trying to find Casting numbers to find out if my 390 casting match with stock 390 engine specs. Or if i have 360 parts on it. So please anybody has any info on 390 casting numbers Like crankshaft numbers and so on. HELP!!!

 

On mine I could not find casting numbers while it was in the vehicle, when doing a pan gasket. I did see numbers (2U) and I guess this works out to be a 390 crank. Maybe you can see some 2 digit numbers on your crank?

 

I got this number c3aee off a 390 crank out of a 63 and half galaxie. On the 390 i had in my truck, which is why i'm looking. I did not find any casting numbers on it.

 

That corresponds to what you said about the car.

What do you want to know about it ?

the crank the came out of the 390 in my truck had a different number it read 90993 or 90983 not totaly sure, it was kinda hard to read. But thats what it read.

 

I don't have anything that refers to those numbers.90993

The other one though C3AE-E is for a 390.

Here's how you identify it as a 390 or a 360/352 crank. The 352 and 360 share the same stroke, but the 360 has the 390 bore.
1. Lay your crank on a table or on the floor next to the wall. Or, put a board up against it.
2. Make sure one rod journal is parallel to the floor, and touching the board or wall.
3. Measure the distance from the wall or board to the center of the journal next to it. Write it down.
4. Now, without moving the crankshaft, identify a journal on the opposite side of the crank, which is parallel to the one touching the wall. (180 degrees around the crank0
5. Measure the distance from the wall to the center of this journal. Write it down.
6. Subtract the first measurement from the second, and this will be close to your stroke.

The 352/360 used a stroke of 3.5 inches, and the 390 used a stroke of 3.75 inches.
If your measurement is about 3.75 inches, you have a 352/360 crank. (Of course, it was made for a 360 if made after '67. I do not know if the forgings or other manufacturing processes were different between 352 and 360 crankshafts.)
If it is about 3.75 inches, you have a 390 crank.
7. You can get a more precise measurement by measuring from the centers of the two journals.

Alternatively, you can re-attach a rod and cap to the crank and do it this way:
1. Attach the rod and cap. With or without piston is OK.
2. Lay the crank on the floor.
3. Rotate the crank so the rod is at it's highest point away from you. Make sure the crank journal for that rod is parallel to the floor. You can let the rod/piston touch the floor, though. Mark the crankshaft's position so you can be accurate in where you lay your crank for step number 5.
4. Mark the spot on the floor where the top of the rod/piston is. I recommend you pivot the piston, if possible, so that the side of the piston is lying flat on the floor.
5. Rotate the crank so the same journal is now closest to you, parallel to the floor. Make sure the crank is in the same spot as before.
6. Mark the spot on the floor for the top of the rod/piston. Make sure that the piston, if still attached, is in exactly the same position on the rod (they pivot, you know) as it was in step 4.
Measure the distance between the two marks for the top of the rod, and you have your stroke.

Be careful for both of these, the difference between the two is only a quarter of an inch, so you need to be as precise as possible.

Good luck, and let me know if this works!
