Also where are the stamping numbers on a 396 so I can identify the year and model of the engine ? Thanks Denny

L205760 L is Los Angeles built 205760 is the unit number off the line. The engine number should be stamped into the block on the head mounting surface on the passenger side at the front. It should include a suffix. There should also be a casting date at the rear of the engine near the block casting number. The cylinder heads also have date castings under the rocker covers. http://www.yearone.com/updatedsinglepages/Id_info/decoding_body_tags.htm

Also where are the stamping numbers on a 396 so I can identify the year and model of the engine ? Thanks Denny Hi Denny, Congrats on your purchase! I like the '69 Chevelle SS 396 cars,even though I do not own one :) I show the trim code 751 as a black vinyl bench seat interior. The 7B is body build date.This car was a VERY late built car for '69.Second week of July.The L205760 is the body plant sequence number.Usually by '69 this number would start at 100001,so your car was the 105759th car built at that assembly plant for that model year.The number 8 down low on the trim tag is usually an option accessory code.Does your SS have a vinyl roof? The right front engine pad just below the cylinder head should have 2 sets of numbers.One will have the last 6 of the vin,the other will have engine suffix code and build date.Check to be sure you have a 12 bolt rear end with both upper control arms and front disc brakes as this was standard on SS396.In '69 it became an RPO code option package(Z25) versus earlier SS396's which were separate models.What are the first 5 digits of your vin? Hope this helps,Jim

Thanks Denny Denny, I thought your car was an LA built car by reading your initial post here.The fact that it is a BAL built car changes the L205760 meaning.If the location of these is in the lower right of the cowl tag(below paint code)those are Fisher Body specific plant codes.Same for the number 8 you mention.Are you sure about the trim code being 751?I show that as a black cloth bench seat. Sounds like a good find! Jim

Jim, I just checked the tag again and the trim code is 755 and just below that was the 7B AND JUST BELOW THAT WAS THE 8.The vehicle was sold 07/28/69 in Virginia so it looks to be a RPO Code car and I believe the 8 is the radio delete option

Jim, what do you make of the data tag on the inner fender well drivers side? How is the weather holding in Chicago? The weather here has been ok.Just finally started getting nice over last week or so. I have never heard of or seen a cowl(trim)tag riveted to an inner fender well!Only to the firewall in this era of car.That is wild stuff if it was originally put there.I did some more digging and found your trim code 751 for black vinyl bench on base sport coupe model. I'd love to see a good pic of the cowl tag.I've seen mis- stamped 69-70 cowl tag occasionally as well.I've also noticed when comparing same 2 cars side by side,one built very early in model year vs one built very end of model year there are some noticeable differences.Definitely some odd ball original stuff on cars out there.Did you find a build sheet or body broadcast sheet? Jim

That's the million dollar info that everybody wants....the GM plant option codes.But,most plants used whatever system they wanted and didn't keep good records.No real consistancy of cowl tag RPO coding from plant to plant or region to region.In hind sight,probably a good thing for the hobby.Makes it harder to fake a car.

Wish I did, sorry. Incidentally, it lists 7029204 also for 1969 Corvette and Camaro that have the same engine as the Chevelle. Neil

Thanks Jim and I just purchased the Qudrajet that was recomended so I hope that with not starve it? Checked the heads and they are 3964291 castings correct for 69 396 but the stamping numbers on the block are gone because of decking and there is no casting numbers behind the manifold so not sure where to check, let me now on the carb. please
