Wondering what the best s&s cam would be for my possible 106 big bore upgrade. Heads would be 79cc s&s heads. Thanks.

 

Im curious about this too. I was told S&S 551 easy starts would work well. I was also thinking Woods 555

 

I just did a SE 103" upgrade on my Dyna and went with the S&S 583 easy start gear drive cams, I love the fact that I don't need compression releases and she starts right up, sounds a little funny when I shut it off some times but I'm very happy with them. went with the 583 for the lower RPM power curve I have not dynoed it yet, not racing anyone and don't realy care

 

You will be @ 11.0 cr, with a .030" head gasket.
The S&S cam that fits that compression is a .625.
It run at a projected, corrected ratio of 9.3.
The Wood 555 or the other S&S cam you mentioned will carry waaaaaaaaay too much ccp.

.625`s would be the ticket for a real nice hotrod build,but if your looking for a low end,torquey build,you might want to think about just having your stocks heads done (milder touring headwork,85cc would open up alot more "touring" cams like the S&S 551,or .583 & woods 555

 

Im looking to do the 106 with stock heads and cam. I like the idea of the easy starts but im not opposed to others. Done so much reading Ive got crosseyed.

 

We most often utilize the 570 for baggers and 585 for non-baggers easy starts coupled w/ our Silver Bullet Heads.

 

Last fall we built a 107"er/S&S .570/our Stage II Heads/bored t/body/Rhinehart duals, for a client from Syracuse, N.Y.
He let 3 of his bud's ride the bike.
We have 4 jobs coming in from that.

i started out with the 551ez was not real happy with them,dont get me wrong nice pulling cam really didnt have to change but im never happy haha,got some different heads and put 585 ez in and wow different bike better numbers and seat of pants really cant go wrong with either 1,+ the ez start is great on starter,little funky when shutting down but you get used to the ciicking sound good luck..

So after much thought and discussion, going with the s&s 89cc heads with 570 ez start cams. Any thoughts or comments. Should pull hard up to 4800 - 4900 rpm.I think
