Engine, Transmission, Rearend, & Exhaust / Re: Oil Preference Feedback:
Last post by John_Kunkel - October 28, 2025, 01:08:41 PMQuote from: Kern Dog on October 27, 2025, 02:25:01 PMI have yet to gear (sic) a compelling reason for the continued use of high zinc oils after switching to a roller cam.QuoteYou don't hear much on the subject unless it relates to camshaft/lifters but look at all the other components in an engine that are metal-to-metal like the roller bearings inside the lifters/rockers, the pushrod interface, the intermediate gear/cam interface, timing chain, etc. These are all high-pressure loads that benefit from high-pressure additives.
There might not be a critical NEED for ZDDP on those components but they will BENEFIT from it...ditto for synthetics.

Engine, Transmission, Rearend, & Exhaust / Re: Oil Preference Feedback:
Last post by Kern Dog - October 27, 2025, 02:25:01 PMI have yet to hear a compelling reason for the continued use of high zinc oils after switching to a roller cam.
If one has moly coated rings and standard rod and main bearings, how are our classic engines so different from modern engines to need the zinc?
When I bought the roller cam stuff to make the swap in my 440/495, (Still to come, I've been slow to jump in) Dwayne Porter advised me to keep using the "Driven" oil.
Now, I know that using it won't hurt anything but I wonder why it is still necessary.

Only "alleviates concern" about the cam lobe/lifter interface. Look at all the other metal-to-metal interfaces in an engine with no bearing material.

Interior / Re: REAR shoulder belts, 3 poi...
Last post by Kern Dog - October 26, 2025, 10:57:06 PMI welded a 7/16" bolt in from the back side so it serves as a stud....
The retractor is secured with a washer and Nylock nut.
The upper left end of the belt will attach to the floor where the small lap belt retractor normally goes. The retractor now will be in the trunk and the lach will attach to the floor mounted receiver.
I know, these don't look stock with the red colored release button but hey...
These will look like a factory effort except for the red buttons. I'm okay with that.

Last post by Kern Dog - October 26, 2025, 10:52:06 PMI almost fell into the trap that happens when communication is not fully understood. This probably happens in manufacturing where a vendor is tasked with making something based on a set of schematics and prints. The part is made and when it is ready to be installed, it is discovered that someone screwed up.
Rich bought a set of late model Chrysler 300/Dodge Charger rear seat belts. I got measurements from him and set about to make brackets. I did not have the retractors or belts in front of me until today.
I was under the impression that the belts were wound this way:
This puts the belt going vertical right below the slots in the package tray But I was wrong. When mounted, the belt is wound on the other side like so:
This puts the belt at an angle....
That might actually be better though.
