Going back through a 143 . We have opted to replace the 635 cam with a 640 on stilts .. Meaning that we will use the 1.725 rockers .  Also Went with S&S billet cam plate 3 stage pump . The 3 stage pump is better than the cartridge design  in my opinion ....and, on another note was told that  S&S is now shipping all new engines with their  3 stage and billet plate  :up:


Goal is 215 CCP .. Pistons just arrived and will start the process . 12 cc dome on the new 4.445 piston  .  Ring pack is 1.5/1.5/3.0 Much happier with that over the Wiseco piston that came in it . These are not a off the shelf item ,  pin wall, larger pin boss for increased support, under head milling  .. big thanks to Terry for helping out with this .

Some  minor head work as well . Will be testing a one off SPF ex for this and D&D mega cat .

Beautiful looking piston. I would love to have that motor, I have no business owning one of those however.
Looking forward to the results

It's going in a Road Glide. Are you sure you want to get that close.  :wink:  :hyst:  :hyst:

Well, even RoadGlides need some love once in a while!
Thank God there are people out there for that...

I'd be curious as to what that piston assembly weighs with the pin and rings?

This should be interesting.

Thanks for posting it up Steve.

HD/Wrench

491 grams bare piston  I have not weighed the ring pack or pin + clips  Yet   . Being this is a  race style pin It is not going to weigh what others do. and its not in my library YET .  So I cannot offer the total yet I will though . Give me time ..  :up:

Thanks for posting those. 0.20 over piston, how far do you think these cylinders can be bored.  I got a set from S&S, unfinished.

Very nice!

Somebody is going to have a fun summer.  :chop:

The bore size is a bit oddball so that limits ring availability off the shelf.

HD/Wrench

Don is correct the reason for + 20 is ring availability.  SO its not so much how far but what can you get,..once  you do bore it.. I would not opt for over bore on un- finished I would start STD and allow one more bore& hone .

Case that has been drilled for OEM oiling  :up: :up:

New vs old on pin thickness and length .. As you can see the old pin was not overly happy .

With a thicker wall pin and longer we can reduce piston distortion .. then add in the material in use and thicker pin boss all add in for a stronger part .

Last I heard is that August was when the Harley patent ran out and they would be running the t3 stuff and having the passages drilled for the stock gasket.

It will run for sure. 200 is possible.

Is there enough manifold on these motors to get to 200?  asking for friend.

Well I have seen one that did it .. Not sure but I am willing to give it a try  :wink:
