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

[Coupelx]

Everything is 'built' now days. everyone who can spin a wrench is doing a "build".

I purposely avoid using either build or built for that reason, separate myself and what i can do from the cookie cutter cars.

So they're rebuilt to custom spec. 'Built' just seems like an overrated, overused word to me, in regards to engines.
I've been here long enough to remember that achievement in r3v patents. ;)

Built would be when you actually stripped it down and had proper machine work, then reassembled while taking measurements and checking clearances.

There is so much more to it than just slapping it all back together and crossing your fingers. So yea, "built" is in a different class than assembled. Anyone can purchase new parts at factory spec and slap it together. But if you are going for high horsepower, then hoping for the best just won't cut it.



On another note, maybe I do cast my own parts. Haven't you heard about that zero lag turbocharger?

[Fusion]

I do what I have experience with or I'm comfortable with, leave the rest to people who know what they're doing.
I'm not questioning someone's ability to do so, I admire build threads here, but does the whole world need to know by reading a sticker?
Linguistically, is a 'built' engine one I replaced cams and injectors on or one that was fully taken apart and rebuilt with new aftermarket parts for higher power?

[Exodus_2pt0]

Bullshit.

Many people can and do assemble an engine, properly building an engine is a whole other thing.

Kind of like when someone offers to rebuild an auto trans and says "Yea there's nothing to it!" I always run the other way.

Hell, I went to Nissan Technical school to become qualified to rebuild their automatic transmissions, and I haven't rebuilt a single one since. Just not worth the hassle to me, because it is so far from "nothing to it".

Why is an engine 'built' rather than 'rebuilt', 'custom', or 'upgraded'.
All engines are built.

Always lol'd at the 'built not bought' slogan too. Like did you buy the cam or make it yourself by pouring moulten iron in your garage and then lathing it to spec?

/rant, thanks for your attention

Do you do your own work? Or do you pay someone else to do it for you? Not talking shit, just an honest question that could shed light on why you feel the way you do.

Also, Molten.

The sound has more to do with firing order and degrees of rotation between firings, their V8's fire at every 90 degrees.

This made me chuckle. You should hear a 60* V6 with a bit of work done to it even with minimal overlap lope and rumble at idle.... LOL I have seen an LQ1 throw a fireball out WG loud pipe about 3 feet long when the the throttle plates slam closed...

Firebird knows exactly what I am talking about..... ;)


Lopey Cam is the song of high performance no more no less, sadly I have been away from such things so long, I feel as if I have forgotten it all

[rturbo 930]

The Camaro sounds like it might actually go somewhere if you put your foot down. The 540i just sounds lame.

Love a lopey idle. My Z has a cam in it. It has a lumpy idle, but runs smooth overall, and really comes on after 3000rpm. Just wish I had a decent car to put it in so I could let it stretch its legs.

Not mine, but it has the same cam, and similar work done:

[george graves]

Well crap. I guess I need to turn in my "man card". ;)

[F34R]

I had a cammed m20...it was not much fun down low, but mid to up top it was INSANE! Lumpy cams= fun!

[JasonC]

LSx's have kind of a higher pitch sound to them, I prefer the deeper traditional sound of the older V8s. Don't get me wrong, if I here a LSx come thumping in, i'll turn my head and smile ;D






With 4 poppers and 6 bangers, i'll still be grinning if they are cammed up. Even my Corvair has a small cam



When they are smooth and quiet, it's kind of boring to me....

The M30 is God's engine.
