Ok, a little back story :: About 8 years ago, (i was 13) when I first got into American Muscle, I would always think that a V8 with an aggressive exhaust note was stoked.....fast forward to now, I know that its actually more directly related to the camshaft. So here's my question, can a .....383 LS1 be as quiet on the exhaust as your typical 346 with stock exhaust and aftermarket catback? Like...a stealth stroker (minus valve train noise) I know a few of you may laugh, I'm still wet behind the ears

thank you

I'm not looking to build a stroked motor, just a question that's been bugging the hell out of me lately

The throw on the crank is extended in a stroked motor. But the reason most sound lopey is because the builder would throw in a cam. Went through the hassle to stroke, why not heads n a cam? But you can make a Stroked motor sound fairly stock. Close to a non stroker with rockers.

LT's, custom ORY w/ Flowmaster merge, 4in electric cutout and a stock catback and it will be QUIET until you open it up...

it's all about the exhaust if you want it quiet, lope is cam related.

^^ yep no matter what size the CI (cubic inch) is, it has nothing to do with how "loud" it is. The lope you hear is from the cam, you can easily throw in a baby cam and it sound like a stock LS1.

Take the 427ci ls7 Z06, it isn't loud at all and doesn't lope a bit .

I have a few customers running our LS2 CheaTR cam in their 383's. They drive and idle like stock and make high 400's to the wheels with AFR or other quality cylinder heads.

Thanks,

First off a "Stroker" has jack to do with the cam. You "stroke" a motor by lengthening the stroke of the pistons thus giving more cubic inches to the motor without opening up the bore. Cubic inches of a motor is measure in bore and stroke. To get an engine to have a choppy idle will require a cam but that has nothing to do with being a stroker.

I think its fair to say both is true. An aggressive exhaust note has mostly to do with exhaust/cam. But a larger displacement motor (given everything else is equal) is more likely to sound aggressive.

thats how mine is set up. 427 stroker nasty sounding w/ cut out open. sounds like a v6 with it closed.
