They are shorter on the front/taller in the rear. I'm speculating it's designed that way for pinion angle, I could be completely wrong. It could also be to support the leaf pack at a better angle due to the height difference over the regular 1.25" OEM blocks. Maybe it's an axle wrap/wheel hop issue. Whatever it is the SVT team did it and I'm pretty sure they wouldn't have wasted their time without some reasoning.
The other question is if Ford did it that way for a specific reason then why don't the aftermarket companies who make the 3" and taller blocks? I've not seen/heard/read of anyone having issues with shock travel, pinion angle or leaf packs when running those 3" blocks.
By no means would I consider this a complete explanation...it's merely one data point. Read #5
