Grokk's Project
Got the starter on to do a compression test while the motor is on the stand, and to find out the starter is bad:/. Looking through yellowbook.com found one place in town that rebuilds Starters and Alternators, The guy said he has rebuilt a few before back in the day. $85.00. Plus I had to buy Compression tester adaptor because the kit I bought the threads were to short.

yeah, I went to O'reillys , there's didn't have the bolt whole for the bracket, I figured everyone else probably the same, and didn't want to take the chance it not fitting into the bellhousing. I guess keep it as much stock as I can. If the compression check is ok, next is the Distributor.

You could just drill/tap a bolt hole or swap the case from yours and still be ahead a few $$
I did similar when starters were nonexistent a few years back. I just swapped the nose onto over the counter V8 starters so I could use them on several ohc engines I had built, However I didn't drill the brace holes on those. JM2C

I put a Buick 455 starter motor on a OHC nose cone for mine. Cranks fantastically.

The NOSE is Aluminum.
At the least you can always get one of the new rebuilt offerings to use if needed. It was less then 5 years back when there seemed there were NO cores/rebuilt units avail;

People work magic with TIG welding aluminum these days, even dirty aluminum. Just have to make sure the mounting surface is flat again depending where it cracked.

I went to a compression test, the motor would spin not like suppose to and would struggle on one spot, I took all the plugs out it moved a lot better except at one spot it would struggle, then move freely again. here is pic of the plugs right to left.

With the plugs out I'd try and turn the engine with a breaker bar and see how bad that one spot is. Could be rod bearing or cam lobe, but is likely some disassembly is going to be required.

Good news on the bottom end and bearings. Time to check the cam. You could probably remove the timing belt and see if the engine spins more uniformly (spark plugs removed) to help determine if the binding is the cam/accessory drive or the bottom end. There could be a rusty piston wall now that I think about it.
Both the engines I bought were "running good" but both had really trashed cams. If the bottom end looks good, it could be a cam swap away from a running good. "Burned rubber and ran strong" Also had spark plugs that stuck a 1/2" into the chamber that were black as coal.   "Ran great when pulled a few years ago"   The follower rubbed the keepers and retainer on the left valve.

I'm going to put the oil pan back on, my book says 12 ft lbs for the torque on the bolts but doesn't mention anything about using RTV sealant. Any thoughts?

My luck is all over the map, but I do always use sealant.

I got the Cam tower off, I don't really see anything wrong except for crap in the water jacket. I wonder if it could be a sticky piston ring?
