Found a couple of AFB carbs in a box I haven;t opened in a while,,,wondering if anyone can tell me what they are?? One has 38265 A5 stamped into the front bottom corner!! The other has 3921S O5. Any help would be appreciated!!! Thanks
I was thinking that the 3921 was a carb that was in a pile of stuff I got with a 401 I had bought,,but wasnt 100% sure!!! Is the 3921 a decent unit,,,there is a newer style carter/edelbrock deal on the engine now,,,would rebuilding the original be a better idea??? I also "think" that the other carb is off of a 300ci,,,,also not 100% on that either!!!!
The other carb is a 3826S and is from a 300 probably. See http://www.buicks.net/shop/reference/carburetor_numbers.shtml
