What motor is this?

Can anyone tell me what I have from these numbers? They are the only ones I can find right now, till I can get it up on a stand and cleaned up.

40H134714

from intake manifold am aassuming this would be a part number, don't know?B1231718-E

Thank you

 

Not the original motor. It is a 455, I bought from a junkyard do not know what it came out of. Am trying to find out what year it is. The numbers came from between the 1 and 3 spark plugs.

 

70 455

:bglasses:

If you look between the rear plugs, you should see a two letter code with three digits near. That will tell you the HP. :Smarty:

 

Yes the intake number is for a 1970 so the 0 before the H probably means a 70.

 

If it is a 455, that number should be found on the top of the bell housing, 12 o clock positition. Under the 455 number you'll find the block casting number, please post this on the board.

For a 1970 455 it should read: 1231738, but for some 1971 455 engines this number was also used.
Best thing is to look at the two letter engine code:
If it starts with a S, it's 1970.
If it starts with a T, it's 1971.

1231718 is the intake number for a 1970 455 CI engine.

 

Found SF 3 and what appears to be a 9. Thanks for your help. I am trying to figure out what I have and will nedd to do to rebuild it.

 

sf code

Nice find ! I believe it is for the electra,riviera,lesabre -360 or 370 hp

 

It means it came out of a Boat like a Riv, Electra, Estate Wagon etc.

 

SF engine code is for a 370 HP 455 with 10.5:1 compression ratio.

 

Thanks for the help. Now I all I need to do is get it rebuilt. Have about a million more questions on that subject.

 

John,

That will result in at least 4 million answers on this board.... :beer
Will this 455 go into the Skylark when it's finnished ? :3gears:
