Herm,they look nice.I have several 28 Chevy engines,but at least one of mine has, like 1/4 inch spacers between the rod body and cap. I don't see that here?? Guess if I'd look closer I could see these are the main bearings.I think some of mine are on bronze inserts.
Nice pictures Herm. I may get run off the forum but it appears Chevy had a better idea than the better idea people when it came to thrust bearings. Even if a guy doesn't like the center arrangement, the 360 degree bearing surface would have done Ford well to copy. Nice work!
I have thought that any T blocks I have done in the future will have full 360 thrust on the rear, also put babbitt locking holes along the part line like Tom does for the Model A blocks.
Herm, You do beautiful work. Almost make me want a chebbie motor. At least the crank and your work. Scott
Jack, the rods are the only ones that takes the spacers. The mains, on 4 cylinders have .006 brass shims on either side.
The rod metal spacers are .101 thousandths thick, with a .006 thousandths shim added to that.
I have the rods to do yet, but we are looking for more rods of a certain weight to make a set, so they can balance the set. When I get them done, I will put on the pictures here.
Mark, extra Anchor holes is a waste of time.
The ones that are in there already, are plenty.All the anchor holes do is keep the babbitt from turning.
What keeps the babbitt in, is a good peening job, Only.
You could make the block look like swiss cheese, and the babbitt would still break up, with out proper Peening.
Beautiful work...I have seen a 28 chevy block mounted on a model T pan utilizing the T transmission and hogs head. For those of us that like something different....it was a neat set up. As I remember, it was very smooth and performed well. Chevy has oil pressure to the main bearings and a strong crankshaft.
I have modified a 28 chevy crankshaft to fit in a T block which was a modification that was performed many times in the past. It requires about the same amount of work as installing a model A crankshaft.
Today, buying a Scat crankshaft is a much easier way to go.
Herm, you do great work and I have a lot of respect for the knowledge you share with us.
A very nice job Herm,
but not that it matters and no way reflects on your work, but we must call a 'spade a spade' that's not a 28 block. 26/27
