FWIW, a few guys have done this in the past, to 351-C tunnel-ram intakes, 
with unknown quality results. The only problem I've heard of concerns the 
machined orientation of the injectors once spigots are welded into the runners. 
The nozzles ideally should be aimed so that the spray pattern from each 
injector is down the port directly at the backside of the intake valve. Most of 
the weld-ups are not oriented this way, possibly because it results in odd 
angles for injector tops that force multiple fuel rails, or protruding fuel 
rails that interfere with other engine parts. So driveability and mileage 
suffer, but some of the conversions were for street drag racing. Making your 
own EFI manifold to work well on the street is not a job for a gas station 
TIG welder, apparently. Good luck- J Deryke
