I have a block which is part of a long term 'when i have time' top end rebuild. It has already been skimmed on the top face (but not the bottom) but by how much I don't know. I am planning on fitting new pistons as a part of the process when pennies allow.
I have gleaned from here suggestions to assemble, turn over with the head 'resting' and then 'feel' the head to see if the pistons are hitting it. Also just putting a flat edge on the block surface to ensure pistons don't protrude. I also appreciate that although a standard engine and so not hitting high revs, there might be some movement in the 2 bearing crank.
So that I know where i am starting from, is there a reliable measurement for a 1930 block height and a generally considered amount that if skimmed doesn't cause a problem? At least then if it is 'obvious' that i will need a shim I can save one assembly process.
thanks

Enjoy yourself, it's later than you think!
