Carb whipple 3.3 or billet high helix 10-71
Getting close to making a decision on blowers for my 10.0-1 tall deck 572’s with promaxx 317 heads flow 375 at 650 by Valeko, 254 264 .632 .632 112lc. Keeping compression where it is and switching to e85. Will probably set them up run 900-950hp for now but would like the ability to turn them up and run 1050-1100hp. I have read till I am blue in the face and have read about several marine engine builds that have achieved 1050hp on the carb whipple 3.3 and the 10-71. Which one is the right choice???

E85 has had no effect on aluminum, stainless, rubber, or steel braided line that I have it soaking in for 3 years. There is a lot of mis conceptions about E out there. I have a guy on our river who has been running it for 10 years and does absolutely nothing different than if he was running gas. And has never had a single issue due to running it. He has a blown 25 Eliminator Daytona with aluminum tanks. He doesn’t even drain or treat the fuel in the fall. Just winterizes it and back it in the barn.

if height is an issue then the whipple all the way, serp belt vs cog, for slippage, if your maxing out the 3.3 then 10-71 for sure..........Screwed vs Blown....

One thing that will suck is range. You can make some inexpensive high octane gasoline by using 100LL and adding an octane booster with lead. You’d be getting better fuel economy in that scenario. But the ethanol is probably still makes more power on a blown app.
