I am trying to figure out my compression ratio and I can't find the specs for the cc volume on stock 360 dish pistons. Anyone have this info? It sure would help me, I'ts the last part of the equation I need.

63dartman,
The stock piston dish is 9.8 cc's and the aftermarket is 10.8 cc's in .030.

BJR, Thanks again!! You are a wealth of knowledge. I am coming up with 9.72 using a .043 head gasket and 4.06 bore. My cylinders are at .095 in the hole. Will I be o.k. as far as piston to valve clearance using the .043?

Yep, your definetly far enough below to more than enough clearence with that gasket.

I agree! I came up with 8.2:1 assuming a 65cc camber in the heads, even a 60cc chamber only brings it to 8.5:1

The mopar gods will guide me!! I believe that everything will work out, I just talked to the machinist that did my heads. Noticed that there was a 4 door 63 dart parked across the street needs some attention, guess who drives it.....The machinist that did my heads. Got to talking and he needs a push button assembly for his ride. I told him about fabo and he is going to check us out.
As far as fitment problems, I think the only issue will be the intake. I was told by the shop that they will mill the intake as needed for me with the price of the head milling (267.00 out the door). Really a great bunch of people.I already have all of my valve train components to make it work right.
I think that if I take my time and do it right I will have the performance that I want, I may have taken a non-traditional way to get the job done but, that's part of learning. Next time I build an engine it will start with the right components down in the bottom.
