I am going to look at a SBC engine for sale The casting on it is 3959352 which suggests 1964 283 The pad appears to have CFC 1207 with a 88 stamped in different font at an angle Can someone help me make sense of the pad meaning ?
I have seen these type stampings before on counter engines. You're engine wasn't installed in a car or truck at the factory, it was sold over the counter as a replacement/crate engine. Are you sure the number isn't 3959532?
how about a picture of the casting number and casting date and a picture of the whole engine? also please choose full image when posting pics...
that's not a Chevy stamp...it's from some machine shop or something.... As Mark said, the casting numbers on the back, and what other parts have been installed on the engine, will give you all the info you're gonna get on this one. Sorry.
I've seen the CFC code on early 60's 283's and 327's built at the Flint Engine Plant. The 1207 stands for December 7th. As mentioned earlier, the 88 is probably from a machine shop or the previous owner. That part of the stamp isn't from the GM engine plant.
Thank you Squirrel , as far as I am concerned ,your word ,need not go further in this conversation Tunlrat
I'm interested in Todd's reply...as there are things about the stamp that do look like Chevy could have made it. It's not the normal sequence we see on most engines, though.
I slipped over to the dark side to a 2011 thread on a Corvette board and if Old skydog's info is correct that is indeed a replacement block. There should be a date code just above the bellhousing line in line with the distributor hole or close to it. That will have a letter, day of the month and last number of the year.
A 4 digit number stamped like that is most likely an invoice number from a machine shop, so they can keep track of who's block it is.
Factory 62 283 is going to read C = Regular production engine 3 speed. CD = Regular engine overdrive D regular engine powerglide. That from the 62 Chevy pfd from the GM heritage center archives https://www.gm.com/content/dam/comp...information-kits/chevrolet/1962-Chevrolet.pdf Link to the pfds for various years Info is good from mid 30's to early 60's turns more into the sales brochures and model info later. https://www.gm.com/heritage/archive/vehicle-information-kits Dang, that will teach me to read through the whole thread before checking for an answer. I've got to agree with Jim, that number stamped on the pad by the fuel pump is a machine shops tracking number. It probably matches numbers on the work order.
It was morning and I hadn't had a full cup of coffee yet. That's my excuse and I am sticking to it. An interesting tid bit though is that according to the Lime Book 3 digit prefix/suffix numbers didn't start until 1970. That is except now, because around 1966 the third digit meant either Holley or Rochester carb on certain engines. http://www.camaros.org/pdf/LimeBook.pdf
like I said, they're most likely the invoice number from when the block was taken to a machine shop. Many shops stamped the work order number on the parts they took in, so they could keep track of them. they are NOT original Chevy numbers.
