1987 f150 engine preformance
 

hey im wondering if there are any good engine modifications for the 300ci inline 6. i do have a budget so im looking to get the most bang for my buck. i can do some custom work so dont be afraid fo shoot my some ideas. i havent done any other preformance work on it so its still all stock. anything would be great!

thanks you! :)

New intake manifold, exhaust including headers, cam, then a tune. Not exactly too cheap, but really the only things effective. You can also just tune up the truck, to restore lost power. I would start with that first.
