aluminum pulleys?
early c4
anyone running aluminum pulleys? like march, zoops, summit.
what is the deal with the pulleys for corvette costing so much more than others? (corvette tax i guess)
anyone have any experiance or advice on using pulleys from a different application, lets say like camaro pulleys?

The early pulley is just a pulley, not part of the balancer. I have the aluminum March set and like them. The cost is reasonable for the two piece aluminum with steel alternator pulley. If you get the three piece set with aluminum alternator pulley the cost goes way up for some reason.

I'm using a march ud on the crank and alt. The water pump is a asp racing pulley and std. rotation (all are allum.) w/no problems. I am currently waiting on a lightened p.s. puley.
The clearance to the crossmember is what I see becoming the issue when trying other crank pulleys.

I run the March underdrive pulleys on my 1985 (had to look yours up) same as yours. You would want to run the three set pulleys so that you spin the alternator at the same speed. Without the alternator pulley many Forum members have experienced a drop in voltage output at idle. This seemed to be especially true when their cars had additional add ons that pulled power...amps etc.
When I added the March set of three...the alternator output actually went up.

Remember that the reason for running lighter pullies is to reduce the rotary inertia. When you reduce mass from the innards of the pulley, though you can cut some overall weight you have very little effect on the rotary inertia because here it's the mass farthest from the axis that contributes most to said inertia.
