Stock internal 318 redline??
similar specs to a 340/360 cam*
the 340 cam was a 268/276/114
With the matching 340 springs it made peak power around 5000. More often than not, the springs would start to give up around 5400. But with a lil more spring, would get closer to 6000.
Your engine has at least two or three so called, redlines.
The first relates to piston speed.
The second is the so-called valve-float
The third is actually the optimum shift-rpm.
>I don't remember the formula for piston speed, but for a 318, it's probably way up there, past valve float.
>Valve float you can usually feel when you power into it, and you want to stay away from that, cuz if the valves get into the pistons , they are done. This varies with the springs and lobes.
> Optimum shift-rpm has already been explained.The thing to remember is with a Chrysler automatic, it will be different in each gear, cuz the splits in the trans are different.
On the street with 3.55s, it matters not a whit; just pick something below valve float and let her buck.
