3.1L 240Z triple weber carb tuning (w/ new Stahl headers)

A collection of short clips / butt Dyno runs while tuning the triple Webers on my 3.1L 240Z. Open Exhaust. Unfortunately, I didn't have the benefit of an O2 sensor / AFR. All in all, I was pretty pleased with the final results, the new headers have really opened up the head's flow potential. Sounds good, too! :)

untuned and unmuffled idle, 240Z 3.1 stroker
Quick demo of the new race headers (Stahl), at no point does the engine rev above 3k rpm (despite how it sounds at 1:25). Other coincident upgrades include titanium valve spring retainers, single valve springs (outer springs only) that the cam was profiled for, and a crank/damper/flywheel balance for 10,000 rpm. And yes, that's coolant on the ground during the idle portion. Evidently I didn't tighten one of the thermocouple housings all the way. Oops. Between moving and other logistical challenges, I barely had the time to get the new race motor installed and minimally operational before sticking it back in the trailer for 6 months of storage, after which the engine seized. :'(
