Im installing a Weiand 177 blower on Chevy 350 engine, its in our -67 Impala SS. I have used E85 N.A. about 8 years, and will continue to use it with the Supercharger, its a Quick Fuel E85 650DP carb, i have a QF E85 750DP also, bought used, that i will maybe rebuild if i feel the need to run a larger carb. Keep in mind i live in Sweden, so parts and knowledge are not so common, even though Sweden is the Country i Europe with the most American cars. I have one issue right now, is it ok that the blower drive pulleys dont align perfect, its 0.08" off, the blower pulley is "deeper" than the crank pulley. Could i maybe just shim the blower pulleys out? Or is this not an issue? Its a 10 rib belt.
