Engine decking issue(help)

yellow rose said

First off, yes machinists make mistakes. I've made plenty. But it damn sure wasn't missing a deck height by that much.

If you cut the deck to low corner, you never make the mistake where one side is shorter than the other. That's why you measure first. But, if the mistake was made, and cutting the second side ended up short, you machine the first side so they are the SAME and make up the difference in head gasket thickness if need be.

And, we have a member who thinks guys with a stock block, probably making less than 500 HP should bore the cam line, then finish the mains and then deck the block and do all that for 200 bucks. Yep. That's what everyone needs.

It's not that hard. You don't need a CNC machine to get the decks straight and square. That's why God made dial indicators.

Guys like you always have an answer but no knowledge at all. Our machines are all manual No CNC's here.If you were a real machinest you would have saw that on the pictures. If you read that process I mentioned it was for new blocks. I mentioned that so some would understand the process in which a block is created. square off the crank/cam center line.

Ah but You know for sure that your stock block was perfect from new. You my friend do not have a clue on why square decking is an important process. I would say about 40% are out of square with different deck heights side to side causing the wrong intake surface angle. Why not check if the core of your engine was built accurate? I forgot you do it with a dial veneer and a tape measure along with your naked eye. Micrometers and "Digital Read Outs" (DRO"s) are for beginners. And just because we bought a Bed mill our process is only for the rich that want to get paid for what they do.

It seems like attacking someone for giving good advise is OK in your eyes. Are you the guy that did all the posters machine work and didn't have the equipment to square the deck.

How would you check the deck height without using the crank/cam center line? Without a fixture you can't check it or correct it properly. If you didn't know that you are a wanna be machinist. I myself had to ask my son because I never saw him using the pistons in the bore to check the deck. H just got a Dart SBC race block. You should see the mess a prehistoric machinist made out of that build. Fresh from a engine builder in Virginia.
