Sam, always like reading your posts, and have huge respect for your products. Having dabbled in building 'upgrades' (a term of convenience), your/our goals are generally not financial, or to fill up empty time, or to 'see if we can screw something up', but indeed to use present-day methods to correct, update, improve. If not for this, none of us would upgrade tires. Or use iridium plugs. Or high torque starters. Or more impervious hoses. Or better fuseblocks. A staunch preservationist may certainly insist that OEM is 'better' in all regards simply because of the "O" in that appellation, but 'better' to those intent on improving function choose otherwise. As a result, My Pantera doesn't overheat. And it handles as good as anything with 20 years of its age. My 328 doesn't flood the cockpit with heat, is less noisy than its OEM counterpart, and outhandles the NCT-equipped tires of its youth. My E-type runs cooler, starts better, stops faster, and is more reliable because 50 years of smart people have enthusiastically addressed its period-correct shortcomings. My 911 has air conditioning that works better, eats less power, and is less drip-prone than the one blessed by Ferry in 1985. No one at Ferrari (Porsche, Ford, et al) was "wrong" when they made their best efforts for the showrooms. It's just that modernity has "righted" what would've taken a time-machine to have done in the first place. Long live the improvers. Thanks Sam.
