Hey guys, I need some help. Ill try to make this as short as possible, I changed some parts and now Im having some problems I cant figure out . I have a Merc flat head, stock cam, Fenton twin carb intake, Holly 2110 carbs, Mallory unilite distributor, MSD 6200 box, Looks like MSD coil too. The car had a alternator on it when I got it, What I just did is, I put a Isky 400Jr cam, Isky springs, changed the lifters, valve job, Put a Eddy Meyers intake, soaked and cleaned the carbs, I actually re-routed the fuel lines from a inline T to a fuel block . I took off the Alternator and put a Generator and regulator on, Problem is, its acting like a electrical brake down around 3000 RPM, it runs great up till then, Not sure it is electrical, but sure feels like it. I clipped my volt meter to the battery lead on the regulator, and grounded it to the engine and ran it inside the car so I can see it while driving, when it starts braking down, volts are around 13.9 give or take . I thought the coil may be braking down, so I changed it with a stock coil I had laying around, didnt fix it. Id appreciate any help ... Thanks ..
