74GTS, way off-subject for this post but the possible weight savings from the engine are even more extreme if you also include the almost-mandatory aluminum intake manifold (-30 lbs over stock iron), aluminum water pump (another 8 lbs), a mini-starter (-6 lbs), and a tuner Holley that uses aluminum float bowls & metering plates in place of cast zinc (-5 lbs). I also duplicated the stock steel-plate alt/AC/idler pulley bracket in 1/4" aluminum (-16 lbs) and use a Sankyo rotary AC that is 22 lbs lighter than stock. The law of diminishing returns intrudes about this time, but I measured a whopping 120 lbs lost from our 351-C assembly.

Lightening up all areas of the Pantera has been an ongoing project for me since about 1990, and our stock-to-the-casual-eye '72 L model runs right around 2675 lbs today, licensed & ready to drive. Factory-stock was 3250 lbs on this car when I started the exercise. All this was written up in illustrated POCA Newsletter tech suggestions over the years, and free downloadable back issues (back to 1979!) are available as pdfs for members. Now, back to our regularly scheduled Forums-
