VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1937-1945 Unusual Set of Rods

I bought a set of reconditioned rods for my spare parts shelf. They were bargain priced so I couldn't resist ! They are for a 1937 to 1947 216. They were re-manufactured by the Daniel Heil. company. The boxes are marked 002 which I would think stands for .002". So measuring across the bore near the parting line with a pair of digital calipers it looks like they could be very close to standard or .002". It comes with a shim pack installed on each side that are over 30 thousandths thick! I can peel the pack with a knife and the first layer I looked at appeared to be .001 ". So these rods would install with about .030" of shims on both sides. I am used to seeing .006" in shims to start off with. They are close to .002 under in the vertical direction with the full shim packs installed.

The rebuilder may have used a different thickness of babbitt than what Chevrolet did in 1937-1947 and made up for it with shims.
The babbitt was .005" to .010" for 1937-1947 and was reduced to .003"-.007" in 1948.The thinner babbitt compresses less and rods require less adjusting with the thin babbitt.
You will also find rods from different engines are of different weight. w Chevrolet built te engine thay chose rods of the same weight for one engine-the same with pistons. If you ever use the rods have them balanced. Also the 37-47 rods came with three different forging numbers. OK to mix as long as the weight is the same.

I am thinking that maybe they shaved the parting surfaces by that amount but didn't do a rebore. I wonder about rods that have that amount of brass in shims between the parting surfaces !

Has anyone seen that name before, Daniel Heil mfd ?
