1967 Chevrolet Corvette

427 L89 Tri Power IU 435Hp - 4spd Big Block C2 Vette 1967 Chevrolet Corvette 427 Tri Power 435hp Now Built to 600hp. Original vin stamped on the block but we has no supporting documentation or build sheet. Please read the entire description below. One of the first things people always ask is how many Corvettes were built with these options? Published GM records for the Corvette allow us to make a few assumptions and then some guesses to arrive at a number that should be accurate, but might not be, because it does require extrapolation to get and therefore presents no guarantees. I am only going to consider options I was able to document as original to the vehicle and percentages that I could validate, for this calculation. Here is what I can tell you with some certainty – 3840 production 1967 Marina Blue Corvettes were built. From this point forward you get the extrapolation based on known ECL code break downs which should hold true - but again there are no guarantees, they did hold. For example 63 percent of 1967 production was the convertible body, does that percentage hold for the Marina Blue paint choice? I personally believe it probably does, so I estimate that approximately 2420 convertibles were built in Marina Blue. Next we come to two tops (this vehicle shows evidence of being a factory two top car, however the auxiliary hard top is not available, 41 percent of the convertibles were two top. I think that percentage would also hold so our number is 1003 Marina Blue two top Corvettes. The other significant option appearing on this car is the presence of a 427 engine, it does appear to be a factory big block vehicle, that narrows the number somewhat more but still leaves us with a vague understanding of what the car actually was from the factory the new number appears as 165 big block 67 Corvettes in Marina Blue with two tops were built. The reasoning for the use of these options as choices in the above analysis will become obvious, once you complete the report review. This again does not account for the interior or seats, frankly those percentage build numbers are not identifiable. I do suspect the above extrapolation is a real possibility and it should allow us to use other options present with the vehicle such as side exhaust if they could be documented as original items to the vehicle but at this point they can't. My inspection confirms that the only options present on the vehicle which could be confirmed other than interior color and leather seats are those mentioned above and used in the analysis to break the production number down to 165. Each of those options appears to be factory restored original configuration for this vehicle and every manufacturing technique known to apply to the installation of those options is present and appears accurate for the vehicle. Additional options are present, all considered desirable and all lending the restoration to the appearance of a very nice 1967 Corvette. I would simply caution you that the engine, transmission, rear end, interior, exterior color combination, side exhaust and bolt on wheels should not be claimed as original - therefore there is no guarantee of the configuration as represented. The engine is stamped with the original vin number but we are selling the corvette with no documentation supporting its a true numbers matching car. The Trim Tag and VIN Tag affixed to your vehicle and pictured above appear to be unaltered original GM issued items that have never been off the vehicle. The Trim Tag reflects “67-467” which confirms the 1967 model year convertible body with St. Louis built body number “S2421”, my physical inspection confirmed that indeed the body is a St. Louis built body. In 1967 there were two body plants for Corvette production, one in St. Louis and one in Ionia, MI., this body number “S2421”, is a St. Louis built body and is a perfect fit in the production sequencing as it falls in line with the actual build sequence for vehicle 04431. Of significance in this paragraph is that the car carries a St. Louis built body! Simply because it is a well-documented fact that in the 1967 model year except for the first few days of production only St Louis Bodies were used in big block Corvette production. The Trim Tag in addition reflects “D22” which is a production date that translates to November 22, 1966 and corresponds with the known production time frame for sequence 04431, it also will match the GM/NCRS Shipping Data Record that would indicates a production date of November 22, 1966. In addition the Trim Tag shows “Trim 414BP.” which reflects Bright Blue Vinyl, No Power Windows, No Headrest, No Shoulder Harness, No Automatic and includes the Optional Hard Top. The “976AA Paint” reflects Marina Blue as the paint color combination with black hood stinger (this car carries a white hood stinger as restored) . The white/blue interior in the car is an owner inspired upgrade and the correct hood stinger color for that upgrade would be white as it is presented. A significant piece in the collectability of a 67 Corvette is the original engine. The engine pad and casting dates pictured above are of the engine in 04431 this engine is casting number 3904351, configured as a four bolt main 427, cast “G16” pictured above right. 04431 was built on or about November 22, 1966, this engine block cast date translates to July 1, 1966. The machine code pictured above left is “T1028IU” where “T” stands for Tonawanda assembly, “1028” stands for October 28 and “IU” represents a four bolt main 435hp RPO L89 with Aluminum heads. This pad also carries the VIN derivative of “7104431” represents the model year 1967 and vehicle sequence number 04431. Unfortunately this is a restoration engine and cannot be considered as valid proof this vehicle is a factory production L89 vehicle. The body configuration present on this car shows signs that it was indeed not a four bolt main RPO L71 or RPO L89 vehicle, that includes among other things multiple mi
