I'm interested but it depends if it could be modified to fit my 09 Dyna.  I will probably stick to my current plan.  I punched the numbers into the Big Boyz calculator and I get 142.25 cubic inches with that bore and stroke.  -Tutt

SA cases and specific crank or T2 cases Steve?  -Tutt 

[1FSTRK]

Any dyno graphs yet?
Just wondering what rpm for peak TQ and HP.

[No Cents]

I know where one of the three finished S&S 144" engines is going   
right down the street from my house. 
It also takes a different front motor mount Steve...that S&S says is needed so it will bolt into the frame.
I was asked last week if I wanted one of the three engines they had ready to ship...but I passed.

now it's groundhog144...I see   
exciting times for you my brother!

So is this the new 124". .everyone moves to 144"?

[HD/Wrench]

Lee at Backyard cycle got one of them. The engine was assigned to us as we had it sold to a customer in Dallas ,... however customer changed his mind yesterday and is opting for a more mild 124 instead 

So it was passed on to Lee.

A granite one is heading up to Canada. So there will be a few dyno sheets out in the future.

CI inch wise  its 142.75 so maybe that program rounded. Not that it matters any .

Case is not a SA set up.

And yes there are two motor mounts post and pre 09.

Can we order an unassembled version?

[HD/Wrench]

Not at this time.

Moco cases don't seem worth it, I bet these are S&S cases.

moco case wont support that bore

[build it]

I realize that, and they may not be SA cases, but Id wager the cases are more than adequate.

[HD/Wrench]

New S&S T2 case NON SA style

[build it]

Thanks for clarifying, there was a rumor that this engine was based on MOCO cases.

[groundhog143]

 Correction Steve its Backyard Cycle in Harrison Ohio

[CowboyTutt]

Steve, thanks for answering all our questions!     Its interesting how versatile the new T2 cases are.  It sounds like an interesting motor although I think there is more performance in it.  -Tutt

Prepare to find all the weak(er) links in the chain between that mill and the ground. 

[No Cents]

Prepare to find all the weak(er) links in the chain between that mill and the ground. 

that is going to be one bad mammy jammy of a crate motor.
It will put the rest of the bikes components to the test.
I'm sure it will find the weak links quickly.

That's going to be about 670 lift on those stilts, isn't it?  They must feel very confident in their valve train for long term use.  -Tutt
