I didn't title this "Which cam" because most people are probably sick and tired of that question. I know I'm tired of reading about cams. Having said that, I to am undecided about which cam to use. I had the Andrews 26 in my old 2002 RKC with a 95" BB and I loved it. I have the SE 255 cam in my current SE Fat Bob and while I know it is totally different from my 08 SG (which is what I am doing) I still like this cam and it gets great reviews. I talked to the tech at Andrews to other day and he is sold, or at least trying to sell me, on the new 54h cam. I think I would be happy with any of these but I'm pulling my hair out. If this were another 95" I wouldn't hesitate to do the 26's again. But this is a 103. Is the 26 too small? Is the 54h too radical in that it comes on slightly later than I might like. Is the SE255 right in the middle? My riding style is two up most all of the time. Not a hot rodder. And I check every tank of gas for mileage . I do lots of trips and range is important to me. Even with a 6 gallon tank I want good milage and am willing to sacrifice some performance for it. I'm also thinking the 26 would not benefit from heads were the other two might. Meaning the 26 would cost less as I would not be tempted to do heads. Opinions?

I put in the 255 cam with SE heads when I had my 103 kit installed. Makes most of its torque before 4,000 rpm. I am satisfied.

 

Ditto on the 255. My previous bike was a Heritage with a 260 cam and SE ported heads. The Stage II build with 255 doesn't give up much to that build. Plenty of low end torque and excellent passing power on the highway. For the money spent, I'm very happy.

 

I have ruled out the 26 as being too small for a 103 engine. I'm now down to the 255 which is were i'm leaning or the 54H. Thanks for the reply wingman. btw, do you ever check your mileage?

I'm going to do a 103" next winter and Big Boyz recommended the 54H to me. I also found a dyno chart somewhere that showed the torque curve on a '07 Night Train with that setup. Right at 100 ft-lb at 2700 rpm, and gets to about 105 ft-lb and stays there from 3000 - 5000 rpm.

Found the post... Click.

 

255s have been very good with 103, plenty of power where I ride. Cause of early torque bike has smoked a coupl of big boys(103 hi to 124s) off the light considerabley. Not a racer but it holds it own, where it really matters

 

HQ 575 with big boyz heads is where I am heading!

 

258's and the Bike Runs like a Raped Ape
