Hey guys, well I finally got my truck back from the manic mechanic that held it hostage for 2 months...

I have been having a blast with it and have a laundry list of upgrades (tow points, skid plates, etc etc)

I wanted to start thinking about what I can do to increase the power of the rebuilt 302 I put in. Its not lacking power really but a little more never hurts.. :)

But on to my question; What should I be looking into to increase horsepower...
(no silly tornado comments pls :p)

A new y-pipe with a high flow cat made the biggest difference on my 302. I would also look into an electric fan swap.

thanks for the info, and while I am thinking about it, what exactly is mass air?

i would get myself a set of shorty headers, a new y pipe, and lose the cat if the state was cool with it. then i would hit the ignition system up with a cap, coil, and ignition module. jacobs, mallory or msd, i would also do a kn filter cone swap for the stock airbox.
you will notice a big difference after that, not huge, but you'll feel the grand you just spent.

FullSizeBronco.com sticker will increase HP by at least 25.


Hey, he said no funny tornado comments, nothing about stickers.

The ignition stuff totals up to $120.00 (from Summit) and is CARB legal and should be done immediately so you start saving money with fuel savings to pay the $191.00 for the all states legal Catco Y-pipe and cat.

Forget the shorties (read other threads why) and forget the cone K&N and just pick up the $40.00 K&N drop in filter.

Do all that and you're legal and up quite a bit of throttle response and mileage in my experience and your wallet is only lighter by less than $400.00.

Follow this thread, save some money, gain some power (and mileage) and save me from carpel;

Don't worry about mass air until you plan on doing a really big cam swap, or a big head change. Search for mass air and you'll find all you need to know, including facts that say for a new engine, you don't need to worry about it. The only thing mass air would help with (on an engine that doesnt have a big cam/or head change) is an aging engine.

Hey Six,

I followed that link and looks like some good info. I am not running a bronco, I have an F-150 pick-up with the fuel injected 302. Its an 86. I have a brand new oem coil, wires, cap, and plugs. My question is, if I go with the MSD brand ignition components on my engine, will it make that much difference over the brand new oem stuff I now have? I am getting approx 16 mpg right now, if I install that, gap my plugs to .055, and set my timing to 13.5, do you think it will get me closer to 20 mpg? I drive 90 miles a day right now and can use all the help with fuel milage I can get. Thanks..

I'd bump the ignition and love your 16mpg

Much depends on older, dead or dying ignition parts. Try the plug gap, but if you don't get a jump in performance, consider at least an MSD coil.
