My guess is that part of the difference in value was that the additional "35" horsepower came with a "wink" from the boys at Chevrolet. Just my $0.02 (pre-tax, of course)

totally different animal... 2 bolt main in the 390 car, 4 bolt in the 435, no tri-power in the 390, hydraulic lifters in the 390 too, solid lifters in the 435. A nice performance car, but nothing like a 435!
