Default Engine Date

Looking a t a possible # matching 65 I saw that the date on the engine was J and dated for 1965. Where engines date that late in the year and still put in 65s?

On a side note, anybody in the NC area REALLY know their vettes and/or a website that gives great detain on numbers and what not?

Thx..

Mike

At a minimum check the casting number on the block and make sure that it preceeds the assembly tag date under the dash. In addition, I would check the tranny and rear axle dates.

Default Casting number identification

I have found two web sites that provide good information on identifing the transmission / engine block / heads / intake, etc. that may be of some use.

http://www.nastyz28.com

http://www.corvette.net/tech-5.htm



Once you are in the front page of both these sites, you should be able to dig in deep and find the useful information.

If anyone knows how I can de code my bell housing, please let me know. I am fortunate that my car has the VIN number stamped on the transmission and I would like to identify what year is the bell housing. It maybe that there was so many part numbers that there is no firm set written identification of the various casting numbers.

Good luck

If it is a really a "J" engine casting date code for 65 (like J125, for example) that would equate to a block cast in October (J=Oct, the example would be Oct 12, 1965) and such a block would not be appropriate for the 1965 model year, they built the last two 65s in August of 65, but even those likely have a block cast in July.

Personally, this is why I think a look at the block casting date is one of the best ways to smoke out a restamp; pretty tough to get a perfectly-dated block that won't raise red flags when compared to the engine assembly date and "birthday". They do fake casting dates too, but I think such is reserved for trully high dollar engines (certain BBs)

I would purchase a Corvette Specification Guide from the NCRS . Best $12 spent when looking for numbers and dates.
