make it a bad friction, but I would agree that this isn't the unit I'd have recommended for a cam only Fbody.

I know many of us are guilty of going with the bigger is better theory and that it does not always mean that it IS better. There are a lot of people on here that don't need a stage 3 but have one anyway and sing its praises. I hope I will be singing as well, as I have a stage 3 waiting for me to install in my garage. In all fairness I did not contact you before I bought it. Are you saying this is a BAD choice for a car that is more on the mild side?
It will occasionally make rubbing noises if you keep trying to feather it like a stock clutch, but if you beat the **** out of it, it behaves. I used to get complaints about it chattering when (wife/friends/body shop guys) drove the car and the engine was mostly stock, but as the engine has gotten stronger, the complaints have died off mostly.
Is it a BAD choice for a milder car? no. is it the BEST choice? probably not.

On all the situations I have seen, it is usually the opposite scenario. A clutch rated for 500 hp is put into a car making 800 hp and the clutch slips and becomes overheated or glazed. Doing the opposite...putting a clutch made for a 800hp application in a 400hp car just gives you a sore leg from the added clutch pressure and a bit more grabbing due to the heavy pressure plate and aggressive clutch material.
This is what has me scratching my head on the clutch in the picture. 3000 miles, very little heat checks on the flywheel, and we have a melted clutch. Granted we do not know what the previous owner did, but with 3000 miles and it worked fine, I would guess it wasn't overly abused.

I would not worry about it. This isn't like a cam where you bought a massive cam thinking that you were going to add heads, higher compression, headers etc, but you did none of those and just crammed the huge cam in your stock engine.
