What is the deck clearance? Need for cr calculation! Hi,
I try to caclulate the static and the dynamic compression of my new engine combo I want to built up.
I try it with this calculator, but I cannot fill out every field:
http://kb-silvolite.com/calc.php?action=comp
Therefore I have some questions!
I want to use this cam:
http://store.summitracing.com/partdetail.asp?...
This heads:
http://store.summitracing.com/partdetail.asp?...
64cc
And this pistons:
http://store.summitracing.com/partde...0&autoview=sku
5cc
How much is my Deck Clearance? Can I calulate it, or do I have to built up my engine to mesure it?
What is the Intake closing point @ 0.050 lift?
In the cam spec. is only the intake opening at @0.006.
Cylinder Head Volume (cc) 64 Cylinder Head Vol (cubic in.) 03.904
Piston Head Volume (cc) 5 Piston Head Vol (cubic in.) 00.305
Gasket Thickness (in.) 0,039 Swept Volume (cubic in.) 43.731
Gasket Bore (in.) T.D.C. Volume (cubic in.) 04.586
Cylinder Bore Diameter (in.) 4,03 Gasket Volume(cubic in.) 00.000
Deck Clearance (in.) ?????? Deck Volume (cubic in.) ?????
Stroke (in.) 3,48
STATIC COMPRESSION RATIO 10.536
OPTIONAL DATA
Rod Length (in.) 5,7 Adjusted Stroke (in.)
Intake Closing Point (degrees) ??????????
ABDC @ 0.050 lift plus 15 degrees
DYNAMIC EFFECTIVE COMPRESSION RATIO ????
Can somebody help me?
What do you think about this combination?
Do you think that my valves might touch my pistons?
Thanks!

Do you know the history of your block? Stock deck? Decked? Stock deck is 9.025" leaving the piston .025" in the hole. Most are close to 9.025" some variation .001-.002" most of the time. If you have the shortblock assembled you can use a dial indicator to check how far the piston is in the hole.
