new engine

[Mark Eidson]

What type of intake manifold are you looking at?  I assume you are going to
use some sort of EFI.  Are there manifolds similar to the 5.0 available for
the 351W?  I've seen production manifolds in boats that look like 5.0 units
but are 5.7.  Would these work on the older 302/351 style heads?  If so
where can one purchase them?  I'm using a Performer RPM with a 700 CFM
Holley Digital Pro-jection 4di with laptop control on my current engine.  It
has a crane hydraulic roller cam, @ .050: I 216 @ .533 and E 220 .544, with
9.0:1 compression with rebuilt, hand ported 64cc cast iron heads.  I have a
351 block sitting on the garage floor and want to make a sequential port
injection system for it to bolt into my current setup.  me
