the piston skirts are the V'd and the botten of the side skirt hangs off the bottem of the bore about 3/4 of a inch mabe a little more I am trying to upload these dam pictures on my computer
I think (sometimes) what Moper meant was when the piston is at top dead center how far down in the bore (below deck) is the piston sitting, eg. .125" or 1/8". This will give an idea what the approx. comp. ratio is for that engine. Also are there any valve relief notches in the tops of the pistons if so how many 2 or 4 notches.
