does the f-303 or x-303 require mods to the pistons for valve clearence? reason i ask i might be picking up a 93 gt this weekend if everything goes as planned, and im going to start ordering mods. :SNSign:
the F-303 wont cause any clearence issue's and is a Great basic High performance cam----the X cam will cause piston to valve clearence problems on a stock engine----hope this answered your question-
Just a word of advice. If you don't plan on changing much else but the cam, don't put in an F or X cam.....those are for cars with aftermarket heads/intake/exhaust/gears. If you put it in a stock engine, it will be a dog and give you no power....just worse gas mileage.
