A feature of the Forum is that it caters for ordinary Sevens which in their lifetime will never attain valve bounce revs, and extreme racers running to 7,000 rpm, with triple the big end loading. The requirements are poles apart.
Has anyone ever encountered a Seven engine with original Austin big end bolts not visibly stretched by over tightening?? The original bolts have the merit of very close fit, hard to duplicate except by fitting down 8mm.
The incredibly tight dry fasteners on moderns, presumably made of something very tough, do distort sense of feel.
