So i just bought a 1979 motorhome with the 460 and the guy that sold it to me said it just needs a new carb because it runs really rough. once you start pressing on the gas it will only go about 30 miles an hour and the motor shakes really bad. so im kinda lost because i have put on new carb edlebrock 600 cfm, new distrubtor, new vac advance, new fuel pump, new plugs wires, went throught the entire vacumm system and no real change. so what now please help me out thanks |
