| RE: Where should I set my redline on a stock 390? |

The FE valvetrain is pretty heavy. If you've got stock, old valve springs you'll float the valves pretty quick and run the risk of dropping a valve if one of them breaks. If it were my car, I would replace the springs and crappy stock retainers and locks with newer stuff before I ran it hard.
Also consider adding an extra quart of oil. The stock FE oil pan isn't baffled very well and when you accelerate quickly it runs away from the pickup. I've run mine with an extra quart for a long time--you can't even tell its in there, just cheap insurance.
With replacement stock springs and a stock passenger car cam you'll probably run out of steam around 5000 max. With a hotter cam and a solid bottom end a 390 will spin to 6000 safely. |
