size is only limited by your wallet. It came with an 88 or a103 (can't remember the police bikes engine tgat year) it could be made into or replaced by a 95, 98, 103 107 110 120 124 131 135 or 143.

suggest you do a bit of research and decide what you want to spend and then ask your question again.

Ya need a twin cam motor that came with a five speed. ‘99-‘06. Mostly 88”s but they can be made into lots of different sizes...

Are you looking to build the engine bigger, or replace the engine completely ??

A Screaming Eagle parts book has many ways to get to a bigger engine, big bore
kits to Long Block replacements. How much do you want to spend ?

Welcome To Our Forum, Lots Of Good Info Here.

If you are asking if a 96" or 103" 2007 and newer motor will fit in your bike, the answer is
No.

If you was going to use the 6 speed with it the 96 and 103 will fit. There is a rider on this forum that put a 103HO in his earlier touring bike

I believe they came stock with an 88, but many had an upgrade option to the 103. Someone here should be able to tell you what to look at to confirm.

Thanks everyone, what I'm trying to do is make my motor bigger, I have picked up a 103 basket case and also the top end from a 110 cvo bike and was hoping I could use parts off of both to put on the 96 ci with 6 speed I have in it already, I'm running a reaper 585 cam with vh true duals and s&s oil pump and cam plate with precise fit pushrods. I want to have a bagger that will smoke most other baggers out there. Plus I have a 2005 roadking with the 88ci that I want to make bigger. I've already did some work on that as well by putting s&s oil pump, cam plate and lifters in it. I was hoping to use the top end of the 96 that I have on that but don't know if they will bolt up to eachother since one is the 2005 and the other is a 22007.Will the 07 top end bolt to the lower 2005?

There is a fundamental difference between the 88 and 96 engines, in the way the oiling system links between the oil tank (under the tranny) and the engine. We can't easily mix the two, but you could have your current engine built up into say a 110".
