I have another big bore stroker sitting on my workbench.

And I'm too old to go building any more,

But for anyone who's never owned something like this it's a great opportunity. They don't come along very often.

What are the bore & stroke of your racing engine and the bench engine?

No. No numbers, no title

Thanks for that. The question was actually for our friend Fe-head in OZ

Back to the numbers and title. The cases have been reinforced with material all over. Belly numbers may be still underneath it, but I doubt they’d still be legible. He kept an open spot in the vin pad area, but it looks like there’s material over the original material. The timing plug hole has been sealed up.
I’m like you guys, I’d always rather have a title, but this one is a different animal. I suppose you could put it into a later frame with a title and claim it as a replacement engine but I can’t envision this for use on public roadways.
I can text pictures and videos- 714-345-5627. ( never been successful at getting pix to load on this site).

The engine in my sidecar is a small stroker. Stcok bore, 4 5/8 stroke. 65 cubes or 1076 cc's.

The one on the workbench was built (many many) years ago with KH flywheels and Dytch cylinders. It;s about 73.4 inches or 1220 cc's.

I can go bigger in the sidecar if I ever need to but at the moment I have more power than anyone else. Not necessary.

The bench engine is going in to a 62 CH frame for use on the street. My plan is to run it on Methanol as well. That way, I can use up any fuel left over after a race meeting.

Surprisingly, these engines are quite "docile" in terms of running. The sidecar sits on the dummy grid idling just like any other Ironhead. For some reason that surprise everybody. You CAN hear the crack of the high compression I'm running - it does sound like a hot rod. But the 2 into 1 does help dampen them a bit.

But I see no reason why I couldn't run the Dytch stroker on the street.

I guarantee it will shock and stun onlookers, Shock and stun.

I have a few guys around here with Evo big twins running loud pipes. They talk the talk.
I'd like to show them what a "Girls Bike" can do.

Ferrous_Head, A few years back at Bonneville, Dan Kinsey, the rider from S&S who set all their records, told me he runs his big inch street bike on alcohol.
