Stuey: The originals had to have been stamped. Hand building them like you are proposing would have been too slow and expensive. Even Ford must have thought stamped ones were too expensive and eliminated them. Thousands of new car buyers never new the difference. The use of tool steel would be overkill, they are clamped in place, there would be no load on the key. Are you thinking of producing them for sale? It would be a very small market. JMHO

here's wishing everybody a happy and prosperous new year i'm just back from the kids carrying an extra 7lbs weight thats not good it takes months to shift.. Ted thanks a bundle for the counter wt. pics they scaled up good. can't come up with any thing 160 thou with out surface grinding but 4 mm is only 2 thou shy and its off the shelf gonna use grade 01 tool steel its a bit better than mild steel and i'm thinking it will be better for the keyway now there's another problem. i think the key way is 5/32 and the bore is 1". the only broaches i've seen are 5/32 B and the only sleeves of 1" do not go down to 5/32 any comments advice?? thanks folks stuey

.....any chance of a similar pic of the counter balance? MerrY Xmas and a happY New Year to all Y-blockers, stuey Here’s a pic of the fuel pump lobe counterweights against some machinist rules. The counterweights are about 0.160” thick.

........ any chance of posting a flat on pic. I'm guessing its the same thickness as the spacer an could scale the pic from the bore to come close? Stuey, here’s a pic of a couple of the oil troughs next to a ruler.

Ted i see you've had no offers, i've been looking ever since reading your article on camshaft balancing and have not come up with anything. i think i could bash up a trough with a big hammer and a piece of rusty tin but the counter wt. would need some help. i'm guessing you are going to be more successful than me in obtaining one, any chance of posting a flat on pic. i'm guessing its the same thickness as the spacer an could scale the pic from the bore to come close? thanks in advance stuey

Ted: Early inline chev sixes had a short tube extending over the timing gears, connected to the camshaft bearing oil passage. Could this idea help a Y? I think Speedpro's engines have a small (.030?) hole drilled into the front oil passage to squirt lube onto the crank gear. Richard Gaston used to scratch a small notch in the front cam bearing to bleed extra oil to the cam thrust area. I have seen several engines with wear in that area.

Ted: I'm intrigued. Are you finding the timing chains need a little more oil? Or maybe trying to control windage at the front?I’ll say Yes on the need for more oil. Those engines without the oil troughs do appear to be more heavily worn on the timing gears where the links on the chain are digging in. This is just a random observation as I don’t have a clue as to the mileage on the core engines I’m tearing down but the chains on non-oil troughed engines do appear to have more slack in them than the chains on engines with the oil troughs. The additional slack looks to be primarily due to the wear in the gears more than stretch in the chains. So with that in mind, I just feel more comfortable with the oil troughs in place when I can put them on as these troughs help to better direct any oil that's present directly onto the lower timing gear which is then carried back up the chain.

Ted. Do you believe that the fuel pump counter weights are beneficial in camshaft balancing?A definite Yes when the counterweight is used in conjuction with the fuel pump lobe. How much benefit this has on the overall life of the engine is debatable though. The original engineering for the Y saw fit to include the fuel pump counterweights, timing chain oil troughs, and rocker arm baffles on the pre ’56 engines but I’ll speculate that the removal of these items in 1956 were the result of the push to increase assembly line production as well as cost cutting measures.Ford did bring the fuel pump counterweight back into production on the 271HP 289’s though so the engineers did recognize some benefit from the use of it in a performance application.
