Here is the latest inspection pics. More silicone! This time in the water passage of the block.
Camshaft is not stock. It's pretty big as a matter of fact. It is a Bug Muther Thumper! I looked up the grind from the number on the back of the cam.

With the flat top pistons and the heads that it has 8 really have no idea what the compression ratio currently is. Thinking about changing the cam to something like a XE262? What do you guys think?
Here are some pics.

Well, at least it is Hi-temp silcone in the water jacket LOL. Being a '72, then the factory pistons would be low compression ones... like around 8:1. You can carefully measure how far they are below the deck at TDC; they will probably be something like .070-.080" below deck.

Man, that cam would really dump the low RPM torque into the toilet LOL... less than stock /6 territory for low RPM torque. IMHO, you are on the right track for the new cam.

How do you intend to use this engine/car? And as asked above, what rear axle does it have? Have you figured out what torque converter is in there? Those things are all gonna play into cam selection.
