440 cams and efi

[Maxt at nucleus.com]

I read the posts on the 440 efi, and the cam questions, Hughes engines
makes chrysler specific cams for the 440 which take advantage of the
440's larger lifter area. The larger lifter allows you to install a cam
with larger lift, less duration and overlap, retaining vacuum and idle
quality . Most cams are chevy grinds altered for other engines, and are
not particularly suited to chryslers and will make the engine
underachieve. This is why most Mopar racers don't publish their cam
specs, they have done considerable amount of research to come up with
their own "dodge" cam, and it usualy helps put the engine a notch over
the competition. A dual pattern cam is probably the best bet since 440
heads are so restrictive around 450 hp, the exhaust needs a little help
to fully evacuate the cylinder, the intake side can have lots of lift to
help with the small ports. The mopar performance porting kit for the
heads is the best 20 bucks you'll ever spend, it concentrates on the
bowl area of the port  and around the valve seat, just don't touch the
short side radius, the 440 head needs all it can get, on a good engine
the porting is worth about 50-75 hp. 
 a question of my own now and that is whether or not to try installing
454 tbi system on 440, would the computer handle the 14 ci difference?
how about gettting a 7.4 vortec system and grafting it onto the 440?? Is
it possible to control 2 throttle bodies with one GM ecm?? 2 throttle
bodies on a low riser tunnel ram would be pretty trick
