I'm building up a Burtz engine with his cam, flywheel, and high compression head. I'll likely use a Leonard Nettles oil pump, but plan the rest of the internals to be pretty much stock. I will initially use the standard manifolds and Zenith carb, but am seriously considering upgrading to a Weber and possibly a header down thee road after I get it running satisfactorily.

Is it worth going the extra to an Aries "high performance" muffler over the stock? If any of you fine folks have the Aries "high performance" muffler, how much louder over stock is it?

Any recommendations for timing gear, since that seems to be a weak point that would logically be even more vulnerable with the increased hp?
