Blueprint crate 408 long block- combos?

With the crap that passes for gasoline these days, and how quickly it evaporates, I'd use an electric fuel pump just to reduce cranking time at start up. That being said, I have had no problems with Holley mechanical pumps on a 383 and a SBC.
I'm glad you brought that up. BP recommends 91 octane fuel. Here in the crap state I live in, almost everyplace has 10% ethanol fuel. The gas station I go to has non ethanol 90 octane that I use in all my small engines and my classic Buick daily driver. I have to figure out if I'm going to go with the non ethanol 90 and add octane boost, or the premium fuel from the other stations that have ethanol but are 91 or 94 octane. I HATE ethanol, it's hell on small engines and carburetors.
