sequential efi on 440?

[Mike Williams]

I'm building a chrysler 440 for in my 4x4 picup and would like to use
sequential efi. I sent mail to Electromotive and Felpro. Have'nt heard
from them yet. Right now I'm triing to decide on the cam. Called Comp
cams for advice, they said most mutiport efi makers don't recommend a
cam 220 degrees duration @0.050. Is this right and why?  P.S. Most of
the material in this group is over my head but I'm learning. Thanks to
you all...Mike
