RE: {Chrysler 300} Caution to all J/RamK owners or anyone using 63-64 he

Rather exotic exhaust headers on J&K ram engines are factory.

With a side tap for routing exhaust heat up to the bottoms of the aluminum ram intake just under the carbs for carb heat. Caution, a burnout of the aluminum intake may occur. Some blind off the heat pipes and others orifice them to eliminate/reduce heat for carbs.

Not difficult to imagine these exhaust headers glowing cherry red at full song. All synthetic material in the vicinity needs to be protected.

All -

With the understanding that I know virtually nothing about 300J/300K, are these headers factory or aftermarket ?

Hi George,

I think that the risk exists on any car using the cast iron exhaust headers. Due to limited length the cable must be routed between the header and one of the heat pipes, and with about 1” to 2” of clearance (i.e. NOT resting against the header or heat pipe) the heat is still sufficiently intense to melt all of the insulation over time to expose bare copper; hence, the resulting short b/w the positive cable and the solenoid wire. That will engage the starter solenoid while the engine is running.

A direct short against the header would be worse, as that would be a dead short to the battery, not cool!

I have used these cables on non-header cars without incident, as the log-style exhaust manifold is not in close proximity to the cable.
