All Small Six Back in the Saddle

I will be excited to see if the roller lifters will go into the 200 block.
If not, I have an idea.

pic 1 you got 3.120 on my 250 I got 3.146 on 200- 3.140
Pic 2 you got 1.029-------------------1.039...................1.040
Pic 3 you got .585..................................... .576.................. .572 But I meaursed closer to the tip of lobe and it is thinner there.
Pic 4 you got 3.898.................................. 3.910................. 3.880
Pic 5 you got 1.810 .................................. 1.810 ................. 1.785
Bottom line on 250 I think HaHa what I got on first four lobes .046-.039-.044-.046 ---200 first 3 .022-.018-.023 offset to the rear. on the 200 seams like something is off, maybe my head.
Best would be to get the lifter bore centers drawing from Ford and compare

With out a lot of grinding I do not think that the 300 lifters will work. a shorter link height connection and the lifter body cut away and only a tower like support for the link connect button, morel and Bam has some like that and not the full round upper body that the 300 ones do. Less button stick out away from lifter would also help.
Keep in mind that the 200 needs rod clearance notches that the stock 250 cams do not have. Most after market cam makers use the notched 200 cams for the 250.

Yeah. Sorry I didn't have time to run the math. I took measurements, took the kids to the park, coached some 8U baseball, and now I'm sitting at district Roundtable for Scouts! Never a dull moment around here! LoL

I also could have bumped on my way out too. I tried to be careful but you know how it is! Normally I would measure 3 times and throw out the outlier LoL

I had to do some grinding to make them fit for the 250. I actually had less of a problem getting them into the one slot that I tried on the 200. If I get time, I will attempt to grind out the end holes to make it work. It's mostly a matter of time. I'll focus on getting into the ends and take some before/after of how much I have to hog out.

First I would try to get the lifter into its bore on one of the double wide spots first. Because the 200 block lifter area is so much shorter, I think the tall roller lifters will hit the outside of the top of block a lot before it lines up with the lifter bore and slide in. If you look it the end opening they are closer to the outside edge of the block which is good. Time will tell
