Just look at the link I posted a bit earlier.
What I see there is a 416 running the stock intake and ex manifolds, a 650 carb, and a tiny cam........ in a car that’s seen hundreds of passes down the 1/4 mile.
They have sorted out the timing, jetting, launch technique...... and shift rpm....... and the best ET’s come with the shift point between 6000-6300.
It’s certainly not “all done” at 5k.
My friends stocker is 412”, has .420 lift, and heads that are smaller than the legal limit of 160cc, and only flow about 220cfm.
On a good day it’ll run 6800rpm through the lights(over 128mph).
Like I said, I’m just playing devils advocate.
I don’t expect to change anyone’s mind.
I just know what Ive seen from testing motors on the dyno since 1990, and none of it has indicated that a build like this “has to” peak at under 5K.
I mean....... unless some minuscule cam is used, or the valvetrain can’t keep up.
