| Mold number. |
| By Dave Shoe - 05/16/2003 12:49:53 AM; IP 216.243.176.34 |
It's a mold identification number used for quality control in the foundry.
If that's an original motor, that must be a 400-800 series heavy truck, not a pickem up truck.
The last FE went into the 1976 series 100-300 light trucks. I seem to recall that all 4X4s got the 360, but it should be considered a rumor if you hear it from me. You can tell by turning the crank near TDC, removing the bellhousing inspection cover, and peering at the bottom of the flywheel flange just a couple milliimeters to the rear of the oilpan.
If the flange has no features on it, it's a steel crank from a 361FT/391FT, if it's only got a 3/8" (or so) square notch cut into it, it's likely a 390 cast crank, and if it's got both a square notch and also a large semicircle cut out of the flange next to the notch, then it's most likely a 360 cast crank.
