Back in the day my dad had a '67 Cutlass Supreme, boy what a car! I got my license driving that beast (parallel parking was FUN!). I've been looking for one to buy, either a CS or '67 Vista Cruiser but they all seem to have some form of the 330cid motor. The car my dad had had a motor different than any pictures i've seen of a 330 from that era. The 330 air cleaners say Jetfire on them and I'm pretty certain ours said Rocketfire. I KNOW it also said "ULTRA HIGH COMPRESSION" and required premium fuel. I'm thinking it was a 400 and I know that car would FLY even with a 2 speed auto (like they say about the PowerGlides - 2 speeds, fast and faster!). The car had power steering and brakes (4 wheel drums) and air, but manual windows. Can anyone help me identify what the motor was? Unfortunatly dad got rid of the car in the early 80's and I'm sure it been recycled LONG ago.
