One of the peculiar things about 2600 SZ engines, which I consider almost a fact based on statistical evidence of data I personally collected, is that the engine number range starts at 10000 -- a range that according to Fusi and other sources does not exist (and I have yet to come across a 00612 engine as listed in Fusi). I consider any correlation between engine and chassis number on 2600 SZ cars a pure coincidence, but I do know of one or two such matches. BTW: So far, I have found absolutely zero indication that there is ANY difference in performance between 2600 SZ and Sprint/Spider engines. The only differences I know of are (a) the engine mounts having a different angle (because of smaller rubber supports) and (b) an unconfirmed difference in the oil pump using a narrower adapter for the hoses to the oil cooler -- both of which are concerning clearance issues inside the 2600 SZ engine compartment and not performance.
