460 Redline

What is a good redline for a stock 460 from a 78 pickup? The engine is solid and rebuilt, but I am curious how fast it should turn. I am about to buy an in-dash tach and I don't know whether to buy the 0-6000 or the 0-8000 version. I have no intention of turning a stock 460 8000 rpm, but is 5000 or 6000 too high?

I broke a rod which broke the block, head and crank at 5500 rpm.

Stock rods? That's a whole lot of rotating mass, Boss 302 it is not! I'd keep it to 5000 max.

i would almost guarantee that a stock 460 would not turn 8000 rpm ever. i would stick to the 6000 tach and follow Bern_F150_4x4's advice

If I had a choice I would put a 5200rpm rev limiter on a stock 460 anything above that is really pushing your luck so as the others said unless you plan on upgraded internals soon just stick with the 6000rpm tach

The engine makes max horsepower at about 4600, why take it past max horsepower? It just abuses the rotating mass and improves the performance none at all.

Great answers. If I upgrade the rotating assembly in the future, I can always buy another tach! Thanks guys.
