Re: 351w lighting
I'd recommend new injectors (24lb) and a Lightning-specific computer. I never trust old injectors on a new motor. I believe the Lightning computer would have much better timing curves and whatnot. However, instead of going through the hassle of all the Lightning-type stuff, just get aftermarket intakes, Lightning throttle body ($50 on eBay all day long), and get some GT40 heads from a 1996 Explorer. It'd be better than a Lightning motor.
