Talk to Jake Raby or you might throw your money away. The cam has to be chosen based on intended use, fuel system, valve sizes, head work, and several other factors. That is why Jake has such a large selection of cams. But then you need lifters to match that will not fail in 500 miles. This is another place you cannot cheap out. Do it wrong and you may need a whole new motor. Search the threads on lifters and in particular ceramic lifters.

Can't do much with stock injection...web has a cam (or jake) that has a bit more lift...that's about it.
Beyond that you need carbs or aftermarket FI (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) |

In order to keep the stock FI, you are very limited with the cam selection, I think Webcam #73.
Jake might have something, but don't expect any miracles with a cam that is stock FI freindly. Ti valves are race only for the most part, and if you are complaining about $900 carbs, wait till you see the price on that other stuff. A 3-angle valve job wouldn't be a bad thing, it helps whether a stock rebuild or modified, it just cost more in labor. |

I have roller cams and lifters, BUT no way are they are gonna work with any variant of the stock injection and they don't jst drop right in without all the other components in "the combo"..... The benefits of a roller cam are mostly in the fact that the valve as fast as possible, alowing more charge to enter the cylinder, thus increasing power..
My 9550 and 9010 cam are designed especially for stock injection systems....But you won't make more than 115HP and if you make it bigger than 2056cc you are taking risks. Used carbs don't cost 900.00 |

Stay far,far away from the roller rockers for any street engine that does not run an external oil delivery system...And even then about 95% of TIV cams, (all of them, no matter the Mfr) have characteristics that do not compliment any greater ratio rocker arm.(ramp rates too fast)
The roller lifters and cams have already made their debut in certain "Super hero" engines, as early as July 2004.... Just getting more time on them before selling them to guys like you! Oh yeah, and developing combos for them that kick total ass.. |
