New guy here looking for engine code help
Hey everyone 
New here, just been surfing thru the posts for a few days. So I have this 64 and I know that the engine isn't original. Doesn't matter to me, I am fine with that, most of the car isn't original, button tuft leather interior, Doug Nash 5 speed, 67 hood.
I am wondering what the engine is. From a little research I believe it is a 65-67 327 from a Chevelle?? I'm hoping somebody here can shed some more insight
Here's the stamp on the driverside rear of the engine 3782870
Stamp on the front passenger side is F0520EC
Engine's not stock either I'm sure, heads have larger valves, ported, polished
Thanks to anyone!!
Shawn

Wow, you guys help out quick here! 138007 is the other number on the front passenger side of the block. If I'm right that number has to do with the VIN of the car it came out of??
So I either have a Chevelle "65" 327/300 or 350hp or a "66" 327/275hp
What's the 'special high performance' refer to??
Thanks for helping guys

I'm fairly sure GM stopped using the 3782870 casting with the end 1965 model year. If that not the case I have some reference manuals with misprints.
The block casting date on the rear of the engine will lock down the model year. The casting date is a letter and number code found right of and below the distributor on the surface above where the bellhousing bolts. It will be a single letter followed by a series of numbers. The letter is the month. "A" being January through "L" being December. The number represent the day of the month and the year. Flint blocks will use the last number of the year (1965 will be 5) A Tonowanda blocks will use the last 2 number for the year (1965 will be 65).
Hope this is some additional help.

The leading number on the block should be something like 5K118701 F1215EC. The 5118701= 5=1965, K= Kansas City, 118701= sequence of car.
So, this example is a 65 Chevelle, with the L-79 engine, manual trans, built in the Kansas City plant.
They made only 6021 cars out of 199,000 plus cars with this engine, in all models. See http://macswebs.com/l79registry/index.htm for more detail.
I should have never sold my car. 65 SS, L-79, 4 SP, Tach in dash, padded dash, 3:31 posh, radio, white with blue bucket seat. Bought it thru Yenko Chevrolet, and drove it to California twice and back again. Sold it in 1968 when my first daughter was born so we could get a station wagon.

Wow, so it is the 350hp engine. I know the heads were fitted with oversied valves, ported/polished and she ran like a sonofabitch. Hopefully I can get her running with a little massaging. Been quite a few years since she's ran. Marvel Mystery Oil and some hand cranking this weekend.
Keeping my fingers crossed
Thanks for all the help guys!!!

And yes the heads should be 3782461 castings with the double hump symbol on front and rear. They came in 1.72 intake valve size for the 300hp engine and 2.02 intake valve for the 350hp, 365 and 375 fuel injection engines.

See if you can read ''all'' the numbers on the front pad. Then we can run a trace on the car. It would be real exciting for a 65 Chevelle owner to discover his ORIGINAL L-79 engine was still out there just waiting to be reunited.

The numbers on the rear are 3782870.

The 138007 is the last digits of the vin number. The beginning of the vin number will tell what type of model the car was in, like a Malibu, or Super Sport coupe. The assembly plant LETTER was also included in the vin.
A typical 1965 U.S. built Chevelle VIN might read: 138375Z108031 being a Malibu SS V8 2-door sport coupe assembled in Fremont, CA.
see for more detail explanation

All fun stuff, but off CORVETTE topic. PM me if you want more.
