non hemi deck height

I don't think the question was answered... Block overall height is approx .020 to .025 difference with the NoN Hemi having the taller of the 2 on deck...

If you want to push the flat top piston to the top of cylinder on a Hemi you use a +.020 rod
If you want to push the std oem dish piston to the top of cylinder on a Non Hemi you use a +.020 rod
If you want to swap to a flat top piston in your Non Hemi then you need to add a +.040 rod to get the piston to top of cylinder..
 
In the simplest form . If you add a .250 crank the original rod and piston will stick out the cylinder .250 further.
The cure for that is use a shorter rod , that's not a good option as its too short already.
option two is mill .250 off the piston , that's a lot and likely won't be any piston crown left .
Next is a different piston with the wrist pin moved up toward the piston top. usually in combination with a billet rod and possibly milling some off the piston as well .
Also you can weld a block extension on along with a new sleeve and all the above mods.

The use of less stroke will give some different options .
You might be able to mill .080 off a dished piston.
Take an old one saw it in half with a hacksaw to see how thick the crown is .
The kit method while easier still requires some checking of different things.
 
speed cost money how Fast you wanna Go .
There surly is someone who would.
I'm not interested in investing 2 k into a hopped up predator.
 
That would do it . Any peice of aluminum would work your going to have to mill it flat any way . A place for the pushrods and head bolts , add sleeve .
Definatly need some for thought .
The blocks are pretty weak , be prepared for possible fracture.
