The CDF suffix comes up as a 1985 small block 305. No CDF suffix for a big block according to that web site.

That's a prefix code. Suffix code will be three letters on the tail-end. What did the truck come with originally, a 402 or a 350?

The fender says 350 but I know this is not a small block

CDF132739 is the partial VIN from the vehicle the engine came out of. Check to the left to see if you can find the Engine ID number. That is what will have the suffix code that will tell what the engine is and what it came out of, as well as other related info. Your partial VIN decodes as
C = Chevrolet
D = 1983
F = Flint assembly plant
132739 = unique serial number, Vehicle #32,739

Find your casting number and narrow it down even further.
There's some pics in here for their locations.

That's not a suffix code, that's a prefix code. Where did that number come from on the engine?

**Speedracer39** · 12-28-2016, 01:28 PM

Machined pad in front of the passenger side cylinder head ------ I'm gonna clean up the back side of engine and try to get casting numbers-- it's a tight space

That's just the engine family it fits, not an indication of the engine displacement. But it does confirm it's a big block. But we knew that from the pictures...

You're looking for something like TO42TTBG
