Not worth the $$$ to me, had them on my 1990 & was glad when I removed them. Volts would go up/down all the time. While driving at night, you could see the lights dim considerably while at a light. Just my .02

if all you want to do is reduce pully drag on the motor .....i would have to say go electric

electric water pump and cooling fan and mayber get a belt that eleminates your ac compressor ....if you want to run your ac just put the belt on if not dont

I had a march under drive pulley kit and on my 83 gt stock it did seem to help the top end a bit. On my 351w the pulleys made a he'll a difference but caused the motor to overheat so I got rid of them.

i have u/d pulley's and i can see the lights dim at idle.but i needed new pulley's cause mine looked like crap but i would rather have the stockers.

ALMOST STOCK

In the 10 + years I've ran the March Performance Power and Amp UD pulleys and still running the stock WP and ALT; I've never had a issue with either an over heating or a charging issue.
