I replaced the engine A.C. compressor and dryer in my 1994 29' Brave and my mechanic doesn't know how much freon it takes. He says that he needs to know before he can charge the system. It has a GM 454 and if anyone has access to that info I would appreciate it?

While I suppose that is the best way, he can simply charge and watch his gauges until the pressure reads right. That's the way the after market "freon" charge kits work and it does fine. Seems like he ought to know that...
The engine make/model doesn't determine the a/c system size. That depends on the a/c system that Winnebago installed when they built the coach, probably an Evans Tempcon a/c system. Maybe Winnie can give you the specs, if your guy can't live without them.

I'd question your mechanics ability in AC work. Other than estimating how much to buy, I've never heard of using any means except monitoring pressure to determine when a full charge is reached. Also, be sure he pulls a vacuum before charging the system since its been opened.

My 2004 Brave had a sticker that said AC hold 32 ounces

The most accurate method of charging an A.C. system is by weight, if you know it. Then, pressures and temps. Beau (A.C. contractor for 30 years)
