I cant recall if you found a reason for the last failure?
If nothing conclusive was found during investigation/repair of the last engine, I would take a really good look at not just the engine but also all of the peripherals, i.e.
- Is the oil system plumbed correctly?
- Is the radiator partially blocked some where?
- Are there support wires inside the radiator hoses to prevent them from collapsing when hot?
- Is there a restriction in the oil system?
- Is the oil pickup the correct distance from the bottom of the pan?
- Is the dipstick marking providing the correct oil level?
- Are the senders for temperature and oil pressure reading correctly (verify with independent gauge)?
- Is the thermostat opening correctly?
- etc etc
Let us know what your engine builder finds/says when the engine is stripped as there may be some learnings for us on this.

Kel,
We thought the problem was timing. I had a couple of badly detonated pistons.
The gauges all read in the normal range today
Water 210 Oil 220
Oil Press 60
We added jet extensions to the rear of the carb in case it was fuel starved. Also installed angled Brasswell floats. Running fat / rich jets breaking it in. nothing appears to be kinked or blocked in cooling or oil lines / hoses.
After a quick check of the motor today (leak down test and running it) the engine builder told me to pull it out and he would get into it.
He agrees that we missed something but we really have no idea. Fuel pressure and flow on the fuel pump appear to be right (checked during rebuild).
I'm going to try and get it out and to the shop Friday.
I'll post up when we get inside.
Thanks,
Rich
