I don't know what kind of horsepower it makes because the engine hasn't seen any boost with the blower because of the 30 over pistons makes it high compression and I didn't want to blow it up. So after adding the EDIS ignition system with the mega jolt controller, I have control some over the ignition but you have to use the computer to set it up. I was running dual point. Mallory ignition in the beginning. It has a small bolt pattern in the front large bolt pattern in the back clear title and my name. It has a new Holley fuel pump 3/8 sending unit with a 3/8 return line. I'm just checking to see what's out there at the moment
