Heeeelp, piston/engine ID
Like I said in my newbie post, this is my first Harley build.
I bought a frame, engine and various parts in order to build a bike(pictured in profile and there it sits)
Anyway the engine which was supposed to be a swap out for a larger displacement seemed fine to my buddy when he bought it. Like he said, it rotated but being the optimist I am I took that with a grain of salt and tore it down as everything is being gone over with a fine toothed comb. When the bikes done I want to ride it not have it become a mechanical hobby.
I pulled the heads and saw a very large gouge down the cylinder wall on the rear jug. Seems the piston circlip had come out and the wristpin had a holiday. Needless to say the cylinder and piston suffered and needed replacing.
I lucked out and found a pair of standard 1340 jugs for $75, bought a set of 10 over pistons for the engine I thought I had, had the cylinders bored and proceeded to reassemble. That's when the problem hit. Wrong piston profile. Before you ask, I rotated by hand.
Yes I did try doubling up on the gaskets etc. No deal. I compounded it by having a buddy locate another set with a different profile and then had the same problem. Call me dumb but willing to learn.
Here's what I'm looking for. Engine ID/year range and correct piston replacement part #.
The engine is FDLS 6049++ Screaming Eagle, The piston, which was 30 over is marked 22768-98. Took the numbers to a local HD dealer and was informed they couldn't help me.
Thanks in advance

Read!
Edited due to misunderstanding.
Getting beyond this I have googled and tried various sites trying to identify both the correct pistons and engine date etc. I haven't been successfull. That's why I'm here. Hoping someone has advice for me to help find what I need.
In the mean time I dug out the piston and took some pics.
Thanks for anything constructive.

Wow, first reply disrespects me.
First off, if you read what you cut and pasted from me in your reply you would see the piston number and the fact that I did state it is 30 over. Second, read again and you will see that I stated it was a Screaming Eagle engine.
Third, I have the pistons I know they have one of the raised profiles and if I took them out of the engine I would know the originals work so I don't need flat or round tops if I want the same profile and compression. What I need is the correct number for the correct profile 10 over.

Got them to upload but they are not appearing. Will work on it.
