Whats louder?

[86CutlassUCF]

I know exhaust matters a lot and this may be a dumb question but whats considering exact same exhaust what is louder and sound better a 403 or 350? im mainly considered more about sound so i was just wondering what would give me the that mean deep sound.

both have different heads, cams etc.

the head set and cam is going to make all the difference in the world ( exhaust and intake timing, duration etc )

if you are talking about stock motors- you need to see what kind of 350 motor and 403 motor and see teh castings- what they were in. the chevy 350 was used in 230 hp apps for pickup trucks and some were 350 in camaros etc. ya know?

From what I have heard, all Olds engines have a deep exhaust note by nature. I think there is too many variables to be able to say what would be louder.

Here is a sweet sounding 403, is this the sound you are looking for??

What engine do you have right now? Personally, I don't think there's enough of a difference between V8s to care. Anything 305 or larger sounds pretty good with the right exhaust. IMHO, straight pipes and glass packs make the car sound like it needs a tune-up. I always run Flowmasters because there's enough backpressure not to rob power and they sound great! I put a Flowmaster 80 series muffler on my Cutlass 307 and it's just loud enough to have a nice burble but not so loud that people think I'm a jacka$$ with an over-the-top unreliable muscle car. Just my opinion.

All Olds v8's sound nice and throaty. I have run 307's, 350's and 403's, all sound very similar. You definitely need headers and dual exhaust. Even the mild 204/214 .448/.472 cam adds to the sound. My 403 with 1 5/8" Sandersons, 204/214 cam and 2.5" dual Aerochamber exhaust with X pipe sounds mean without being too loud.
