Fresh carnage!

In reality, the bolt with the hole works OK. We’ve got a 273 with 300,000 miles on it and still runs better than most with 10,000 miles. Built in the 70’s with the bolt with the hole and a Direct Connection double roller timing chain. Car lived from FL to SD. And from the stories was never babied, cruised at 100 mph all day long, and has been up to 140 mph. The 273 is slated to come out this winter, but only to be replaced with either a 330 Desoto hemi or a 340. I am interested to take it apart and see just what the wear looks like after 45 years and 300,000 miles.

I get it works ok. So does no holes in any bolts. Or no drip tray.

Ok isn’t good enough when I have to stand behind it.

Drilling a hole in a bolt isn’t any harder than drilling a hole in the plate.

And it’s not just for gear drives or Chrysler stuff.

I put pressurized oil on Chevy’s too. Splash oiling or relying the oil mist in the engine doesn’t get enough oil where it needs to be.

Even though the cam gear turns half of crank speed there is still centrifugal force throwing oil off the gear and chain.

Where the oil hole in the plate is sprays oil on the backside of the gear and centrifugal force is forcing the oil between the gear and the chain.

And the fuel pump eccentric and pump arm will look better.

Guys are willing to drill a hole in a bolt but not in a plate. Makes zero sense to me.
