I grew up watching Dad brass-fill and CC cylinder heads on flathead Ford V8's. He ran bored and stroked "239" engines displacing close to 300 CID, with 11.25:1 compression, on an alcohol/hydrogen peroxide fuel mix, and turned a 4 1/8" stroke crankshaft a little over 6,000 RPM! All on 3 main bearings! When one decided to come apart it looked like a hand grenade went off in the oil pan!
