Ignition timing specs for a 1986 Chevy 454?

You need the details of the engine and chassis that they RV is built on. Normally something like a Ford F-350. Once you know that, you can search for parts and diagrams. Looks like a Chevy 454 P chassis. Then it depends on what hoses? A properly crafted search query can find most things.

You have a 1986 454 engine with an old style breaker point ignition distributor, GM has not used a breaker point ignition for their V-8 engines since 1974, is that an older distributor or something after-market?

The ignition points dwell angle for that engine should be set at 29-31 degrees dwell (a dwell meter would be the most accurate way to set the ignition points), or a .019 in. point gap.

The spark plug gap for that engine would be .035 in. and the timing should be set at 10 degrees before top dead center.

Is this carb?Or throttle body injected?If it is carb,then the fuel filter may be in backwards,the hole in the filter points outward toward the fuel line,you most likely crushed the filter.

Diagram from air cleaner sticker is actually pretty decent.

just put a new starter in my 1993 chevy 454 and now i'm not getting fire, the old starter solenoid was sticking and melted the neg battery cable. I'm wondering if that also burned something else out?

the suburban engine compartrment allows for avery large V8s to be installed within its interior and yes any 454 will fit

The haynes manuals have pretty good wiring diagrams in them. You can get them at any parts places.

Did you check your timing? You may have the timing to advanced to compensate for the clogged filter, change your timing and then see if it will idle.
