1966 Lesabre convertable

I am looking at buying a 1966 lesabre convertable anyone have any info on a 66 they would like to share?

Engine size I think it is the 340, right?
Any things I should look for, or things I should be aware of before jumping into a project like this?

Thanks

I'm only 9 years late to your post... I happen to own one.

If you ever read this, let me know if you got your ride.
