Jim,
Mechanical fuse is nice concept, but (from experience) I can tell you that the 'fuse' is not all that breaks/bends when one of these lets go.
I got as far as discovering dizzy didn't turn (due to stripped camshaft gear) and at least 4 bent valves on my reco'd heads - called an 'interference' motor. Left me stranded at Bungendore, 60km from home.
...(and later during strip down) maybe the cause of the failure was the loss of a tooth on the crankshaft gear and things all got cross footed and munched......
Regardless, 'spare' motor got me mobile again reasonably quickly.
Solution.....
1. look after it and don't over rev.
2. fit an after market metal cam gear, preferably with new matching crankshaft gear to avoid wear problems.
3. when rebuilding, fit a new one as part of the expense (like timing belts)
Having said all that, I've only ever had one go on me. The crapi was pretty reliable if you paid attention to what was going on under your butt. (aka preventative maintenance).
Remember, these cars come from a different era, when 3000mile (5000km) services were the norm. (with full rebuild after 100,000miles)
