camshaft IDLE differences
Let's say you had a 224/224 .560 114LSA in a camaro/firebird/corvette.
Let's say you have the computer all tuned "correctly".
Whatever the loudness of your IDLE is, let's call that BASELINE.
Let's say its 70db for example and MILD lope.
Something that lopes SLIGHTLY let's say.
Now let's say you switch to a LARGER cam, say
a 232/232 .560 114 LSA in the same car.
Let's say you have it tuned again, "correctly".
What would be the difference in IDLE loudness?
Maybe only a small amount, like 5db more than before?
What would be the difference in LOPE?
Maybe a small amount, barely more than before?
Maybe a medium amount, noticeably more than before
and most people would mistake your car
for a "race" car.
Maybe a large amount, and there is no doubt
anyone on the planet would know you
have a "race" car.
I'm just saying "race" car as a general term anyone
in the PUBLIC would know what I meant.
I've reasearched the different cams using the SEARCH functionality
but no one actually COMPARES what I am asking about.
I'm trying to figure out "how much difference" there would be
between a "small" cam(224/224) and a "larger" cam(231/237)
at IDLE.
Driveability goes to the 224 I know that from research. Some
have said it drives as well as STOCK. I haven't found anyone
that has said that about a "larger" cam like a 231/237. However
I would be willing to listen to anyone who can claim the driveability
of their "larger" cam is just as good as a "small" cam. If that's
the case then why wouldn't eveyone go with the 231/237
since the only differences left would be MPG and HP if driveablity
were equal and IDLE equal.
I'm stumped.
thanks

a 232/232 on a 114 lsa really wont be that much different than the 224/224...
lsa magnifies lope much more than duration in my opinion...
lift seems to change the sound of the not the lope...if that makes sense...
going from a 228/230 .571 .573 112+2 to a 232/240 .595 .608 113+4...
the lope interval (time in between exhaust pulses) stayed about the same...but the way it sounds now is different with the added lift...it sounds more aggressive, while idling about the same...
the new cam sounds a bit tougher than my old cam, but not because of more lope, but the exhaust sound is sharper...

Interesting question. I'm not sure the bigger cam will be louder.
A choppier lopier cam might sound louder but maybe it's because the lope is more pronounced.
