Default Help identify an engine.Is it correct for my 1964?

Looking for a correct engine for my 1964.My car was manufactured in december 1963(D5)
I came over this engine and need some help to decode it
Here is the info the seller sent me:

The only number I can find for a date stamp is "J232" That number is located on the top right rear of the block, behind the right head. The other number on the back left side of the block, that is the GM number is 3782870.

The number under the passenger side head is FA36985.

The small number is L145112. Let me know if this helps. Also, the GM number I sent over shows an earlier year manufactured
327, I believe it was 1962 - 1965.

CORRECTED
I think that is an October 62 block which puts it a year too early for your 64. "I thought yours was a 63 when I commented". I am told NCRS gives you a 4 month window. Mine is a k62 with a March build. Non original block. I am sure the real experts will chime in soon to correct or confirm.

October of 62 would be for a 63 or am I missing something? I have looked for a decent price on a late 63 block forever since mine was born on January 20th of 64. I finally rebuilt what I had.

The date code J232 indicates October 23, 1962 which is too early for your December 5, 1963 car if you're trying to stay within the four month limits for a "correct" engine. Even four months, I'm told, is stretching the limits. Six weeks or less would be the ideal. Couldn't find the head numbers in anything relating to Corvette but I could be wrong on that since my references are limited. Dave

D5 is December 5th if it's a St. Louis body, or April 5th if it's an A.O. Smith body. Is there a letter ("A" or "S") in front of the "Body" number on the trim tag?

You need a 3782870 block (from Flint, not Tonawanda) cast not more than six months prior to your car's final assembly date. A Flint block will have a single digit for the year in the casting date, and a Tonawanda block will have two digits for the year. A Flint block will also have a square-head 1/8" NPT plug just above the timing cover at about 11 o'clock - Tonawanda blocks don't have that plug.

The block casting number is close to the bell housing, and the Serial number and the suffix are stamped on top of the block surface in front of the right cylinder head.

This link should help you out===> CLICK

This is a great site with a multitude of infomation thanks to barryk.===>CLICK for Vettetech

If your engine is a 365HP, manual trans, A/C without T/I, then the suffix should be RR. If it has T/I, it should be a RU.
