1972 Barth..trying to help my son and his girlfriend. They bought a 25ft 1972 Barth last year. They overheated the engine in Tucson and took it to a "shade tree" mechanic for repairs. This guy didn't know how/couldn't remove the engine, so he "rebuilt" the engine in the RV..it clangs and rattles as bad as it did before..now they have been "told" that the Barth had a "special engine" and can't be replaced with anything other than a $2500 Barth engine..I don't know Barths, I have a SOB, but they sure could use some help trying to find a rebuilt engine and someone in the Tucson area to install same...any info/help would be appreciated by a young couple having lots of problems..Thanks< Joe

Is it a class A of C?

The "special engine" doesn't sound right.

I have the brochure. It is a 454 CID.If it were a 19 foot it would be a 350. Yep it's 454
