Hi Tony,
As you probably know I have fitted 4 jet crankshaft lube on your blue chummy and on 3 other cars but I have never exceeded 5000 rpm and then only occasionally. Never raced any car, only the blue chummy in about 1970 and unfortunately ran a big end but the white metalling was poorly executed and it had 2 jet lube at the time. Some people on A7 Friends think it is unnecessary but it gives me peace of mind zooming up hills in the Peak district. It is not too difficult a job to do it. The method is in " Design for Competition " I think.
