Update!

I figured I should have a degree wheel instead of paper substitutes.

Image

Pistons cleaned up.

Image

Intake manifold flange surface wasn't so great (buggered up), so I resurfaced it.

Image

Image

Piston to valve radial clearance is way too close.

Image

After some medium butchering with a carbide rotary tool and some sand paper rolls, there is about 0.070" clearance.

Exhaust:

Intake:

Ready for cams! Almost. Some of the cam cap threads aren't healthy. I'm going to increase the bolt size. I could use threaded inserts, but there's already 2 that I've increased the size on, so I might as well just do the rest the same way.

Using threaded inserts has some advantages:

Caps remain unmodified, less work
Stretch is more, so tension more reliable, more chance of staying tight
Grip in the alloy is relatively larger compared to the head, less chance of more stripping
No possible clearance issues or flange bolt seating issues

In either case, good work and thanks for posting :-)

Cam cap bolts drilled/tapped.

Image

Engine timed. Valve cover painted. The paint can cap was red, but apparently it's going to be orange. Oh well.

I'm going to fill the motor mounts as they are torn and rather useless currently.

Image

Apparently people have used products like these with success. I'm going to give it a shot. I don't know what the shore hardness is, but I expect it to be a little less than 3M Window Weld.

Image

I really didn't like that orange/red valve cover, so I painted it again. First with a metallic base, and then PURPLE!

After some further research, the shore hardness of these is as follows:

3M WIndow Weld (was an option i considered) - 55-60a
Loctite PL Premium Polyurethane Construction Adhesive - 90a
Loctite PL Roof & Flashing Sealant - 28-32a

The roof sealant is like a rubber band in hardness. Construction adhesive it is.

1) My truck cab mounts are filled, used windscreen urethane sealant that I had for free in those days, worked OK but never fully stuck to the rubber, so relies on physical shape to remain in place
2) Plus one on the orange/red, love the purple, nice work, looks really sweet now, the weird shape adds to it instead of just looking bad :-)
No 3, off to bed.

This was hiding under some shiny paint.

I suppose I'll have to add some steel.

Made a little progress on this rust area.

Some more working of the steel required.
