Hello all, there seems to be some confusion about engine ID# locations, and I think I know why. As we all should know, there are two 383 engines - one is a raised (RB) block, and the other is the more common lo-block. It looks like BOTH versions were offered in 1961 - the 4bbl's were RB's, and the 2bbl's were not. The 383 RB has it's ID #'s in the same place as all other RB's, under the compressor if A/C equipped. All the lo-blocks are on a pad below the distributor. Hope this may clear up some of the confusion. Thanks, DaveG. |
