I'd have to say go with the 2 or 3 chamber flowmasters. I have a set of 2 chambers on my big block now and they give it a great throaty sound. I had a set of 3 chambers on a 327 in my first Chevelle and even those gave it a good sound. Good luck with whatever you decide
yeah, flowmasters sound awesome! I had them on my stock 2bbl 350 and they sounded great. if they sound a little lean on the 283, get a set of 4" exhaust tips, they make the sound much more throaty. my car would pass for a big block. it sounded a hell of a lot better than the 396 i have now pumping through stock exhaust.
My 65 has flowmaster 2 chambers with complete 2-1/4" system. Also has Hooker competion headers. With original 283 it was louder than I wanted it to be but sounded great. Now with new 300/350 target engine it is louder still. I like the sound but if I had it to do over again I'd go with the 3 chambers.
I've got a built 350 with 3 inch pipe and 3 inch, 3 chamber Flows, with no tail pipes...
If you want LOUD and mean, try that!
One problem... don't do it, it's TOO loud.
I'm thinking about that 2 1/2 inch Flow. system.
