does anyone have any old sealed power books that could give me some info on these pistons???? they are sealed power 2265p...the boxes are marked for export only...cant tell if they are high compression or the terrible 7.9 to 1 pistons
called them---the only info he could come up with is that they were made by TRW back then and were discontinued in 1998---looks like by rough measuring them on the screen, they are the 14cc dish pistons---i bought a set off ebay.. where u gonna get a set of forged pistons for 99.00!!! they have 8 more sets available---they are the good early forgings, not the new foreign made
Not a bad price for 14cc dish forged pistons, but they still are low compression.
I calculate they will give about 8.6:1 compression ratio using undecked block (0.020" clearance), 68cc heads, and Fel Pro head gaskets (.040").
Zero deck the block, mill the heads to 64cc, and use .028" thick head gaskets and you can get 9.3:1 compression ratio.
I did a Google search earlier using "Sealed Power pistons 2265P". It came up 68-70 Olds 350 pistons. It was a page or two back. They would be a great buy, if you can use standard bore pistons. Usually forged pistons need a bit more clearance than cast pistons. Good luck.
