What do you think the RPM threshold is for these engines. I'm talking a rebuilt 307. What RPM can you get to before you start to do damage to your engine. Because i have a 3.73 rear end in my pickup and if I ever want to see what kind of speeds I can reach and how fast I can than I need to know what RPM I need to stop at before I start damaging. I know that at 60mph it'll only be about 2300-2400RPM. Are we talking 5000 or is it 6000 or is it only like 4000?
