Sealed Power Part Number

[Walter R.]

Machine shop supplied pistons for rebuild. SP Number L2300F. These for 427/425 which should be 11:1. I wanted to check correct compression on these pistons. Could not find part research on internet. Would anyone have correct ID for this part number.

Walter,

Here they are on Summit Racing's web site:

You need the following info to determine the static compression ratio:

piston dome volume, bore diameter, stroke length, deck clearance, combustion chamber volume, cylinder head gasket compressed thickness, and cylinder head gasket bore diameter.

Here's a good thread on the topic:
