Are you talking like, women’s hosiery? Could be a good idea to keep some in the glovebox for when you encounter a dusty road I suppose...

In 6 years have you experienced any real detriment to running open stacks? More frequent oil changes maybe? Any compression loss?

So, I am VERY curious about this. Back in the day folks ran chrome (chromoly) rings in dusty conditions. They’d last longer than cast rings, but would also wear the cylinders faster. My 289 has plasma moly rings that are supposedly pretty unforgiving in dirty conditions...

When you rebuild so often, are you able to “ring and bearing”, or are you finding the added abrasive in the system is wearing bores and journals too? What about valve guides? I would be very curious to take apart a motor with a couple years of use in dusty conditions just to see how much of the cautionary aspect of filtration holds true.

Have not run in any real dusty conditions. Typical rebuild/refreshing is rings, bearings, valve springs and seals. Running an aggressive cam at high rpms on a continuous basis is tough on the springs, bearings and rings.

Jeff i right in that if you have an original style transverse leaf spring suspension, there is not a lot of clearance to the hood from the horns.
