Aeromotive makes regulators for blow thru applications that work off a boost reference, or more simply put you run a little hose from the regulator boost port to a boost source on the hat or in the manifold. You can also use an MSD BTM ignition which pulls timing out per pound of boost, you can adjust the timing taken out per pound of boost from 1 to 3 degrees. Between the hat, 750 or 850 carb, and MSD BTM its less than $1500 and they work fine especially for cruising around and even work well in lots of 6, 7 and 8 second race cars. Now if you go with like a FAST EFI, full injection system, injectors, throttle body etc .... wooohooo big money, maybe $6k on up to over $10k depending on the injector size etc .... definately a much nicer and more tuneable set up but definately expensive and more times than not you will need help getting your car running right if you arent familiar with fuel curves and or computers.
