What is the acceptable clearance when building any engine out of the hole? I am not talking dome but the top outer edges. With .002 out and .021 steel shims seems plenty. Is there a buffer for rod and piston stretch when one is hot and running?

I don't know where you got .002 out, but your scenario only yields .019 quench, which is instant disaster. Use standard .042 gasket here.

Sorry, I'm still processing "350 Chevy truck" and "glory" in the same sentence.  What???  The words "turd" and "load" come to mind.  Doesn't seem like much of a competition.  ???

Gee, LOTS more people over the years have built up 360's than 350's. {guffaws} Have you noticed that there are old 350 trucks running in Stock Eliminator? Even a couple Dodges. Know how many old FE trucks there? Zee Row. You're right; not much of a competition.

Guess I just don't pay any attention to the brand X stuff...

I give this post a thumbs down. What little I have worked with a lathe and mill concerning aircraft engines I know refusing to answer a straight forward question like this is pretty childish. Especially when there are a couple of you who have gone beyond assembling parts and pieces and who have blueprinted and built an engine. When I have the experience to help someone I just do it. I don't care what my contemporaries or superiors opinion are. I have spoken to an engine builder and will be responding privately to original poster, no need to answer or comment.

Mathematically possible.  Old school hot rodding.  We used to mix & match stuff all the time before stroker parts existed.

The 360 pistons probably have no valve notches - Mope pistons are dead flat in many cases.  I looked at them as a possible low/low budget stroker deal at one point.  Aluminum don't care what is written on the valve covers - its just dimensional.  The 4" bore stuff works for a 352 - might look at 340 parts  (start at 4.040) for 360 based deals.  Problem is that by the time you pay somebody to modify them you'll have custom piston money tied up...but if you own or have access to a shop its a different game.

Means that to reach the target range of "zero deck" you can mill the top of the piston as needed - pretty easy lathe or even mill project.  Replacement cast pistons are plenty thick enough to handle a .020, .030, or .040 whacking.  You can buzz the FE rods and the pistons to use .990 Chev pins - or just haze the rods to use the Mope pins.

I guess if I was doing this stuff now on a real budget I would have Adney fuzz the crank down to 2.200, get a set of cheapskate chinaman , 6.7, 6.8, 6.585 or whatever rods needed to make things work....

Well thanks for all the responses I have been tied up with other stuff so I am sorry I haven't been responding , here is my plan I will ask speed pro if they can give me a dish volume if not I will buy one piston to check if it is close lucky for me the machine shop I use has a very good owner and he will work with me to cut them to zero chances are it will cost more than finding a 390 crank and rods but at least these parts won't end up in a dam toyota, I think with the parts I have performer intake tq20 cam  and a 600 holley overall I should come out ok. I will also get some satisfaction from having a 360 that runs good.

OK good deal. I think I'm up for a set, too.
