would a mass air flow conversion be a good idea on a 86 5.0?would there be any benifits from it or power added or loss?
not worth doing the cam on the E6 heads. plus you would have to go mass air if you did. you are changing the airflow charcteristics of the engine out of the range of the stock SD ECU.
just tried to answer you other post. Change the whole intake. The most restrictive part will wind up being the lower. If you don't want to change the lower right now change the upper to a later 5.0 intake lit has a bigger inlet runner and a 55mm tb. You can probably get one for free if you ask around get the egr block and throttle body at the same time. Other wise pick up an explorer intake or if you have the money they make really good aftermarket intake for a mustang. Is it still speed density?
