QUOTE(Jake Raby @ Jan 20 2021, 01:00 PM)  I thought you were trying to get a value for a compression test. Based on the data you have in your last post, you'll need to disassemble the short block, and flatten/ lower the case decks accordingly. At the risk of showing my ignorance isn't there an easier way? if I got some flat top pistons without the valve cut outs it would up the CP 8.5:1 Also if my engine is stock how come the CP is so low, is 1.2mm deck height excessive? Thanks in advance |
