Stock 96" with 585 cams and s&s 79cc heads. Would this be any good?

Well with a 4 inch stroke and a flat top I'm at 199 cold with a 45 int close and a 76 cc chamber and 0.30 cometic gasket . If it was a 4.3/8 stroke it would be higher.

Why would it be higher?  What is "it"?

I think "IT" is CCP and by Bigboyz calc his ccp should be 220

QuoteIf I keep an eye out for a reasonably priced set of s&s 79cc heads would this be a good combo?  Big boyz calc say that would be 10.15:1.    It would I be better off getting stock take off heads and having them worked?  My budget for headwork would be about $500ish.
Like to get as close to 100/100 as possible

Thanks
Cut .010 off the bottom of the jugs.
Take your stock heads to 76 cc (or those ones for 50.00 .)

Good tune and you got your numbers

total volume has changed of that cylinder max if I go to the stroked set of wheels . Not excatly sure how much higher he would be . I don't know what his deck is at . And he is only at 96 ci

I get 189..Same calculator

What numbers are you using?? 96 ci motor? 79 cc chamber? 45 deg in close?

Alright so never posted before but read here a lot.  Currently have a 2011 dyna with thunderheader and intake tuned.
I don't have the $$ to build the 107 I eventually want but think I could probably swing a low budget 96" to hold me over a couple years while I save.  I'm pretty set on the s&s 585 cam after looking at lots of dyno sheets they would fit my riding style well. Obviously have to do heads to get the compression up.

  A 103 with a well loved on set of factory heads will get you every bit of what you want.

  Scrap the whole idea of doing anything but a bolt in with a factory 96 it just does not work.

  While this build is a 107"er very similar results could be had with the same combination of parts @ 103"

  No BS,NO PMS and will run on fuel you can get anywhere.

  Sachs or WFO Larry can widdle those heads that are on your scooter to smoke any of the s&s heads that would the build you are doing....and you would have heads built to much higher standards than S&S can dream of for probably ALOT less money.

Well you all got me leaning towards doing big bore and cams now, And heads later.  The only reason I was really trying to avoid this is I don't have the space to leave the bike torn down while my stock parts are getting worked on.  I need to have all the parts in ham so I can tear down an install during a weekend. This limits me to the rev performance kit since there the only ones who offer all black / non highlighted cylinders in a 107 kit although I have hear mixed reviews about there stuff.
Plus I'd hate to spend $1000 on a kit when stock stuff can be bored for much cheaper

Talk to Hillside or prodrag, they probably have cylinders to send you, and can charge a core charge maybe? See what they say. For that fact, you can buy take of off cylinders for about $120.00 a set, then resell yours later.

It will work to get him what he wants . 100/100 with stock heads.
Nothing is sent all over the country. A 50.00 set of stock heads , cut .060 of of them put a .030 head gasket on it and rock on.
Or spend the 2000,00 and get 5-10 more hp.

We don't even charge for cores, as we work on an "honor" system here.
We just need the cores back once removed from the bike.
So far, we have NOT had a problem with this method.

Think you can convert it to EFI , and get it tuned for under 2000.00?
Crazy when you think about it, at your level isnt it Gordon?
Maybe a little more of a right sided cam might get you 5 hp ?  :potstir:
