GLPerry, we have 250EFI here in Brazil for a long long time. But it's a multipoint set up, distributorless system, the intake manifold is a big piece, crossover the engine and the throttle body is on the pass side. Works very smooth, but is not all that powerfull, just 168HP, and has a flat cam, the engine is not just a regular 250 with the efi, is a new set up, longer rods, a new head, etc... out of a running vehicle worths almost nothing, since gas here is a li'l expensive. Some kiddos are swapping them on earlier L6 cars and trucks, but performance is not all that great, still a gas guzzler, just has a terrific look. I've been lloking at an engine like this for a while, and I think that if properly tuned (requires a new intake made to fit the different port arrangment in the new head) and a cam with more LDA would make for a good torque and low fuel consuption package.
