'64 GTO Pure Oil Performance Test Car

Built specifically for competition

Some creative thinking to get it to market

This new GTO came with the same rugged 389-cid V8 powerplant as used on the larger-sized Pontiacs, but to give it even more potency, the cylinder heads were from the 421 H.O.. The standard version came equipped with a single four-barrel Carter carburetor, with power rated at 325 hp at 4800 rpm.

The “Pure Oil Performance Trials” event took place at Daytona; only this time around testing was done under the watchful eye of NASCAR officials. It had to be on the “up and up” and no hanky-panky with engine swaps or special dealer-tuning tricks.

The optional “3 Deuce” engine used three Rochester two-barrels and was listed as having 348 hp at 4900 rpm.
