Will a 1994 v6 Camaro transmission fit Chevy 350?

No, a 1994 V6 Camaro transmission will not directly fit a Chevy 350 small-block engine. The bellhousing bolt pattern is different. The V6 Camaro used a different transmission (likely a 4L60E, but possibly others depending on trim level) than what's typically used with a 350 (like a TH350, TH400, 700R4, or 4L60E - *but even if both are 4L60E, there are differences*). Even if you found a 4L60E from both, the flexplate and bellhousing would be incompatible. You'd need an adapter or a completely different transmission designed for the 350.
