Also, what hardware is used? Is that pivot threaded or pressed into the 216? Ive seen some pics from pre68 Dave, not sure if he re-uses the pivot, or fabs it.
Thanks!
Oh, the engine runs smooth, except for a vacuum leak, the alignment ring at #1 cocked as it was going in. Had to pull it off to drill for the pivot anyway, but got to hear it run! | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | Sorry I did not get back to you with the measurements. I am on vacation for another week and do not have them with me.
Anyone with a 1937-60 216 or 235 could give you the front pivot measurement.

The mounting hole should be 12 9/16" from rear of block and 4.850" down from the deck of the block.
Yes, they are threaded in.

The one I have access to doesn't. I've soaked it with penetrant, heated it etc. I don't want to scar it. Are the early ones also threaded? Are they available? | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | All factory bellcrank pivots have a hex base. What pictures are you referring to? In the picture in THIS LINK you can see what the 1941-62 pivot looks like, 1938 is similar but has a bigger hex and a nut on the outboard end to hold the arm on. The hex in the block in this picture is a 1/4" pipe plug I used to replace the missing mounting position on 1960-62 engines.

That does not have a hex, it is driven in.
When I get home next week I can post some pictures of that conversion I have done.
Can you post a picture of what you have?
