Dodge timing chain, nylon cam gear issue 3 Replies

Heads up to all you Dodge V8 owners. My 1973 360 timing chain fell off the cam gear just south of Toledo in October returning from New York.  Needless to say, we were stuck on the side of the road.…Continue

Chris,

Yes, 441 is 4 lanes most of the way, no traffic. Some small towns, takes a while, but few semis, very relaxing. Many campgrounds are close to 441. Picking it up in Athens, GA, going directly to Gainesville, FL, then down to Ocala, over to 95, then US1 on down.

Jack,

Of course, you're correct, exhaust valve. Seat is recessed. Going to have the head rebuilt with hardened seats.

Has an Endlebrock Torker manifold and Holley 4150 that I inherited from the previous owner. Torker is a really simple large plenum manifold. Maybe I should find another manifold or a factory 4 bbl manifold. Cast iron is ok. It is an RV, reliability is important. With TBI the lean condition would still exist at the 1,2,5,8 cylinders.as the manifold would be the same. Port injection would be better. Not sure this is all worth the expense for an RV. I could just be sure the end cylinders are rich enough. EGT would work, used on  aircraft, or I could fit a wideband O2 sensor near the #8 cylinder.

Jack Wasmuth, my bad. I didnt mean a test gauge I meant a dash mounted. I was factory trained on Sun Engine Analyzer and Dynanometer.

The true sweet spot 22 psi (secondaries open). The vacuum decreases from 27 psi on acceleration, causing the timing advance to actuate at approximately 65% of torque output and the carb accelerator pump squirts . Yes atmospheric pressure does impact performance. So what happened with the burnt valve, I agree burned to lean. LOL I was typing when your reply came in.

All the tricks and tips we did, are now done on chips.

A vacuum gauge is a good tool for finding the sweet spot for timing if you do not have a timing light and also for adjusting the idle circuit on a carb. However a vehicle does not travel down the road at idle. Fuel mixture and timing change with rpm and load. 

I had a chassis dyno in my repair shop and it is a valuable tool to properly tune any vehicle as I could see what was happening while pulling a hill with a load. A adjustable timing light and the ability to read a spark plug is crucial. A carb will go rich while climbing in altitude. It is necessary to jet the carb leaner by 0.002 for every 4,000 ft rise in elevation. Hope this helps.

I second that, Postman! A GOOD vacuum gauge and a REALLY GOOD Timing Gun!

Jack Wasmuth  I have a 440-3, carter on an edelbrock performer (sealed the deal), because wont run worth a darn without the right cam.  Somewhere i read a conversation about vacumn and rich and lean. I reply, "A vacumn gauge is your best friend on a dodge big block."

Hmmm. Must have gone on the wrong thread... Also, the celeryfone is actin' up.

441 is a back road heading North South
Comment by Jack Wasmuth on May 3, 2018 at 5:18pm

Dave your problem was more likely caused by a lean condition. The four corners cylinders of a v-8 tend to run lean and the #8 cylinder is the most common. Unleaded fuel played hell with the valve seats. Is your seat recessed? I can't tell buy the picture but that is a exhaust valve, larger is intake. 

I installed a TBI unit from Affordable Fuel Injection. It is a complete early 1990's Chevy 350 from a pickup. The reason I installed this unit is ease of install and the availability of replacement parts and coast. Just less that $1,000.00 (I did not use their Dist.)
