Cab I apologize I never saw it. I posted there first cause I wasn’t sure then saw the engine forum and moved it

AndyF one question I have. I believe I just found the article or your dual quad build. Also testing a single 4 intake that made more power. One thing that caught my attention was the 12.1 compression to make that 615hp. Don’t believe that will work with 93 lol. Wonder what horsepower loss would occur with just 10.5 or whatever can be run on pump gas.
