again, thanks for all the inputs!!! I am new to a 302.
When I wrote this thread, I was already corrupted by this 1968 Road and Track article below that unfortunately gave me the mindset these engines were safe up to 7500. Articles like this one maybe are to blame why so many Z/28s blew. You just get a mindset they were designed to be robust up at the high RPM range of 7000 or so.
Learned alot in the past days.
