Hello again just looking for some feed back on the Holley 4000 I am about to start to rebuild one but I have been told it "WILL SET MY CAR ON FIRE ' looking for some pros and cons thanks 

Reading back over all the post I can relate to everything Florida Phil wrote. I am new y blocks but have been fooling with Chrysler engines and GM for a long time . I do remember not wanting to touch the anything to do with timing fearing the engine would never run . My timing light wiring always seemed to wind up on a exhaust manifold carb return springs were made of rubber bands. Engine flush worked well until all the crud washed into the pan and starved the engine for oil. I am just rambling.
