If you really want to drive this car much, you are going to be very unhappy with a 216. They are not on oil pressure motor. They use scoopers on the crank to splash oil around. They will not take any abuse at all. You'd be a lot happier with a 235 that has a full pressure system with pump and noone could really tell just looking at the motor that it was a 235 as the two motors are very similar on the outside. Take my word for it. I found out the hard way in 1962.
