Engine surges

I hope someone will come up with some idea as to what my problem is. My 7.5 l Ford V8 runs ok at idle but when driven it surges and slows constantly. Full gas will not make it speed up, very careful acellaration will get it up to speed but it takes a long time and the constant surge continues. This happened overnight, the previous day I traveled 200 miles, everything ok, the next morning this problem started. I put dry gas into the tank, changed air filter, fuel filter and PCV. No change. Help.
