I don’t know what’s so satisfying and scary at the same time about chamfering cylinders on a block after it’s been decked.

People keep telling me to hire someone. “Hire some kid” As much as I would love to train some young soul. Just not enough kids out there wanting to do this work. So I bought machines that can work by themselves. Lol.

Well, here is my first experience with the new Summit Racing Blue Print blocks. This is a small block Chevy for a local shop. First look is pretty decent. There are a few things you need to look out for, like the oil passage hole from the oil filter mount is only 7/16” diameter. I opened up that. Not much material for deck machining. That’s probably my biggest bitch. Cylinders were off location more than I thought they’d be. Thankfully this block was going +.040 and had plenty of room to correct. Have not checked lifter bores yet but that’s next.
