Engine Specifications Chart

I have a 1990 345 with the 454 engine. This used the Chevrolet 1989 P30 chassis. I need the timing and idle speed specifications. In fact if the owners of the different Classic models would provide this I will make up a spec list for all of the gas engines. The info is usually on a sticker on the radiator or on the air filter cover. Airstream has no idea what these are.

Howard,
Try a search on the forum for engine timing and idle speed. Many here have discussed this already and the search feature can be your best friend for quick info like this.


Lastly, the trick on timing the 454 in a motorhome is to use cylinder number 5 and the lower timing marks (these were added because you can't see the "normal" upper timing marks in a motorhome.

On my 350 1991, the specs are on a sticker on the air filter housing. If it ever stops raining, I will report them to you.

Mine too but it sounds like Howard is missing his sticker. Pretty sure it's 8 degrees BDC and 750 +/- 50 at idle.

Missing Sticker

Yes it is missing. When I had the Banks installed many years ago they tossed out the old filter and replaced it with a K & N. So good by specs. I have been told both 4 degrees and 8 degrees. Chevrolet is no hope since they refer you to the sticker. Airstream says they no nothing about the engine.

And! The answer is-----

The original factory setting, considering emissions, was 4 degrees. The recommended setting, for best gas mileage and engine power, is 8 degrees. The idle should be 650 to 700 rpm. This is for the big block 7 plus liter engine.
