Hmm you could go a boss, sure you'd have alot of kw but you'll have nothing down low. But if you want a 5.4ltr i'd say throw a 3v in there, cheaper and heaps of power down low I honestly wasn't too overly impressed with the boss motors, i prefer my power right from when i put my foot down not 50m down the road when im already doing the speed limit

Here's a 4.6 Modular vs. a 302 Windsor



(the 5.4 is of course bigger again).

Thats a pretty intense difference. If the gods allow it and the modular unit fits an e-series it's St.Machine mag material. lol...

WERD!
