You took .020 of the deck, what did that leave you for CC's per each head?   What was the cold cranking of the 120st motor with the 600 cam?

CCP was  in the 197 range  here @ 700 feet and chambers 92.5 if I recall that was many builds ago already .

Thanks Steve one other question was the piston the stock piston or one of yours  5 cc ?

Where would you guys be looking for the compression?  these kits are advertised at 9.9:1 correct? 

I'm assuming the answer is milling the head?

Compression will be 9.8 with a 96cc nominal head and the supplied head gaskets. Using a .030hg and a light head mill could get the compression into the low tens very easily. I am assuming they left the stock barrel height which leaves a - deck height of about .004-.006 typically.

'Wish this Kit was available when we were building the '09...

Bumping the compression to 10.2+ or so and the T-Man 625s would give the 255 crowd all the low end that they love and still carry out the back door

JMHO, your results may vary...

the 117 kit is a great however I feel its going to open the door to more building than just bolt on .. Due to the great guides these have in them ,    then the 117 is going to need the larger t/b and at that point if you can build it with a cam that will produce great tq why not opt for one that can do both.. 117 AIR pump will allow the use of larger cams with no real issue to the low end power.

The 259 cam will not work well than ,you suggest a bigger cam?

I think that's only if you don't have the SE Heavy Breather Elite Performance AC, which came with my CVO, so I think I'm okay with what I have.

My order was placed today! 

Went with the entire kit, swapped the 585 cams in vice the 259

I've got a kit coming too. Are you saying you're putting 585 cams in your kit rather than 259e cams? If so, what did the dealer tell you the difference would be in performance. Or do you already know. Interested. Might do it too

I ordered the 'race kit' and swapped the cams.

From what I can tell it should be a low-mid range torque machine and carry the torque pretty well. From the way the data looks, the 259 may make a few more peak HP but I believe it takes more rpm to get in the torque band.

The kit is good value since it comes with lifters pushrods and cam bearings as well as the 58 tb and injectors.

Plus the head badges. That's worth the price of admission.

X2 .... going to wait for a while

I am fascinated with the premise of bumping displacement with a bolt-on kit while doing a head swap.  I am only considering the piston and cylinder kit, as I already have the cams and intake covered.

However, my engine builder with 35+ years of experience thinks this kit is terrible idea!  The reason he cited for his disapproval was “the spigots are longer so the pistons don’t fall out the bottom and a larger dia. Those slipper skirt pistons with the no tension oil rings are questionable also, I don’t use them.”  I understand what slipper skirt pistons are, but I do not really understand what “no tension oil rings” are.

Personally, I wondered more about the steel liners inside cast iron jugs and all the related issues therein.  I definitely am not interested in doing anything that compromised reliability or longevity of 4,500 mile engine.

Can anyone with first-hand technical experience with this kit confirm or deny anything my engine builder is saying who has not laid hands on this kit yet?  I know people have strong opinions here about Screamin Eagle cylinders and possibly Screamin Eagle pistons, but is my engine builder correct?  Are the pistons in this kit inferior (slipper skirt with no tension oil rings) to stock 110 CI pistons.  Are the spigots longer or larger diameter?  Any other concerns with steel liners and everything getting real thin?  Ie cooling, gasket sealing, etc

Thanks In Advance,

They don't sell the kit with a head upgrade.

Let the product mature and your builder may need to build a new database.
Mahle is a very high quality piston and nothing they produce is just thrown out there. I am sure the piston and cylinder were developed as a pair and the proper sealing and longevity issues were taken into consideration. This is becoming a production displacement.
