Not to burst your bubble but Pontiac only made 421SD's for 3 years, I believe 61 thru 63 and it was made for the Catalina's as a "drag race" factory car, they had items like "swiss Cheese" chassis and other things to make them extra light. There were no 64 GTO's built with that engine and I think until 1970 GM would not allow anything over 400CI in there mid sized cars or "pony" cars, although certain dealers could order big block chevy's out the "back" door if you knew the codes.

The 64 GTO had the 389CI motor. Pontiac brought back the SD name in 1973-4 in the Trans Am, I had a 73 455SD Trans Am, (till stolen) LOVED that car!!

Cmon guys, these old muscle cars aren't about 0-60 times and better handling. It's about how you feel when you hear the coarse rumble of a raw American V-8 the second you bring it to life. It's about the tire-burning, put you back in your seat, testosterone induced thrust that lets everyone know you're a badass with good 'ole American steel style. When you drive a GTO, an SS, or a '69 'Stang people stop, stare and wish they had one of their own.

There's no comparison.
