Well, it depends on what model year you have. At a minimum, you'll have the 5.4 litre 330 CUID SOHC V8, and you might have up to a 460 CUID big block V8 or 413 CUID V10, again depending on the model year. As far as diesels go, it again depends on the model year. There was the 6.7 litre Ford diesel, then the 6.0 and 7.3 litre Navistar diesels (marketed as the Ford Powerstroke) became available, then those ceased production, and were replaced with the 6.4 litre Navistar/Powerstroke.
That would most likely come with a Rochester Quadrajet.
That depends on how well it's cared for.
either 10W30 or 10W40.
350 engine,transmission weighs about 560 lbs.
that would be the casting number of a Chevy 350
Also I forgot to mention this is a motorhome if that changes anything and it has a generator.
a Chevy 350 bored .060 over would be 360.4 cubic inches
Probably not.
That would be the 350 or the 454
That would depend on the pressure huh?
It requires an engine scanner to set the timing on that year engine.
it depends on the motorhome. class A stripped chassis and cutaways often relocate. Call the manufacturer. I did on my 1990 fleetwood and they sent me all the drawwings for free. (try looking around the steering column.)
