All (esp. Don) -

    With the Ford EFI, it doesn't matter too much where it comes from (302
vs 460), just so long as the system could do originally what you want it to
do on your Mopar. So basically, as long as its an eight cylinder sequential
system, you're golden once you change a few things.
    I'm using the 302 system on my 413. The 302 came with 19lb/hr injectors
which can't very well support a big Chrysler. I'm going to use 24lb/hr
injectors. The only thing you have to do is tell the computer the important
new details: the displacement, the injector size, etc.
    Whether you do this on a 460 computer or a 302 computer, you'll get more
or less the same results. The only big differences to expect are the spark
and fuel tables as the 460 was found in trucks and likely tuned toward low
end torque whereas the 302 came in the Mustang, among others and is tuned
more for the top end. You may argue that the map for a 460 is already close
to a big block Chrysler map, but due to its lack of popularity, finding out
where things are stored in a 460 computer (they won't be at the same memory
address as in the popular 302 computer). But just about every secret has
been gleaned from the 302 code. Thus, you'll have a much easier time tuning
the 302 computer.

for 7 yeares at provincial trade school.
> First thing to remember is the efi doesn\t know or care what type of motor
is under it so you can fit any system if you have it complete with ease.
> Watched a former student make a double  throttle body  top for a mustang
efi manifold on his 302 and then stuff the whole deal into a Capri. It
worked good enough he had some one come along and buy it from him.
> He made the manifold top from 4x4 box tubing for the plenum and steel
tubing of the proper size underneath.
> For a big block Mopar my gut instinct would send me looking for a 460 Ford
truck system . I know it would handle the airflow and fuel delivery and
would be an excellant jumping of point . After that an aftermarket computer
or power chip wpuld probably do the job.
> Also have a German Hot rod magazine with an article on how to convert an
early hemi Hilborn unit to Gm off the shelf injectors and a britsch made
computer.  I am not sure where it is right now but I know I did not throw it
out. . Bought it in the Worms Deutschland train statrion as a Present to
myself on my 50th birthday.
> However, I thin k Cam design is an area we need to look into as well.
> We have with the mopar cams the ability to open the valves at a tremedous
rate due to the .904 lifter diameter. Add to that a set of 1.6 rocker or
even the 1.75s Erson used to make (and hopefully still do) for the big block
mopar power we could run a cam with high velocity action with a duration at
.050 of say 231 and yet have the duration at 200" (or even .100") meet or
exceed our current big  pro street cams. I know it would need a little
tweaking but I want to play with it to see what happens.

However It is not likely to happen.
