Kevin, IMHO, I would opt for building a solid foundation. Purchase an aluminum Pond or CSX block with some nice internals (rods, crank, pistons, etc.). The EFI can be added later. Also, the Dynatek system for an FE is $7000, not $6,000, unless you're receiving some sort of discount and then there will be some incidentals like purchasing the air filters, adding the O2 sensors into the sidepipes, etc. The aluminum block will save you 100-125 lbs from the front end and will make driving your Cobra more enjoyable.
