I would like opinions on a cam to go with, I am looking to get an Explorer motor with gt40 heads and intake. I can get a E303 cam for about $100 but it says to go with a higher stall convertor than stock, right now I am limited on funds so I can't afford to get a different convertor, how will it work with a stock convertor. I could just install the stock 5.0 HO cam from my old motor and save some $$, this is a daily driver that won't be raced, just need to replace a motor that started smoking last fall before I put it up for the winter.
