Selecting power valve method Holley 4160
A converter will affect power valve timing??
That’s dead wrong.
Look, This is a daymn fine STREET 318.
This is NOT a race motor.
Op has a 3000 stall, on a high-pressure 318 with Magnum heads, in, I'm assuming, a 67 Barracuda. With this combo, the engine is very lightly/almost extremely lightly loaded, below that stall; and, I took the liberty of assuming, that he was not running hiway gears.
I mean; I'd probably be running 4.30s, for 60mph= ~5100rpm in Second gear.
But I'd think, OP is more likely to be in the 3.73>3.91 window.
I mean he already told us that it idles at 15/cruises at 22 inches, so it's got a lot of low-rpm torque; and,
I also assumed that he would be jetted too rich, cuz every 318 owner I ever knew, does it.
So then, what I said was;
"With a 3000 stall, the PV-calibration won't hardly matter."
I did NOT say that it does not matter at all.
I said, "won't hardly matter".
cuz;
OP's carb is rich enough on the Primaries, it might not even need a PV hardly at all. Please notice, I said "hardly at all"
Then; OP tells us that he's running 72P/74S, thus confirming my thoughts.
Notta chance does that 318 need a 72P. the 66P was probably real close, and the 72 is a good starting point for the Secondary, and now, the 10.5PV is gonna fill the gap, after the Primary runs out, just like it's supposed to.
I mean,
I suppose,
you mighta missed the part about
" won't hardly matter".
Tell me I'm wrong.
