ok i know i've seen this in here before but has anyone put a flame kit on the exhaust of a fuel injected 300? if so is the kit worth getting or should i just rig it my self? right now i am running duals with a gutted cat and 18inch glasspacks on the ends of the pipes.

 

You should search for flame throwers. Its been discussed many times, and some of the threads lay out the proper way to design them yourself.

Don't waste your money on the kit. The electronics of the thing can be purchased for around $20, or scrounged from a scrap yard for nothing. You'll need the following:

Coil (two for dual exhaust)
Spark plug & Wire (two for duals)
Condensor (usually near the coil on older engines of from a lawn mower)
Standard relay (horn relays are better but a standard one works fine)
Toggle switch
Push-button momentary switch.

These parts will get you a spark plug tester. Installing it into the FI 300 will do you no good as the amount of fuel in the exhaust is too low to ignite. The kit you but usually cuts out a spark plug or two and allows more unburnt gas into the exhaust. Unfortunately, it allows more unburnt gas down the cylinders and into your oil as well, significantly reducing the life of your motor. And that's not good.

I have my homemade kit installed on my 78 F150 460 4x4 and it does work. I have to pull the manual choke all the way out and pump the gas to get it to flame up, and I only get 2' long backfires as opposed to a "flame thrower" effect.

It's being removed as the risk of damage to the engine is too great for the little effect I get. That is until I get the fuel injection system installed.
