i talked to s&s todya and they were telling me that the 570 were close to the same as woods 555.... im planning on getting head work done and putting in s&s 570 cams and needed to know if anyone ran this or had any info good or bad? im looking to go from 0-110 faster than the other guys i ride with

 

I put the woods 777 in a 2011 103 ultra and love it. Power to sell and hells of torque. I chose the 777 over the 555 due to the fact it has just a ltl more lift. You can call Bob woods and talk to him personalty about your build and he will give you a lot of good info.

 

The 570 needs more compression to perform up to it's potential; you would need to pull your heads and have them decked for the extra compression.

You will be happier with either the Andrews 26 or 37 or the SE204 for a cam only upgrade.

 

i should have put this in there i plan on having my heads worked at the same time

 

Good move; 76cc-78cc chambers with a .030" head gasket will get you there.

 

Get the "easy starts". .570 a great cam IMO. 10.0:1 would be a good target.

 

What kind of numbers should be expected from this set up with a good tuner and a good pipe?

 

If looking for a "cam only" upgrade, then an Andrews 48 is your man, but if you want to be the lead dog, then you may want to consider this;
Bore to 107"
Wood 8 cams
Heads that roll off north of 165 cfm @ 10" @ .600" lift.
Your riding buds could use gps units for Christmas at that point!!

I also am going with the S&S 570 EZ cams. I am targeting just slightly north of 10:1 static compression which will put me right at 9.3:1 corrected compression.

I also looked seriously at the Woods TW5-6 because of the earlier intake close, however on another forum a member had both on the same build and the dyno charts are not much different.

TW5-6 pulls torque nbrs about 150 RPM sooner and makes slightly less top HP, but they are really close.

Add in the fact that Woods cams are expensive, and the S&S cams include the EZ start so no need for compression releases and I think the S&S 570 is good value for the money.

 

Those cams in a shorter stroke 95" with the early SE Performance heads out of box (76cc chambers), SE flat top pistons and .030" head gasket will hit 100/100 every time.
