In your case Will, sure it'll work...hehehe...you probably need it. But on
these stock R/T's (or 5.2/3.9L engines) that's just too much. Going by the
calculations that I have for max CFM rating, a 360 turning 600 rpm requires
688CFM.
Here's the formula: ((Max RPM * CID)/3456)*1.1 (The 1.1 is for that extra
air flow...just in case.
Granted, this would depend on Cam, Heads, Exhaust, S/C or Turbo, but that
calculation is for a "Bone Stock" configuration.

If you were trying to have the biggest "dick waver" then yes, but if you
actually expected to be able to prove yourself on the track, then no. I am
with you on this one Bernd. I have a 53mm bore tb, but then again, look at
what all else I have done to the 408. I had the heads, intake, exhaust and
even a blower put on. My engine works fine with this setup, as the slips
prove, but if I didn't have the blower, then the 53mm would be way to big,
it
would bog off the line and would then run lean on top end as the injectors
couldn't provide the fuel. Even if the injectors could provide the fuel,
the
motor wouldn't be able to effieciently burn it, so you would end up running
rich and losing performance. If you go to Holley's website, they have a
graph on there somewhere (sorry, can't remember where) that will tell how
many cfm per ci that you should need. The chart applies to n/a only, but it
is the max that your motor could use. It is rated at 100% effieciency,
while
most stock motors probably run 80%, if that. You have to do alot of work to
get near 100% and the only way past that is to use a blower or turbo. Just
something to think about.
