Why were these production new cars not viable? Factory HP ratings too high maybe? Thats the manufacturers fault, not racers or NHRAs.

He states the reason in his post.
“As the OEM's have improved the efficiency of the engines there are not the same gains to be had as older combinations.”
The new manufacturing process and standards has eliminated 30hp by turning a screw and 60hp by rebuilding a slapped together carburetor and adjusting the cam or machining with better tooling.
Plus with standards with SAE there is less “slide of hand” items to overrate/underrate due to insurance, advertising etc. HP ratings have to repeatable and within a window.
