360 stroker

Did you have the block machined, or did you buy it from someone? Your decks would be shaved .108 from 9.6 blue print spec…which the machine shop would have charged a lot of money for that many passes. And most factory blocks have quite a few thou over the 9.6. Not being mean but I gotta think you’re measuring the wrong part of the piston. Also, if the decks are that low you’re likely to have horrible misalignment when you drop the intake on. Can you check with the machine shop?
I bought motor but on tear down had 1972 main and rod bearings so I assumed it hadn't been torn down . I am a rookie so I could be wrong but the piston comes out of cylinder and my measure with dial indicator was .090. I am learning the hard way and I know a lot of people have done 408's I just didn't know if this was common . Thanks for comment
