That is hilarious.

Here's a reality check: a good NASCAR motor will run you upwards of $50K, and 
it will run in the 8 to 9K rpm range for at least 500 miles.

>>>You made an astute observation about your car's existing exhaust--it 
sounds like a boat.   In fact, it sounds almost *exactly* like a boat, and nothing 
like an exotic Italian car.   That's one of the main reasons I hate that 
exhaust (although I freely admit that it functions well enough in terms of 
delivering horsepower).

ANSA exhausts can be power-robbers (although apparently much can be regained 
by modifing them internally), but they sound totally different, and better.   
Good enough for me to forgo the extra power (at least for the moment!)

Your throttle response probably won't be markedly different with Webers 
versus a quality carburetor or fuel injection setup.   That is (to a large degree) 
dictated by rotating mass.   Lightened bottom end assembly 
(crank/rods/pistons), skeletonized aluminum flywheel will let it zing like a superbike.   However 
it will be much more difficult (perhaps even miserable) to drive on the 
street.   

Cars have flywheels for a reason, you know....

As to your mechanic, well, if he genuinely believes that simply changing 
rocker arms and lifters will instantly enable you to turn 9000 rpm on a stock 
bottom end, then it's time to get a different mechanic! :>)
