This has probably been covered numerous times before, but how important are the frame blocks in a model T? I realize the steering shaft block at the pitman arm is extremely important. But how about the ones where the engine mounts are? I have cars that do not have the blocks and a couple that do. I see no difference in how they operate nor have I seen any problems in those cars where the blocks are absent. I realize that they are not that hard to install. I was just curious if I need to put them in if they are missing now.
Thanks
Those blocks help prevent frame cracking. Here is another thread about it...

Can you imagine Henry putting them in if they weren't valuable?
Dan Treace posted drawings of the blocks last month, just in time for me to make a pair and install them.
Ford discontinued these blocks on the TT's. The Blocks weren't used on most the 1925 TT's. The bolt however were kept until the 26 models when the block and the bolt both were discontinued. It seems Ford said that this mount was too rigid and needed to move to prevent metal fatigue of the mounts.
The wood blocks in the frame controlled sideways motion of the engine. It's easy to see how the 1926/27 angled straps going from the new hogshead attachment bolts in the engine down to the top frame engine mount bolts could do the same job without the risk for metal fatigue. The hogshead attachment bolts weren't introduced until july 27, 1925 with the 1926 model and the angled straps came later in the autumn of '25.
