Tory Johnson, GMA Workplace Contributor, discusses work-from-home jobs, such as JustAnswer in which verified Experts answer people’s questions. I was having a terrible problem with the wheel bearings on my 98 Chevy Cavalier and I suspect that using this website saved me plenty of time and money.
Back in September I wrote about how documentation was the must-have option when buying a classic Corvette. A series of codes and stamps are located on the engine block that will allow you to identify it as being manufactured specifically for a Corvette. The casting number is a sequence consisting of raised numbers that was cast into the engine block when it was made. Hi, I have a small block motor that a friend says is a Corvette motor because it has the spark plug wire holders on the side. I looked up the casting number and 3731548 is a 283 ci engine block used in Corvette and passenger trucks in 1957.

It is nice to know that this service is here for people like myself, who need answers fast and are not sure who to consult. I liked that I could ask additional questions and get answered in a very short turn around. Not only did you answer my questions, you even took it a step further with replying with more pertinent information I needed to know. That article focused on mostly the paper trail: dealer invoices, build sheets and tank stickers. There are dates of manufacture and the engine’s original application if you just know where to look. What’s a bit tricky here is that casting numbers on Corvette blocks can also be found on other engine blocks made by GM. In 1955-56, it was simply a continuous serial number, but one that didn’t match the serial number of the Corvette. That’s what will tell us what the original application of the engine was in terms of HP, Transmission and AC. I cannot see your vehicle so please be detailed.GM Tech (Cam) : Do you have a rough idea of the year it is? It was then followed with F for Flint, where the Corvette engine was manufactured and then the year (F55 or F56).


In 1965 it is said that there was a shortage of 327 blocks from the Flint plant, so Chevrolet used some engine blocks from Tonawanda. I’ve often wondered how many months one could go backwards when hunting down parts but I generally feel no more than 30 days and maybe a little less or more depending on the part.
Those engines would have a T instead of F on the stamp, as well as the full year in the cast date.
Unfortunately, as Corvette values rise, so do your chances of buying a Corvette with altered numbers being passed off as an original.
As my favorite mantra goes when purchasing a Corvette, knowledge is power, and the more you can learn about documenting a Corvette prior to purchase, the less likely you will get burned with buying a Corvette of questionable lineage. If the block contains two digits for the year, then it was a block manufactured at the Tonawanda engine plant and therefore is not a Corvette block (Corvette engines were almost exclusively built in Flint, Michigan). Cast dates on small block V8’s can be found on the passenger side of flange where the block is connected to the bellhousing.
On 1965-67 big blocks, the cast date is located on the passenger side of the block where the starter is attached.
The second stamp decodes F for the Flint Plant, May 18 is the engine assembly date and the HE suffix code stands for a 327 ci 300 hp with a manual transmission.
