If you’ve ever wondered why Swiftune use 6” rods in their race engines then this is a great video explaining how rod length ratio affects engine performance:

Not sure what part of "Pre 66/Appendix K" 6 inch rods come under
I must have some pages missing from homologation papers.
BTW 6.25 is the new 6 inch.

It must be on the same page as multi-web crankshafts and dog engagement gearboxes

Have a look at this Imp engine video to see what they stick in their motors.

That makes A-Series race engine building look easy, especially when you take parts availability into account.
