Block casting # 3782870
Stamp pad: f09T7EF
Date casting: I 15 4

Head casting # 3782461 (2.02 intakes)
Date: D 7 4 / D 1 4

Any info.??
 
Could be...

EF is correct for a 65 325/300 (Powerglide) L74 - High Perf/A.F.B. carb.

F09T7EF - Is it possible the "T" is a "1"? That'd make it a Flint engine, Sept 17 which would match the I (Sept) 15, 196(4) for a 65 model engine.

Block casting: 3782870 is good for 62-67 327 2-bolt main.

Head casting shows: 64-66...327......Camel hump,no accessory holes,160/62cc port volumes,62cc chamber and dates of April (D) 7 and April 1, 1964.

Reference: Mortec

Certainly, they would'nt have put heads dated as April on a block dated as September, would they?
I'm just not sure of their practices back then. But today I can personally attest that their priority towards run numbers (date codes) are drastically low on the priorty list. As matter of fact, we're still dating parts at the plant I work in in 2002 format, where quality and production are taking the pre-eminence. With as competitive as the market is with foriegn makes, more emphesis has been put on quality and production rather than stopping production to change a date. In my own department we have seven presses with over seventy die sets being ran each week, and we have one more press scheduled to begin production this year with another seventy die sets to come into the plant this year. I'm not so sure that dates today reflect correctness or originality; hearing stories and seeing practices still in effect to this day. My dad retired from G.M. with 35 years of service 5 years ago and I hear the same thing from him as I myself see now: The production worker would want to stop production to get these things corrected (and to go get a coffee) but management would have no interuption of production aside from either safety or quality issues. From our own management matrix: Quality parts safely produced according to 'just-in-time delivery' management schemes = a satisfied customer and security of future workforce.
That's how it is now, but not so sure that's how it was then, in '68-69. Not to much competition from foriegn makes back then...it was either G.M., Ford, Chrysler, or A.M.C.

Just speculation on my part here.

Since the block and head casting numbers span a number of years I can see where it could happen. Since the block could be used in any 327 application but the heads were a hi-po item, there may have been more heads cast at a particular time than sales called for and didn't get used for a few months. I agree that April to September does seem like a long time for heads to sit on the shelf but stranger things have happened.

Could also be the engine was rebuilt as some point and the same type of heads were used but they happen to be on the machine shop shelf, already done, and those put back on the engine.

At least the block isn't dated in 63 and the heads in 65.

How much would you say the short block and matching heads are worth. They have about 300 miles on them.
 
First of all, there were no "I" casting date months. "I" looked too much like "1" so they skipped that digit. It's probably an "L" which would make it November 1964 not September 1964.

There's no reason the date span couldn't be that far apart but it's less likely. The block casting date would place it in a '65 model.

The 461 head castings were NOT typically 2.02 valves. In fact, when used on the 300hp engine they would have ben 1.94's. The 2.02 was unique to the L79 in 1965. The casting is the same, the 2.02 heads simply received different (and additional) machining. Of course ANY 1.94 valve 461 head can easily be made into a 2.02 valve head and there is no way to tell the difference if the machining is done properly.

Dale is correct, the EF codes out to 327/300hp with a Powerglide.

No idea on the value. It'd be worth a lot more in the car it came with than without. But if someone wants to build a non-numbers matching car with date correct parts it could be of some value to them. A lot depends on how complete it is and then finding the right buyer. A lot also depends on how modified it is and what the buyer is really after.

Short of all the details, I wouldn't expect it to be worth more than the average rebuild small block.

Dale and Rich,
Thanks for all of the good info. I think I'll either just look around for a roller to put this engine into and sell it or sit on it for a'while. I've seen people out there who would like to trade their big block parts for small block parts. Thanks again...
