I assume you meant 660 not 550 as the 550 is much newer, fuel injected and a very different beast. In the case of 660, some parts, perhaps. Many engine parts, no... If I recall, the Grizzly 660 is a single carb 4 valve machine, the Raptor 660 is dual carb 5 valve. Top ends are completely different.
If I also recall correctly, some tranny parts ARE interchangeable.
You can use the part selector at one of the online parts stores to figure out compatibility - look up same part for both the Grizzly and Raptor and compare part numbers.
