Scott, I suspect from the name that you might be doing something with a
Cad motor...?  Just curious.  I am adapting a '95 5.7L truck TBI to a
Cad 500 (also using the 4L80E trans).    I was planning to use the
Edelrock aluminum intake with an adaptor for the 2-bbl GM throttle body.

However, I wonder if I could use that '75-'76 Cad DPFI intake instead?
Are the injectors actually located at the intake ports?   I wonder if
the runner-design on that intake is better than on the stock carb
manifolds (wasn't too great).
Now if only I could find one of those DPFI setups....
