And, I believe it the 283 in 1958 Corvettes that first made more HP (290) than cubes.
It was actually the '57 solid lifter Feul Injection 283, which was available in any '57 Chevrolet Passenger car and the Corvette. However, it was advertised as being a "283 hp 283" because of the magic "1 hp per CID" being a good sales gimick. The actual out put was 290, which is what the '58 version was advertised at.
