Interesting reading

Does anyone have any real data on the yield strength of the bolts being
suggested versus stock ones??.

I have been caught before. I am using some Mitsubishi conrods in a
stroked 2 litre GT6 racer. I had their bolts tested to find they are the
same yield strength as the fancy ARP ones.

I have built dozens (maybe hundreds) of road & race triumph engines over
30 years and never seen a main bearing bolt fail. I've tossed out quite
a few from thread damage or other visible defects, but the majority are
fine.

Further, with regards to 'aircraft" bolts, many are a grade of stainless
steel which can be quite brittle, and are not suited to this type of use

Does anyone have any real data to share??

thanks
