How much NA power are they good for? .990 diameter, 4.25 bore, 515gr pistons. Will they be good at 750hp and 7000rpm?

It's not optimum, but it'll work at that rpm and piston weight....

Do you know what kind of material the Pin is made of?

 

[chadman]

Material is 52100

Typically a bearing steel but JE and Wiseco use it I think. Probably others.

 

[chadman]

They are Wiseco pins

I have run them at that power level and RPM for a few hundred 1/8 mile passes with no issue.
