A friend of mine suggested instead of doing the 117 kit, that I just do cams instead and save the money. Has anyone just did cams? Which ones and were the results good?

 

Depends what you want out of it. I did cams only, only to go 124 later. Way more money. I've got a good factory authorized Indy who is a straight shooter about 30 minutes from you that did my 124. Just picked it up Saturday. In house dyno tuning too

 

The problem is with cams only in the 110 is the compression is so low, only 9:1 CR

There are cams that will work with the stock Compression ratio, but it's one of those things where you will probably want to upgrade again in the near future.

Either way, to get the best bang for your buck the heads are going to have to come off IMO.

The SE 117 is pretty good value for money and comes with all required parts. You could do it slightly cheaper if you individually chose every component if one supplier had it all.

Best talk to a local motor builder and get their opinion.

 

I had SE 585 cams installed on day one. Dyno'd at 102/116. They sound great.

As stated, I need some heads and compression to pull any more out of it.

 

where's your thread? did you post your gainz in the dyno room?

 

Stock the LRS comes in at 9.2:1 on compression, not bad. It seems a shame to buy an S only to do a big bore. Why not just get the LR instead? Big bore doesn't get you much unless you increase compression and then you have to replace the cam to get proper air flow. If you are only doing one, get a better cam. Andrews 57 should work well for you and will work well from 9.0 to 10.0 compression so you have room to improve if you get headwork or a big bore done in the future.

 

Stupid question, why did Harley keep compression ratio at 9.2 on the 110, and my answer is gonna probably to keep engine heat down. But couldn't they at least do 9.6 or 9.7ish . Wouldn't alittle milling and a cam make a 110 a good set up?

 

That Andrews 57 probably isn't going to work very well.. Corrected compression will only be 8.6:1 or so, and cold cranking compression would only be around 175, maybe a bit less. And this assumes a nominal 9.2:1 compression, reality would probably be more like 9.0:1 or so. Advancing the cams 4° would probably help, but this in my opinion is a stopgap measure on the way to increasing compression the right way......

Like you said though, if [headwork] and a compression bump is in the (near) future, there are certainly worse ways to go.

 

The Andrews 48 if not doing further work then?

 

a lot to do with heat/255 cam.


You are correct, skim heads and thin gasket should have this thing at 10:1 with the correct calculations. Heads still have to come off, so why not do the pistons whilst they are sitting there instead of milling heads which is irreversible. You could say milling heads is cheaper I suppose but 110 10:1 pistons are like $300 I think.
