Finally, my first 360 and goals for it! I'll be asking a lot of questions.

I don't know yet. I have never done this before and followed a Haynes manual who suggested top, bottom and the two positions I posted. Specs said: Max cyl bore out of round .005, max taper .010. I will get more measurements and post them up. I don't have a torque plate unfortunately. I am on a budget on this build. I want a fun weekend street car. It will not see the strip. I would like to do as much as I can myself, because that is the only way of learning.


I get what your saying. You have most of the stuff, so learn as much as you can. I appreciate the manual, but it's to just get you by.

Post up the actual size of the piston you are going to use. At this point, if you are going to run it, I would dingle berry hone it and let it go. If it was in my shop, I'd try and get it straighter. Then, I'd be wetting my pants because you're getting very close to too much clearance. It's a give and take thing if you can bore it.

Just for fun, and for learning, why not torque the head on, and torque the main caps and check your bores from the underside? You may not be able to get every measurement but you should get three or four good readings.

It will help you see how far cast iron moves when it is loaded. We won't even add in temperature gradients, casting thickness variations, gasket distortion and load!! It can boggle your mind how much this stuff moves around in dynamic conditions.

Should be fun learning if you have the time. Why not give it a go?

And if you don't mind, post up your numbers. Real world stuff is educational.
