I have about 80 dollars to spend in jegs on my 1988 ford f-150. It's from a Christmas deal...long story. Anyways, what is the best way to spend it??? I was wanting to know if I would tell a difference with underdrive pulleys. I can spend a little bit more money than that but I do not have alot. What about a throttle body spacer??? k&n air filters to make a homemade fipk??? I would just like to know the most efficient way to spend my money and get something that will make a difference. If it matters I have on what to get for my motor it's a rebuilt 302 with the biggest cam in it without messing up t he computer, roller rockers, headers, roller cam, etc.
Everything you mentioned is a waste except the K&N - but don't try to do a FIPK. The straight drop-in gives you the best performance & mileage increase. Then insulate the fresh-air ducts from the grille to the throttle body. That'll cost about $50 total, so you have $30 left.
