Harley Twin Cam 124ci (2030cc) engine block rebuilt by Hammer Performance with warranty.
(Still has one and a half years of warranty or until 15,000 miles.)
Built to be as reliable and as durable as a stock Harley-Davidson engine block. Can be maintained by any Harley-Davidson dealer and specialised mechanic. 

One of the 3 124-Twin Cam blocks I had made at Hammer Performance in the US (one in daily moto, 1 for drag races, this one was the spare block). I had to stop driving, which is why it is now up for auction.

4 1/8 bore x 4 5/8 stroke.
Heads are ‘smash’ ported and fitted with compression releases. The bottom block was a brand new HD Screaming Eagle 120R crank case that was further modified. Pistons and Cylinders from Axtell.

Built by Hammer based on my specs, build sheet will be included.
Was delivered as Long Block without fuel system, can be used with carburetor or with EFI. EFI from Harley can be transferred. Block has never been used except for a dyno run to test a set-up. Dyno sheet among the pictures. It run 6 times. Always stored in a heated, dry room according to the correct procedures. 139hp and 139ft-lbs (=188Nm torque).
A stock Twin Cam 103 block has 70hp. This one has twice as much.

A set of camshafts will be included that suits your needs as a driver. Together with Hammer Performance, I developed 6 configurations to make sure that this engine can suit any type of driver.
For example: For a Touring with a lot of weight the focus should be on torque in low rpm-ranges, while the focus for a sporty Dyna should be on HPs in higher rpm-ranges. The camshafts will be delivered separately from the engine block and they can be installed within 2 hours by a qualified mechanic.

The block has been lubricated but has not been filled with oil (oil required: HD Screamin Eagle Syn3 20W50).

MSO (origin certificate) can be drawn up in order to have this engine block listed on your vehicle documents in case of a possible engine swap.

I’m not expecting to earn back the costs I’ve made, I’m just hoping that the engine goes to someone who respects it for what it is.

Location: Puurs, Belgium.
