So my buddy has a '15 SG that he's bumping up to a 110"He said he'd make me a smoking deal on his takeoffs so I could go to 103".What all is involved in doing this?What all parts do I need to get from him?I can do all the work myself,and am considering cams while I'm at it.Can I use my throttle body assy.?Thought about getting a tuner as well.Any advise before I start spending $$$?
Mines an '07 Softail Custom.

 

Don't think you need much at all. Gasket kit and oil. Replace your jugs and pistons with his. May as well throw in a cr575 cam too and get a good tune afterwards.

 

Pistons & cylinders,get new rings

 

This is kinda what I was hoping for....easy swap.So as far as a tuner,could I just theoretically set a tune for a "103 w/ V & H pipes and open intake",or would I have to do anything special?Thinking a PV tuner,and Target Tune.What about the throttle body?Would they be the same or would/should I just use mine?

 

Same throttle body. Use the tune you suggested which should be ok for a base. Not gonna change the cams whilst doing this?

 

One and done. No brainer at this point.. Take advantage of the down time.. You won't regret it....

 

I do want to change cams.......now of course....which cam to run?I have dabbled in the numerous threads on this very topic,and am still undecided.

 

Feeling that ^^^^^^ see above

 

Assuming 85cc chamber, and a .030" head gasket,(10.0 cr) you'd be in good shape with an Andrews 57, S&S .570, or a Wood 6.
You could, however, also include a set of good cylinder heads, and a port-matched intake manifold, to up the power.

As Scott suggested, I'm not too sure about the Andrews or S&S cam but I do know that the W6 carries a real nice curve and carries it out very well to 6k. The attached is in an 80"er that Scott built. I know it's not a 103"er but i'm only posing it so you can see what to expect from the W6 cam...

SORRY, but I'm having a problem Finding the dyno sheet, when I do I will post it....
