440 rpm

[74duster]

What is redline for a 440 with a stock bottom end? In this case its a mid seventies engine.

stock oiling is the limiter.

I wouldn't turn one over about 6500 before seriously thinking about some oil system upgrades.

Works for me, thanks!

Also if your still running the hydraulic cam with the OEM stamped steel rockers she'll probably start noseing over at 6K.

I'm not sure what you mean by noseing over. Are you talking about power loss?

No, you're at the top of the horsepower curve and going down the other side, basically you're just wasting HP. You can usually feel the car at this point isn't accelerating as fast as before the peak and the engine is probably coming close to floating the valves at 6200-6500 rpm (with a tired stock valve train) and you don't want to go there.

Redline is the last rpm before it explodes. That's what any engine's redline is. I've seen performance built engines who's redline was 3500 because at 3600 they blew up. I'm not sure of that's what you were asking tho...
