What size motor is in the 1966 Buick LaSabre

This should help. http://www.automobile-catalog.com/make/buick/full- size_buick_6gen/le_sabre_3gen_4-door_hardtop/1966.html

By the way, pop up the hood to see what engine you have or look at the door jam. Probably, you don't have an owners manual? Fat chance, I know, but, you can download one. (LOL).

Matthew, do you own this car or just curious and thinking about getting one? If you have the car, how does it run?

Which configuration, there's a few here.

Could of been a 401 v8.

I actually have one in my garage and my dad left it to me. It had 7 miles when he bought it and it has 72,800 miles now. Has a 401 I had rebuilt last year when it began to leak oil around the main seal. Still runs fine and has the original am radio in it.

72,800 miles? Really? . Was this thing in a museum?

No. Kept in a garage by him as a "toy". I have the original sales sticker from the window showing he paid 4,259$ For the car. Shows a 401 v-8 with 273 hp on sticker. Doesn't show dealer installed at all. It is a "limited" according to that paper from the window when it had 0 miles ..

A toy, you say. Yes, well, it's definitely a big gas guzzler! Unfortunately, many of these old 60s cars by today's standards are just more nostalgia than anything else. Sure, they were muscle cars in their day, the model technology of newer cars have made these behemoths seem lethargic with their four valves per cylinder and naturally aspirated engines breathing easier. Plus, add in greater fuel-efficiency and voilla these cars look extremely dated. As far as I'm concerned, it's much better today than living in the bad old days of polluting vehicles and extra stops at the gas station. Not to mention, these old cars lack air bags, vehicle stability control, better handling, not as quiet as modern cars, etc. SO, what's your plan for this car?

To pass it on to my son when I die. He wants the car but he can't have it until I am gone. I put 10 miles on it every week just on Sunday's. Take it down the highway and back. Everything is original and still functions.

How old are you ?. So, when will you pass this car along?. That's a lot of insurance payments over the years. Do you think the car will be worth doing this and what's it costing you annually to maintain this car? How does it drive? Can you post a picture, please?
