lope rythym ?
hey guys, watched a ton of videos + had 3 cammed cars, all of my cams have been decent sized with tight lsa's 111-112
take this car for example, how does it have this "rythim" to the lope?

you can tell around 2:00 in the video its hot, and still has that chop, chop, chop sound? my cams are always just all over the place

Who did your tune? Maybe she needs a little tweaking. I've also had three "cammed cars" and they all sound similar to the video, the "rythem" is there. I've noticed that the bigger the cam specs with a 111 or 112 lobe tend the have more of a 'rythem" as well. My cars have all made between 400rwhp and 430rwhp. The higher the output the better the sound no matter what exhaust your running. The vette in the video sounds bitchin!
Try having it tuned again.

The newer generation of LS* cams seem to be migrating to this style of lobe profile and separation that causes this type of rhythmic cam lope. I personally think it sounds like crap. Reminds me of a Harley Davidson "potato potato" type of sound.
I like this style of cam sound much better.

ya that's how mine sounds, it sounds great, but no "rithym" to it,
i'm not sure if i agree 100% with johnny hardcore, i think its got alot to do with the cam. that cam in the video i posted is in sync. thats what i like, at least when i get little tid bits of it. maybe if my idled exactly the same constantly i might get sick of it !! ??

Don't get me wrong, the cam does make a difference, but the tune has a lot to do with how it sounds/runs as well. If there is a "miss" the rythem will be compromised. The lobe seperation will also make it more choppy but it with be rythmatic in sound. Mine have all had a rythem to them and don't have that chop becase they have all been average in size. Current cam specs 232/236/114. My 228/228/112 had a more choppy rythem but the sound was nice.
The vid of the vette that backs out of the garage sounds bitchin. Notice the specs on the cam. This is not your granpas cam in that thing. Thats a big cam making that beautiful music.
I think they sound better when they are bigger. I just wish I would have been more aggresive in my last build.
