I'm going to put a 5 speed behind it so I can use it for cruising. What would be a good rear end gear. 2:96 or 3:08? I've been told that the 216 doesn't like running at the higher RPM's Is there anything else I should be aware of as far as driving.
If at first you don't succeed, get a bigger hammer.

A 216 won't have enough torque to run 5th. gear with either of the ratios you've mentioned, and I doubt if it will even pull right in 4th. gear direct drive. With the dual carbs, you'll be lucky to make it run at all unless it's revved up. With the oil clearance adjusted properly, a Babbit-rod engine will handle 2500-3000 RPM without a problem.

If your going to drive in areas that have lots of steep grades you may want to rethink your choices. | | | | | Joined: Mar 2011 Posts: 457 Shop Shark | | Shop Shark Joined: Mar 2011 Posts: 457 | I would love to have a five speed with my 216, but, I agree with above comments. A stock 4:11 is perfect, but maybe a 3:55, 3:70 etc. would still give you some pull, and more economy. Forget the 3:08!
