Tim:
(1) 1.5" - 2" cut from the plenum divider is more than enough to really
wake up the V6 from 2500rpm on up to the redline.
(2) 48mm for Normally aspirated and 50mm for Supercharged.
(3) 24# injectors are too big for a normally aspirated V6...if you're
going to change them, switch to the Ford Motorsports 19# high-flow
injectors.

Subject: DML: V6 Intake manifold modification????
I just bought an extra intake manifold and want to know how I should
modify it. I have been reading the archives and just have a few
questions. First off my truck has accell coil, brass cap and rotor,
autolite's, cold air intake, modified TB, exhaust, and soon to be
car-sound cat, powertrax locker, and Jet Chip. I know I am going to
smooth the runners and radius the injector ports. How much should I
take the plenum down. I have heard no more than 1 1/2" and 2". What's
better for my case. I also want to know should I change the TB. What's
better, the fastman TB or the F&B TB? What size bores should I go to
48mm or a 50mm? Is there anything else I should do before I modify my
intake? I will be adding 3.92 gears soon if that info helps any. I do
not plan on putting a SCer or nitrous but am open to the idea of
changing the injectors to 19# or 24#. Thanks!
