There was a 2 valve and 4 valve 390 made...
The 390, with 390.06 cu in (6.4 L) true displacement, had a bore of 4.05 inches (102.87 mm) and stroke of 3.785 inches (96.14 mm). It was the most common FE engine in later applications, used in many Ford cars as the standard engine as well as in many trucks. It was a popular high-performance engine;[35] although not as powerful as the 427 and 428 models, it provided good performance, particularly in lighter-weight vehicles. The 390 cu in (6.4 L) 2v is rated at 265 bhp (197.6 kW) @ 4,100 rpm, while the 4v version was rated at 320 bhp (238.6 kW) @ 4,100 rpm in certain applications. Certain 1967 & 68 Mustangs had 390 4v engines rated at 335 horsepower (250 kW), as did some Fairlane GTs and S code Mercury Cougars. When the 390 was first offered for 1961 model there was a 375 horsepower (280 kW) High Performance version that featured an aluminum 4bbl intake manifold, cast iron "header" style exhaust manifolds, 10.5:1 compression ratio and a solid lifter valve train. Many of these cars came with an aluminum 3x2bbl intake manifold in the trunk that was meant to be installed by the dealer and raised the engine's output to 401 horsepower (299 kW).
that's from wiki
i don't know anything about 390's dough.
someone explain 4v vs 2v? like 2 intake / 2 exhaust
or is it refering to the carb. I've heard of 4barrel/2barrel
P.s. completely ignore the fact that I own a girly version of this car
