Technical sbc engine identification

i have a chance to get a 62 to 65 327 engine with the 194 double hump heads on it. I have checked the casting numbers, but I am having a hard time disecting the serial numbers on the front pad. Any help is appreciated. thanks
numbers are 5D128763

 

How about the casting #'s on the heads?????

 

is there another series of numbers/letters stamped on the block? that looks like most of a partial VIN...from the 1970s, possibly.

we expect to see something like F0514CMD

 

I don't have the head casting #'s yet the casting number on the block is 3782870

 

then it's a 60s 327 block.

No other numbers stamped in it?

 

It's in my neighbors trailor, I will have to check later. He does own a 62 corvette that the engine was part of the deal when he bought it.

 

Corvettes were mostly the only Chevys that had a partial VIN stamped on the block in the 60s.

 

I might ask to check the vin on his vette. It might be the original 327 from it.

 

Well, if it is, you'll be blessed to have one of the few "327 Vette" engines that actually is!!

Last 3 digits of the heads should be 461 for '62. 61-63 there was a 461x head that had large 170cc intake runners. The x will be cast on the underside...

 

I haven't check out the head numbers, but I did get the rest of the stamped numbers which are F0107HB and the first part of the stamped numbers are #5d128763

 

HB is a manual trans 300 hp 327 from a 65 full size car...sorry, not a vette motor after all.

 

Back in the mid/late '60s I worked in a Chevy/Buick dealership. The 300hp 327 was my favorite SBC. Still would be for carbureted traditional engines....it was smooth and pulled very well.

Yep, I had a 300 horse 327 in my 64 Corvette. Damn fine engine.

All are from vettes. Unless I buy it

 

I checked out a few other numbers on the engine and some of the components.
Valve covers are original 7 fin corvette, marked Lester 3767493
Heads are 461 no x marking 160 intake and 62 exhaust matching

It turns over freely and the valves look to be doing the correct movement.
I don't care if corvette or not it's still a fine vintage engine.


Thanks for all your help guys.

 

if you find the casting dates on the heads and block, you can get a little more info about the engine.

Look for letter/number sequences like A 3 5, or similar. First letter is the month (A=Jan, B=Feb, etc), second is the day of the month, third is the last digit of the year (5=1965 or 1955 or 1975)

 

I did find the date code it's A 5 5 on the engine

 

my guess was off by two days

the heads will have date codes too, see if they are close to the block, if so they're probably original to it. If not, they are not.
