Black Widow Cams

Anybody run any of these cams in their bike?

Black Widow Cams - Feel the Poison! - Home

like chucks idea there cardboard - you spend the money and we get the reports -:roflmao:

Guess you want me to git out of the House and git a Job huh.

Tell chuck to go and git a Job somewhere besides his garage and I will go.

Can't work till 12:00 and go in and git back on the couch and go to sleep.

That's my job too.

Found out today, Crane used to grind the cams out of Andrews blanks till Crane went out of business.
S&S bought up crane.

Can't say who does the best job making cams for the single & twin-cam engines, but I can with respect to 4-cam Sportsters & BT's - a combination of H-D & Zippers Performance. I found out about that while choosing components for my 100" Sportster-based engine - all aftermarket Sportster cams whine, except Red Shift's & the reason is the gears on the end aren't cut as precisely. Seems H-D spent like 16 years developing the machine tools / processes & nobody does it better.

So what Zippers does is grind the lobes off a matched set of stock cams, make new lobes on CNC equipment, then press those on & weld, although they'll ship 'em unwelded if you want to play with the timing yourself before you decide on the final position of the lobe on the shaft. But the point is that when you install the new cams, you know the gears mesh perfectly because they were a matched set from the factory to begin with - only the lobe shape has been changed.

Woods sells some gears that will not make the noise
but you are going to have to pay for them

that's another reason on vtwins to
go with the new style chain drive

Spec question

For you guys familiar with the Twin Cam engines - a friend of mine recently bought an '06 Fatboy after the dealership modified it according to what the previous owner wanted. He e-mailed me a list of what they did, but it doesn't include the cam timing specs, other than .635" lift & 60º intake closing. But I do have the part # so maybe y'all can give me the rest of the details:

SE 264 cams; PN 25133-04

Thanx​

This is outta the SE catalog


SE-264 25133-04 Lift .635"/.635"-Duration 264˚/262˚- Intake: 24˚ BTDC/60˚ ABDC
Exhaust: 60˚ BBDC/22˚ ATDC
TDC lift@ valve-0.219"/.211"
This cam is designed around large displacement and high
RPM engines. This cam should be used with high compression,
performance heads, and open intake and exhaust. This
is our highest power cam when used with 110+ and CNC
ported heads

What you want out of a Cam is one that will go from Point A to Point B the fastest.

And all the high lift ain't necessarly gonna do that.

Thanks, Lucifer! Now I know what he's dealing with.

It certainly wouldn't be my cam choice, nor his, for riding around on the roads in this area, but he doesn't have $$$ to spend on a cam change right now, so we'll just get the engine dialed in as good as we can with what he's got & the detailed cam specs tell me what I need to know.

Pretty radical cam there,I don't know much about the big inch engines, but it seems to me to be a top end cam even for a 110", would be way out there in a 96".
Sure is a far cry from the Crane HTC300-2 I'm putting in my 88"cop king
CRANE CAMS
HTC-300-2... Dur-226/236 Lift-.505"/.505" Int O/C- 13 / 33 Exh O/C-42 / 14

Good luck dialing it in, let us know how you make out giving the bike some street manners:devil:

My friend got the bike with this setup, HRK:

* 95" cylinders, 10.5:1 SE pistons (22439-00A);
* SE heads with 2" intakes, "reduced" exhaust (don't know the diameter) & "redesigned" combustion chambers (16933-99B);
* the SE 264 cams I mentioned (25133-04);
* 45mm carb (28040-02), jetted #25, #30, #65;
* single fire coils with 6200 rpm module;
& the bike came with 2 sets of drag pipes - my friend has taken the 2" pipes off, put the 1 3/4" on & put baffles in 'em.

That's what the previous owner wanted & what dealer gave him, although they told him the 257 cams would be better. But it is what it is & until my friend's got some "mad money" to spend, we'll just have to deal with it! He said they dyno'd it & peak power is 4000-5000 rpm, making the most @ 4500, which is pretty much what I'd expect.

Weather's been too cold & wet for him to ride it much @ all, but it's eating spark plugs in no time & from his description of 'em (haven't seen the bike in person yet, photo below), the "reversion" monster was really showing up with the unbaffled 2" drag pipes - no surprise there! But he hasn't had a bike in a very long time, so he's excited & we'll get it going good by the time we get some decent weather.
