Thread: Suffix Code - What can solve this 1957 mystery?

Tweet

Casting code: 3731548 (1957 283 small block)
Engine Assem / Suffix Code stamp: FI02F

From what I understand (correct if wrong please):
1) F = Flint plant
2) "I" was actually a "1" in the 50's code stamps
3) Therefore manufacture date is Jan, 2nd 1957


What is the F suffix code? Is it powerglide? Any idea what car this was out of?

Powerglide, 2 bbl., cars and Corvette.

.

Any info that will differentiate between a car and Corvette?

The cast date is: L276

Engine mounts are both on the front engine block
