GM Hot Cam use these days This cam has been cursed & belittled seems like forever. If it's so bad, why does GM continue to use it? I've read up on it on a few posts, & the people who have one get descent track times seem to love it. Just curious. Not trying to start a forum riot over this.

The term "better" has too broad a definition to toss it around like this. What is better for a given application depends on the car's intended use and owner's priorities. And it's a fact that everything is a compromise.
The GM hot cam gives up some net power in exchange for less valvetrain stress. That's the design compromise. It makes great power in the midrange but gives up power at high revs. And it's sourced through a mass production supply chain, so it costs less than smaller-volume aftermarket parts.
If these are your priorities, it's a good choice.
If the car's owner has different priorities, wants more power and doesn't mind spending a little more $$ and changing valvesprings more frequently, it's true that there are better choices.

Therefore, making this statement (and with spelling and grammar that wouldn't pass the 6th grade) only reveals your lack of knowledge on the subject matter at hand.

Ahh, the eternal dilemma!
It is all just a matter of basics. Most male genders are hardwired to think that if their "shlong" is bigger, they will have or make better sex.

Yep not everybody wants or needs the newest Donkey Dick sized cam with a cool name that they saw on Teh intrawebz. The hot cam and the ASA cam are both good choices to make more power on the cheap and they are mild enough not to require machining the heads to accept a double spring. Keep in mind also that not everybody drag races. Their are some road race classes that allow a cam change but require homologation so the cam must be from the OEM.

I agree, there are different applications out there to suite a variety of folks. Not everyone needs or wants a wild MS4 camshaft. Besides some of the bigger cams compromise drivability and risk emissions.
These GM cams and the "Smaller" cams are designed to give the owner a few extra ponies to their stock vehicle. Alot of high duration, high lift cams usually require deep gears, good intake, and headers to really perform.

Mine has been in since 2003. Made 381/373 on stock heads. Peak torque at 5000 rpm peak horespower at 5950. I liked that it was easy on springs and I did not have to spin the hell out of the engine to get soemthing out of it. I haven't been to the dragstrip since 2005. I mostly just drive the car for enjoyment, and like having the extra power. It has fit my purposes.

theres a big difference between a giant cam and a hotcam. If you want added performance and a smallish cam a tr224 kicks the **** out of a hotcam at all rpms, and is pretty small compared to what most people dd nowadays. Nothing wrong with a hotcam, but for the time and effort involved why not put something in you wont want to change in a year
