Safe RPM for an LQ9 short block That is the question. What is a safe RPM for an LQ9 to see frequent visits as a street motor. I am picking a cam for my naturally aspirated project and I am going to pick one that won't tempt me to push my luck.

I have seen many threads about safe RPM for an LS1 but none for the LQ4 and LQ9. I assume since the pistons are bigger and heavier that it might be wise not to spin the stock short block as high. Your world experience is very helpful.
