cam info needed
I have been seeing a lot of posts about Andrews, v-thunder,Woods, and other cams. The one that I have seen no comments about is the S&S 508 cam. I am comparing to EV-13 and V-thunder 3010. Ideas and/or comments about the S&S 508 would be appreciated.

Interesting, it's not on the widely circulated camshaft lists. I'd never heard of it and have no experience but it's got a very early intake closing and short intake duration, but a much longer exhaust duration and more lift than the similar Andrews low to mid range cams. Sounds like a very cilivized cam and what S&S use in the 80" crate engines?
The lid says, "Bolt-in cam intended for stock engines with less than 10:1 compression ratio. Quiet valvetrain with excellent low/mid range torque for touring and 2 up riding".
Do you have one?
S&S 508
intake open 11°
intake close 25°
exhaust open 50°
exhaust close 5°
intake duration 217°
exhaust duration 235°
valve lift .508"
intake center line 97˚
exhaust center line 112.5˚
Intake TDC .141"
Exhaust TDC .110"
If 30° = 2400 rpm and 35° = 3000 rpm, does 25° equate to coming on cam from 1800 rpm?

No, I do not have one yet. The plan is: '96 Heritage Softail with S&S 508 cam, premium lifters, quickie pushrods, CV Performance Deluxe tuners kit and inlet, and either S&S
HI-4N or DDT 2000 ignition. Bike already has what appears to be a SE airbox and Python III pipes. Thought that should wake her up a bit.

Power same/similar to an Andrews 13.
The all-time best plug/play cam for a heavy 80" Evo was the Crane 300, now no longer.
IF, and only IF, you'd consider a Wood 6, with a set of Wiseco pistons, the gain, is HUGE over just a cam swap.
Smoother power, and actually may see better fuel economy.

We need a dedicated cam forum.
How does the Woods 6 play with 1.7* roller rockers?
I can do the math but there's no beating actual hands on experience.
One of the factors I considered was deliberately choosing what was said to be a quiet cam, knowing I would sacrifice performance, because I have lowers and do long miles rather than bar hopping. I did not need extra noise.
There's always a bit of extra chat about noise when it comes to cams.
Incidentally, I was bugfix a problem I had with bad cam bushing reaming recently, assembled the bottom end without the crankshaft in it (i.e. cam, breather etc) and used a variable electrical motor to turn them around.
It really amazed me how much noise there is just coming off them alone.

Going from a stock 1.625 rocker to a 1.7 rocker in a w6 cam would change the overall lift at the valve from .510 to .534 and will change the ramping characteristics of the cam and will come in sooner. I have heard that it will also change the duration a little which will change the overlap. but not positive on that one. Some have gone to 1.7 rockers on an se 204 with a big improvement on low end torque so as good as the w6 is I can only imagine a great all around cam but on steroids..... Might actually be similar to a V-Thunder 3030. Not sure if head work would be necessary because your lift at TDC will also increase and change valve to valve clearance..

Yes, I read more/quicker lift moved the power down the rpm scale a little but still let it rev up top. Although they are a TC cam, the SE 204 specs are similar. I'm guessing we are in a very safe zone.
Likewise, I read - and so therefore do not know - that STD 80" Evo heads did not actually increase flow after .500" lift, therefore there being no benefit to going above unless you have done head work. A lot of cams, especially bolt ins, seems to stick at .495" I suppose because of this?
There's nothing better for building body that giving a little steriods to an already good performer ...! But I wondered how fast the Wood 6 ramped and it would became an issue to do so even more?
I don't mean to crash a S&S 508 cam thread but there's a lot of talk on the internet about higher lifter rocker arms on these more moderate cams to make them perform better.
Is the longer later exhaust duration is where the EV-13 and this one burn up all their fuel better? Does the 508 have the same cool running effect?

I'm a fan of the V-Thunder cams, while the valve springs need to be set up with some grinds the power band comes in much sooner than most others and pull solidly to redline. Nice having the grunt when you want it and not having to get the RPM's over 2500 to 2800 to get it , mid grinds have great roll on pull. Other selling point is they don't beat hell out of the lifters.
