Starting RPM
OK, I figured the knowledge bank here could help me with this one.
Given a stock 1978 460, with a stock starter, a fully charged battery, and a good electrical system.
What would be a good estimate of the RPM while starting, before the engine fires?
Thanks in advance

It doesn't take a specific RPM to start an engine. The starter needs to rotate the engine enough to build some compression for the fuel/air mixture to ignite. I sometimes hear that you need to be in the 400 RPM range but that is fast if you think about it. When you do a compression test you'll see the guage bounce every second or so, that equates to 60 RPM. You'll need more torque from the starter to rotate the engine faster.
Is the engine barely turning over or something?
