It all depends on the engine you have and the rear end gearing. As one of Chevy's most popular platforms in 1967, the Chevelle, especially the Malibu series, came in a variety of engine, carburetor, and drive train formats and combinations. All of which must be considered before an accurate answer can be given. See the link below to narrow down factory specs. Hint: know your VIN and car history--aftermarket changes will affect performance.

the 138 code is part of the VIN. It is the first three numbers of the VIN number. One example of what it would look like is 138377k144235. This VIN would code out as a 1967 Chevelle SS396 2 door coupe. 13837 defines the GM division, model, and body style. The K is the factory code, in this case, the Leed's plant in Kansas City, Missouri. The last six numbers are the sequential production numbers, the first 1967 Chevelle would start at 100001 and go from there. 13867 would be a SS396 two door convertible. The 138 VIN code only applies to '66-'69 super sport Chevelles because the SS396 was it's own model for those years. All other years, it was an option for the Malibu trim package, which makes identifying a true SS nearly impossible with the VIN alone because for example, in 1970 a V8 Malibu with a 307 has the same VIN code as an LS6 super sport does: 136.
