I have an 08 Road King with a 103. To my knowledge 08's came wiht 96's. Do I have a screamin' eagle?
 

I think Harley started putting the 103 Flhp (police) in 07 until current,any help from you OLD guys.Hahaha

The Screaming Eagle model (SE RoadKing) was a 110 in 08. Are you sure it's a 103? There certainly was a big bore kit available though.

 As Jimmy Acorn said it is a stage II big bore kit. It is essentially the same motor available in stock 103's. CVO's are 110 cu in

  with Jimmy and StBobber.  The 2008 came with a 96ci stock and 110ci on the Sreaming Eagle.

They started putting the 103 in the stock touring bikes in 2011.

Flathead: 1909-1936

The Flathead was named because of the tell-tail flat vented tops that are recognizable at the top of each cylinder head. This is the famous motor that propelled the Harley-Davidson to victory after victory in the motorcycle races of the twenties.

Knucklehead: 1936-1947

On the eve of WW2, Harley-Davidson introduced an overhead-valve V-twin with knuckly looking valve covers. The new motor, affectionately named the "Knucklehead", performed well both for HD and for America in the difficult years to come.

Panhead: 1948-1965

WIth improvements to engine design, like hydraulic valve lifters that supplied oil through rocker arms, the Panhead hit the market in 1948. It was named for the pan-like valve covers replacing the knuckle covers.

Shovelhead: 1966-1983

By 1966 the Panhead underwent still more improvements. The most noticeable being the distinctive enclosed cylinder head in a sleek, slightly curved top. At a glance this looks unmistakably like a shovel with the pushrods tubes resembling the handle of a shovel, and the shovel itself.

Evolution: 1983-1999

In 1984 on the heels of a bold employee buyout of AMF, the motor company went public and introduced its now famous redesign of the V-twin. This radical new design utilized styled square blocks to house the valve train. This motor, revered as the Evolution engine is known amongst Harley enthusiasts as "the Blockhead".

Twin Cam 88: 1999-2006

With numerous American motorcycle manufacturers trying to surface and resurface, Harley-Davidson introduces its most revolutionary engine yet. The Twin Cam 88 gets its name from its two cams versus the single cam in all its ancestors. This motor also goes by the nickname "Fathead" for just exactly that, bigger heads. With this new engine design Harley-Davison puts one more notch in its insurance for success.

Twin Cam 96: 2007 - Present

With an increased demand for a more powerful engine, Harley increased the size of their famous twin cam engine from 88 ci to 96 ci.

Twin Cam 103: 2011 - Present

Harley increases the power again this time to 103 ci.  As of 2011 the 103 motor will be stock in all Harley Davidson Touring model motorcycles. The new 103 ci engine also includes an integrated Oil-Cooler.

I don't know how to attach reference's from another web-site but www.totalmotorcycle .com This is what I found there
2008 Police   RK FLHP =103ci.
2008 Fire/Rescue RK FLHP =103ci.
2008 Peace Officer RK FLHR =96ci.
My wife tells me I'm always wrong so I could be again I guess! I also found similar results on HD forums but now can't find the post so that means it didn't happen.
