If you convert to front steer you can't use the the stock steering arms/ball joints. The Ackerman will be backwards causing toe in on turns, not good. So again your back to swapping everything. Not much of a gain. Sure a little extra header clearance would make taking it apart easier. You loose a little weight with the rack. But not enough benefit to come even close to covering the cost. You could almost buy an aluminum block for the cost of the conversion.
