What to do if your RV has a 454 problem?
The plug wires burn out from the heat. I was told to get a good set and replace evvery 25000 miles. I figured may I would cut holes in side panels to let the heat out. In aviation we always figured the heat outlet should be twice the inlet size. Good luck. George ▶ Reply Thank you for the comments George.
Is there a problem with my 454 engine?
I have asked a number of people and have been told that it is a motor home issue caused by the dog house engine cover and that the 454 was redesigned around that time to increase engine heat to increase millage. My question remains, is it just my 454 or have other people had the same problem?
What do you put in the boot of a 454?
The splash shields on the right side of the motor have been removed I assume in an effort to let some of the engine heat escape. I have finally found a way to keep the heat from attacking the boot. I use the heavy duty boot, place it inside of the heat sock (used on race cars and such), and fill the heat sock with silicone designed for wood stoves.
How does the fuel pump work in a 454 engine?
It pumps fuel to the throttle body and the direct fuel injector system through the fuel supply line and then through an in-line fuel filter. The pump is designed to provide pressurized fuel at 125 kPa (18psi.) A pressure regulator in the TBI keeps fuel available to the injectors at a constant pressure between 62 and 90 kpa. (9 to 13psi.)
What kind of fuel system did the 1980 Chevy 454 use?
A M4MC or EM4MC carburetor was used on most of the 1980 series engines. This is an aspirated fuel delivery system with the addition of a mixture control system controlled by the ECM.

Can a 454 be used as a diesel?
While you are correct the 454 won’t have the torque of a diesel, it sounds like Dave and Bea have a problem. We had a 91 Pace with the 454, and we could still do 45MPH over the Tehachapi pass in California–a pretty steep, long hill. Sounds to me the engine just needs a good tune-up as suggested by the other posters.
Why does my motor home stall when I Turn on the vacuum?
My motor home has a fuel-efficiency gauge (vacuum meter) and the stalling starts when I enter the yellow to red zone (low vacuum, I guess) and disappears when it is back to the green zone. ▶ Reply It sounds as if it’s the 454 curse to me.
