Hi every one Ive A 1985 F-150 i picked up a 1995 roller block to build to try and get just a little more grunt out of my truck. Here is what i have so far and what i am hoping to get . I have the roller block and all its parts. i have a set of gt40p heads i have a edlebrock performer intake and a edlebrock 750 dbl pumper carb. i am only looking to may be get 300-350 hp and 400 or more torque . so what cam and other internals should i look for?
