Here in Israel we have 95 or 98 octane.
I hate you. You are officially on the "You Suck" list. :wav:

watch out ! the octane ratings will be different. There is ROZ and MOZ. Israel 98 will be US 94 Even with US 94 (german 98) I do have pinging problems today. Not knowing how good the fuel supply and quality in Israel is in reality I would be careful when choosing the pistons and compression. Carsten Carsten
Thank you, Carsten.
In Israel I use the 95 octane. Supposing that I will rebuild the engine, what should I do choosing the Pistons? I know that the original specs for the engine compression is 8.2.
You should be fine. I run my 8.8:1 compression motor on 91 Octane (our highest) without detonation.
.............:edgy:..............I'd really doubt the block suffered any damage, crank and a rod, maybe...
The question is why did it suffer a rod knock? Oil system failure? What were you doing when the knock first occurred? We know the two previous owners, did anybody allege that the engine had been rebuilt?
A buddy of mine has this. I would have no worries about buying something he built. He probably wouldn't want to be bothered with shipping it though but I would lend a hand as long as I was reimbursed for my time.

8.2:1 would be a ideal number. If you cc the heads and measure the amount pistons are down in the bore, you will most likely find it to be more in the high 7s. Your engine should have a cast crank, if you did wipe it out, doubtful Ohio crankshaft was selling cast cranks for $290 connecting rods can be had through many of the high performance U.S. engine builders or just order aftermarket rods for cheap insurance. If you go with forged crank you will have to change you dampener and remove the weights on the converter, even more work. Rebuild what you have, if the rod did not break and or turn blue, it can be refurbished common practice no matter what kind of engine.
8.2 compression means it doesn't have too much power. But it will run on US 91 (german/Israel 95).
IF (big IF) there needs to be machine work done on block or heads to get them done correct again it might increase the compression.
When we rebuilt an engine overhere we usually go for 10,0:1 but it takes serious measuring building it while living can be easy if you choose 8.2.
It is up to you and how you want to use your Imperial.
8.2 would be stock and make it a cruiser as it was in the past.
But like mentioned earlier:
Disassemble the engine and go from there
