I've seen 0-60 times listed for the 1974 GTO at 7.7 seconds, which was probably with the stick shift. Could you get a 4-speed with these, or just a 3-speed? That's really not far off from the original 1964's 7.5 seconds, with the 325 hp (gross) setup of the 389 (dunno if that was with a 4-speed or automatic though).
 
Both of 'em also did a ~15.7 second quarter mile although the '64 was doing 92 mph, versus 88 for the '74, so I guess that's an indication that the '64 was still a much better performer at higher speeds.
 
Not a bad car at all, considering the timeframe, but they just should have called it something other than GTO.

The $195 1974 GTO package came with a 3 speed floorshift, with Hurst shifter as far as I know.
 
  Some of the early Hurst Olds Cutlass were special cars too, later ones were pretty much paint & tape only.

1967:
 
Yenko ordered L-78 equipped SS Camaros and swapped in the Chevrolet Corvette's L-72 427 in³ (7.0 L) V8. The cars came with a 4.10 rear end and heavy-duty suspension. The exact number of cars produced is not known; most estimates are around 50. Yenko also installed a fiberglass replacement hood similar to the "Stinger" hood featured on 1967 big-block Corvettes.
 
 
 
 Don Yenko's Camaros were equipped with a 427ci L-72 in them with either an M21 or M22 transmission. The horsepower was rated at 423 hp (315 kW). Yenko Camaros were not allowed to race for Chevrolet on the drag strip because they were not made by Chevrolet. Chevy's answer to this was the Copo Camaro, or Central Office Production Order, in 1969. The Copo Camaros were equipped with the same 427ci engine and were allowed to race for Chevy.

The 1975 Chevy Vega Cosworth. A marriage between GM's 1970s rear drive subcompact and the 4 cylinder dual cam 16 valve expertise of English engine constructor Cosworth. In 1975 32 out of the 33 starters in the Indy 500 used a Cosworth DFV V8.
    
  The Vega Cosworth never really lived up to expectations because of pollution controls, but an interesting curiosity today.

Rotaries were pretty strong on performance in the 1970-75 smog era.

Mazda had a *lot* of trouble making the rotary engine ready for "prime time"--they burned oil and they sucked gas, and sometimes they would backfire so badly every war veteran within ten blocks hit the dirt.
 
To Mazda's credit, they stuck with it, and replaced a sizable number of rotary engines under warranty, and BEYOND warranty, and I'm sure it cost them a pretty penny.
 
Eventually, in the early 1990s they developed that rotary engine into the rather magnificent Mazda RX 7 Twin Turbo, which was, and still is, a formidable sports car and very quick indeed.
