Default Wanna build a cheap big bore stroker ?

Anyone thinking of building a cheap "Saturday Night Special" probably should have a look at these listings.

I have bought parts from "Leanne" but I never vouch for anyone. Buyer beware.

Having said that - I suspect the listing is accurate.

Branch Ported heads (as long as they were done right - what's in nemae ?)

Cylinders and pistons

S&S rotating assembly

https://www.ebay.com/itm/Harley-Davi...53.m1438.l2649


This is literally a big bore stroker kit in a box.

If I had any money they would be mine. I'm tapped out right now.

But with a worn out doner engine, a little work, a little time and a little money you could shock and stun your ex-girlfriend, Neighbors, parents and probably yourself.

No, really it's not me. If I had the money I'd never let anyone else know these bits were u for sale.

It's getting harder an harder to get the bits together for a big bore stroker anymore. And almos no one pulls one apart and sells it piecemeal like this.

At the moment the bids is $1360 for all of them together. If you were really going cheap you could probably put together a complete engine with it for under 3 grand.

I see people trying to get $1200-1500 for clapped out 900's.

Hell, I bought a complete 79 for $1200 a couple months back. And the engine in that is GOOD.

Biggest problem is some parts are no longer available new.

S&S rotating assemblies the last time I bought one was to "special order".
I see 1000 kits including the pistons for stock bore at about 2 grand.

Minus minus cams probably in the $500 bracket.

Port work on cylinder heads by Jerry Branch no longer possible. Others might do them but your probably looking at $2500 for a set - you supply the heads.

Cylinders aren't available except "special order" again, Ron Trock won;t do them you could talk to Flathead Power but I know I couldn't afford them.

If you want to do a new big bore stroker your much better off using the 1000 cc engine to start with. Ron will do cylinders for them for about $900. Pistons will run you another #$400.
But you still need someone to port them. Stock heads won't flow enough to feed a big bore stroker.
And almost no one wants to port cast iron heads anymore.

It makes sense for me to build 900 based engines as they fall into what we here call Period 3 Unlimited for Historic Racing purposes.
My engines need to be based on pre 1962 cases. So 1000 cc cases are out.

But almost no one in the USA (As far as I know) has a road racing class that suits these engines.

Cycle World built an engine based on these components and it's first pass on the 1/4 mile (before dialing in the carburation) was under 12.5 seconds. They were confident that 11 second runs would be possible after tuning.

Just sayin' this would make an amazing street bike for someone.

At the last auction, this shaft sold for 428$. I don't know why he sells again.

Easily!
Terrific bargain, can't be done for 2 X the price.

S&S breather instructions for IH stroker:
1. use 1972-76 rotor
2. only port pump tower to .419" wide
3. duration 227° total

I'm watching Ebay on these items. FYI crank assembly is 4 and 5/8s, cylinders are 200 taller, lower end is not big enough for those cylinders. PS let the bidding begin!
