Wow, what a wonderful post. My son and I have been building are first project together a 66 Fury3 as well. As of now we are about 95% there but still needs wiring and after the first crank up noticed a dead cylinder;( Did a 505 stroker through 440 sources and really hoping it's a ring. The amount of fabbing you did blows my mind and your car is beyond beautiful.
We still need to have ger painted someday, but for now who cares right;) Few questions for you, is your hood factory or aftermarket bc I thought ive seen fiberglass hoods with hemi type scoops for 66 Plymouths. Also, any idea on the largest tire on a 15x8 rim will fit? As far as upgrading the stock rear suspension, any pointers would be nice and possibly upgrading the front as well. This car will be more for around town vs the strip.
