My best mod was making the restrictor plate for the EGR. It cost me nothing but 20 minutes of time. The engine runs much better and for the first time I have felt the torque the six is supposed to produce. Much better mid range power. Up until making the plate I wished I had 5.0. After I swap 3.55 gears for 4.11's I think I'll be really satisfied.

I would have to say the best mod for 1986 and older 300's would be switching to dual exhaust. I did that and a 4bbl intake and cam upgrade and still almost doubled my gas mileage. Best $120 I spent. (well more like $700-$800 after exhaust, carb, cam, intake, etc.... but just the exhaust will do wonders)

shotgun, how do u make an egr restrictor plate? id like to try it.
and as far as the duel exaust i just have some questions? like how did u run, it mine is a 95 with 2 maniflods, what type of setup did you use , how big of pipe, and most important can a 300 6 sound good? i really would like a deep sound if i put pipes on it.
thanks,
Evan

So far, I would say ALL my mods. The cam woke up the engine when I stuffed it in...but the 4bbl and the header WOKE it up big time. I have to be careful now when pressing the go pedal.

Evan: Remove the two bolts that secure the EGR to the intake manifold. Carefully remove the old gasket. Use this as a templat and trace the outline of the gasket and bolt holes on a piece of thin stainless steel. When finished your restrictor will be just like the gasket, except solid.
Trim the outside of the plate with a pair of tin snips. Drill the bolt holes out with a drill. Use a little silicon sealant (form-a-gasket)to get a good seal. Slip the plate in place of the gasket and reenstall the two bolts. Go for a test drive and see if it runs any better.
