Thread: SBC Identification Numbers Decifer Help

Tweet

yup, and thats why im having so much trouble with this motor, the block date code is not where it is supposed to be, in fact the only stampings on the rear bellhousing section is the cast number and then next to that behind the distributor on the flat portion is the letter K and also a number 2, those two are not stamped together, the VIN is really stumping me but the vin code is either : 1SB167145, 16B467145 or 1SB467145, the "S" and "1" are really hard to make out, as far as the suffix code?? the ones that are clear are KI1 04 C, if anything was stamped after the C, i doubt it since there is nothing that would indicate that to me, i did spray black paint into the pad and slowly wiped away trying to enhance the letter/numbers. but with the block cast number being at minimum 1968(327) the C suffix isnt making any sense to me since the letter C by itself is 1957 265/283 CID engine, and the KI1 is impala/and some chevelle applications?? with the date codes on the side of the engine with the saginaw clock its making it even more difficult to try and nail this thing down since 1. the casting number ranges from 1968-1979, the suffix code shows as a 1957, and yes the date stamp on the side of the block is undetermined given the date doesnt exist. The last is the obvious possibility that the heads are from another motor since the motor is not all original given its edelbrock intake so im sure it is a mix match motor, but solving or rather resolving what the motor is exactly would be great before i go dumping into a car to sell. just in case the motor is worth more to someone restoring a specific car or truck. but i really do appreciate the help so far in trying to figure this out. i will attempt to see if there is any other casting marks on the motor itself but so far ive seen nothing where there should be markings

By the way, to answer your question about the engine being "worth more to someone restoring a specific car", the unfortunate answer is that this combination is about as undesirable as it gets.....not a 55 265 block (restorer desirable) nor a 327 block and the heads are only good to melt to make sewer pipe (cast iron). Which they do melt them in Tyler Texas to make pipe. Sorry.
