Any pics of what the OP's car looks like? If it's "stock-ish", then the blower under the hood maintains that appearance. The extra weight of the big block will likely change the handling characteristics of the car on the street, if that's of any concern.
FWIW, I checked out the specs of the blower mentioned and it says it needs "premium" grade fuel; does CA 91 even qualify?
Our gas is crap, worse it the winter. We are at sea level and have access to liquid power adders and have blended a few types of fuels before, so I don’t think that will be an issue.
