I have a 92 Z 350 TPI, I just got my march power and amp series pulleys, the crank and alt pulley. I have no smog and I cannot find out anywhere what size of belt I need. I have e-mailed march, and other performance shops and also posted topics on my local f-body site, no one can help me. If anyone out there can help me out with a PN or size I need for a 6 rib belt please do, I've have these pulleys for about 4 days now and I am getting VERY impatiant. Thanks for ur help.
