From the tips page above, it says this:
"
All B20 and B19-B21 before 1980 (with 8-bolted flywheel) have trouble with low-strength rods,
they are useless if you use the engine above 6000RPM. If you have this engine, rebuild it to a 6-bolted
crankshaft whit corresponding flywheel.
"
Thats the exact opposite of what I haev read elsewhere. ie, the 8 bolt engines are the better ones if you are going for max HP. Is there any other info on this?
