just got back from the machine shop where they pointed out that the roller cam gear would NOT fit my old distrbutor shaft. what is everyone running in their late model engine???
someone told me to go to autozone and get a 1985 manual mustang dizzy for $55+core. it works with the roller cam and the DSII ignigtion already in the car
I was running a bronze gear because that was all that was available when I did the swap, but that wore out pretty fast. They now make the hardened steel gears to use with the roller cam and the original distributor and this is what I am running now. I believe the one I have is this one: http://store.summitracing.com/partdetail.asp?part=MSD-85833&view=1&N=700+150+ A few different companies make them. -Corbin
Here's one with a pertronix set up http://store.summitracing.com/partdetail.asp?autofilter=1&part=PNX%2DD130711&N=700+4294908331+115&autoview=sku says it has a durable heat treated gear.
Can somoone tell my a roller cam is better than a regular cam? sorry a bit off topic but I'm tryign to figure why they are so popular
Faster lift rates(valve opening/closing)Less frictional losses in valve train due to roller components.More stability at higher rpm due to less friction(less valve stability though)Need valve springs that can handle the opening and closing rates.godd for engines you want to rev above 6000 rpm.
I'm very confused on this what you described makes me think of roller tips for rockers, but that's not what you are saying right, What are the roller components? Someone told me my 89 motor is a roller motor, but then someone said that doesn't mean roller rocker tips?? Soprry to be so dull on this but I am just tryign to get a handle on this.
Yes the bottom of the lifter has a wheel on it(roller)instead of being flat like a regular lifter.Same concept as a roller rocker.Roller cams have a different lobe configuration to work with the roller lifter as well.You cant interchange the lifters and cams with non roller cams/lifters.The roller designe allows the cam and valvetrain to accelerate faster than a conventional cam would.Hence the hi perf aspect of it.
