Engine decking issue(help)

Post 4 is how you do it. Did you measure the rods? Did you measure the compression height? Did you measure the stroke on every throw?

If not, the deck height number doesn't mean ****. If you measure all those measurements, and they all end up at blue print dimensions, then it means something. They never do.

Put the crank in, and I only use 1 piston, and drop it in all 4 corners and cut the block to the low corner.

Chances are, if you want zero deck, you're going to take a bunch off. If you need a positive deck, like if you are using open chamber heads and you want it right, you'll be taking a bunch off.

My last block took .080ish off to get the piston up .045 past the deck.

You have to measure the corners, or take all the measurements and make them all to blueprint specs.
