Who has a cam like this?
« on: October 30, 2017, 05:11:53 PM »

Hi guys,
With so many manufactures out there coming out with new stuff it's hard to keep up with what's new.
Looking for something that is gear drive. I've been on the big boys site but there grinds are not up to date.
Lift, 630-660
Duration, 256-260 would like close to single pattern cam as possible. If it different by a few degree it ok.
Overlap, 47-52
Lobe separation, 103-105

Im actually leaning toward more of a 660 at the valve, how it gets there by cam or rockershaft is not important. I would prefer it get there by rocker ratio. The heads will be machined to clear the TDC lifts.

Ok so your query sucked me in and i just couldn't leave the link alone after posting without looking.

Here are some cams to check out.

Andrews TW60g - Really close to your requirements
RedShift - 647 cam pretty close to your specs and a tested performer by many.
Black Widow - BW58   only off 1 degree in 2 spots.
TMan 650 although i dont think he makes it any more is another one.


Some others to look at.
Kuryakin 46g, 546,
woods 9fg
Mackie 598 and 630


None are perfect to your spec, but some get close.   TMan 590 is close except for lift.

I felt the ideal cam for my 120r at the time would have been the combination of the Kuryakin 46g intake and the S&S 625g exhaust lobes.   

Good Luck on your hunt.

The 9f looks to be the closest, but I'm a little worried about the noise..not such the actual noise, but the fact that something is happening differently to make the noise over other cams.
Does that make sense?
Bob knows his stuff though.
Anyone have some high milage on theirs with no issues?
