I got my old 124 back together again today and went for some driving. It's not the fastest thing ever, but it sure is fun to wind out through the gears.
8K tach installed instead of the 9k tach I'm familiar with, so my shifiting today was a bit early 
I've found benefit in running to 9k+ in 1st and 2nd, even though the power is tapering off.
anyways, enough rambling:

Some more carb tuning with a wideband should yield better results (long overdue)
With correcting the speedo (it's not accurate due to trans swap) and looking over the video I'm right at about 7.5s 60-100. Not too bad for an "antiquated" 1756cc NA.
Any other vintage Fiat owners here care to share some in car footage?
(hint, hint Hussein)
