Can someone explain to me the attraction of a lumpy cam?

[graveshaker]

I personally love the different sounds of engines. I guess that's why I own German, Japanese and American.
Here is my Mustang Popping popcorn.......


And the rumble of my boxer.....

Only listening to the sound, I think it sounds like crap too.
Like a beat down engine that's about to die.
Probably because those lumpy came guys run super loud straight pipe and that
by itself sound stupid. You better be making like 600hp at least.

I have a friend who got a cam for his his el camino.
He was pissed! There wasn't a lump to it, then got a SHIT cam
that made it barley idle and his car is still slow as balls, but he's happy because he Just loves that sound. blah.

s65 sounds like a lumpy cam big block every time I start it up.......kinda cool, but it very awkwardly immediately turns into a normal euro idle after about a minute. I'm not an engineer, but I've heard it has to do with emissions and heating up the cats.....maybe someone can correct me if I'm wrong about that.

I've experienced something similar with my m20 on really cold days... Sounds like a quiet muscle car or a diesel or something but then it goes away by the end of my street :(

I agree completely with on that. My dads friend Scooter Patrick use to race Can Am and was a semi works driver for Porsche in the mid to late 60"s and raced Can Am to 1975. He said it was the best years of his life racing in that time period. He also raced for James Garner in Formula 5000 and in a Lola T70 i think that was the name of the car.

That's awesome. Here's a pretty cool documentary on amazon prime of Garner's racing team from those days. Scooter plays a huge part in the team.

Dang, my m20 could use a tiny bit more lope.

firebird I am going to have see if I can the vid of my brothers LQ1 at the very end of his dyno pull last year. That netted 496 to wheels on 10psi with the exhaust cam on the front bank running 4-6 degrees advanced......... Its built for pushing 2bar....

The thing is...most of those cars are piles of shit that people abused. It sounds like a bad running on with a swiss cheese exhaust and THAT is a sleeper!

This one is rather obvious :p

I take back what I said about "nobody suspecting a thing" with that car, John. Anyone who hears that is definitely going to suspect something.

You know the BBC engines in these Can Am cars went up to 9.3 liters in displacement and 1000 hp in there final evolution !!!!
