03-04 4Valve mach motors are aluminum block, not iron like there 03-04 cobra brothers. also i just purchased a bone stock 05 gt wiht 2000 miles on the ticker. my buddy has a 99 aluminum block cobra stock with jlt cold air kit. they run pretty dead on. the 4 valve heads are sick as far as air flow but my stock 3v has the varible cam timing which is nice. i don't know how an aftermarket wiring would address the cam timing. i like the ls idea but i personally could never put a bowtie in a ford. i think 2000 is way less than you can get a 3v motor for right now but thats just my .02. good luck!
