383 Build

I'll add something... The blueprint deck height of a package is 1/2 the stroke, the rod center to center length, and the compression height of the piston, all added up. Just my opinion here... You are much better off choosing a package, and then fitting the block to it, then measuring the block, and then choosing the package. Reason being, when you have the thing square decked, your shop can set that dimension where ever you want. And you're having it square decked anyway. 383s are notorious for being taller than they were supposed to be. No 383 was ever even close to "10.5:1" because of this fact, and other quality control issues with mopar. I like the KB162 flat top, and I have the deck cut down to get the top flush with the deck. That's just as Rumble said.."zero deck". Domed pistons are not measured from the top of the dome, but rather from the top flat around the perimiter. So a zero deck dome will pop up the height of the dome from the block's deck. In any case, the KB162 needs a deck height of 9.956, and most blocks are in the 9.98 area. Tallest I ran accross was over 10.00. How that one ran without ticking I have no idea.
