Ok so i need some input and advise. I just picked up a 91 bronco with 351w
Have a guy at work that swears no power can be made on speed density so i want to prove him wrong. What are some good budget mods to make power? I am about to do 4.10s and have a glasspack muffler(it was free) on it already.

I talked to my Mustang tuner shop about doing something with my speed density 5.8L 95 F150. He told me that without a MAF conversion, not much could be done. You can probably get away with simple cold air kits, underdrive pulleys and exhaust after the converters. I realize that won't gain to much though.
