Yeah, Im going to pick up a compression gauge tomorrow night after work (i should own one anyway with all the other vehicles I work on) and also borrow a dwell meter form a friend. Ill run the compression check and see what happens.

Just a question, having never done this on an older engine, will the continued cranking flood the carb? and is there a way to prevent that?

Leave the choke off and don't hit the gas peddle or throttle linkage. If she floods, she'll just crank over faster. A trick I use to start with a low battery. I've had the cylinders bypass due to failed head gaskets. The bottem end sounded good from what I could tell from the vid. If the compression tests bad, I guess pull the plug beside and see if air is swooshing back and fourth, you can tell. Then its pull the heads time, sorry.

Well I did the compression test, and the results are in

1 = 0psi
2=149psi
3=149psi
4=130psi
5=0psi
6=148psi
7=5psi
8=149psi

Looks like I need to pull the heads

That sucks.

pull the valve cover on that (the left) crank it over and see if the lifters are rocking up and down, maybe flat cam.

or the lifters collapsed or not adjusted the rockers.

or broke studs, may have pulled loose
