I have a 1990 F-150 with the ford 300 inline six. i want to milk some more power from it but cant find any websites or catalogs to find parts for it. I was woundering if anyone new of any websites or anything that would help me out.  

i am only 17 and am just starting out so if you could help me out that would be great  

I think Clifford has parts or offenhauser for intakes and a few cams to choose from also.   WIEDER  

Picked the wrong 300 post first.   WIEDER  

Comp has three cams in their catalog for the 300 I-6, I'm sure there are more out there. One of hte best thigns would be to see if you can find a hydraulic roller cam for your 300 I-6.

Quite a few drag racers have been running 300 I-6 motors for a while. If I remember correctly, roller rockers for a 5.0L Windsor will work on a 300 I-6.

Your next best performance moves are in the exhaust. See if you can find a good exhaust header for it. From their, a good exhaust system.  

thanks for the help
