I'm about due to replace my spark plug wires, What would you consider the optimum wires for a 454. I'm not looking to break the bank but am looking for a good quality wire.

Not breaking the bank and good quality often are at odds with each other. I'd shop for good high temperature wires that have a lifetime warranty. Many brands are available that meet those requirements. I mostly drive diesels, so I can't really recommend any brand names.

Napa has a brand called Beldin, lifetime guarantee. I think they were 55.00 for mine, I use them on both of our cars as well. No need to pay 100.00 for a set of wires, you're not looking to juice up super coils and high performance distributors

Beldin would be it and make sure to get dieelectric grease for them.

I would consider a set of high performance wires with ceramic boots. This helps to eliminate the heat problem with the boots. The Beldin wires did not hold up real good when I tried them, they are not hi temperature. They work good on a regular vehicle, but not on a MH chassis.

thats strange, dont know why a motorhome chassis would be any different. I used the metal sleeves that originally on my mh, also used them on my car with headers

A gas RV works very hard and the RV manufacturers often don't take in to account air flow and build for best cooling. The engine is usually enclosed at the back end by a 'dog house' engine cover that is kept low and small for inside living space. If you want a cool engine, build a bigger engine enclosure and provide adequate air flow. That's why a motorhome is different than a car, besides, you can't sleep, cook, shower and poop in your car!

Deano56,
the motor is working a lot harder in a MH because of the weight difference and the wind resistance. This generate a lot more heat, the exhaust manifolds will actually glow red after a couple hundred miles. And as BFlinn181 says, the airflow to get rid of that heat isn't the best.

if the metal shields are shot, Advance Auto Parts sells a sock that goes over the end of the wire that provides a pretty good heat shield. I've been using the socks for the last seven years, and they have not failed.
