hey i just sold my cam still attached to the head from my 2.3 Ranger to someone for his 86 SVO 2.3...its a roller cam, thats what he wanted. he didnt pay me yet so how much should i ask him for it?
The cam is not so much a big performance boost as the gain from reducing friction. Now go buy a good turbo roller cam and your in business. And get a multi keyway cam sprocket.
I've never been able to figure out, is the roller camshaft itself a hotter cam (what are the specs compared to the slider cam?) or are the power gains from lessening the resistance of the valvetrain?
There are no power gains...it's just a "stock replacement" roller cam that is more reliable than the slider. If there is a gain to be had, it's because the old slider was worn out. The roller actually has a bit less aggressive specs than the stock turbo cam.
