gmc7000/1984

Question:

Hi, I have bought an old gmc 7000 truck,   But I can’t figure out the transmission type, it says AW on it. Also not sure about the engine, a 366?  Anyone knwo how I can tell ?  The engine 8th didgit is a B,  I have searched everywhere for the info.  I need a carb for it. Hank

Response:

Should be a Rochester carb.  You might do better to get the number off the crab tag and go by that if you can’t determne which engine it si.  BTW the 366 is a disaster, so much so that GM replaced them with a 427 as a service replacement when needed. — "Opportunities are spawned from crisis"
