6 cylinder code help

[wthompson]

I found a thread that says get the ID number off the plate by the 6 distributor but I don't know what they mean and can't find any where that says what they mean. Can some tell me? F0625PF

Good job finding that code. That makes it easy.
F0625PF

F = Flint engine assy
06 = June
25 = 25th
PF = truck, 1969, 250cid, 155hp, 3sp, 1bbl

That's for 1969. 1968 also used the same PF code for the 250, but with a 4sp. If you want to make sure your engine is a 69, you can check the date code on the block. It's a CAST number, on the passengers side of the block. Right behind the oil dipstick tube. The casting number will be to the right of the date code.

Thanks Bruceman, where did you find this or do you just know it?

[bruceman1968]

I use a book by Mark Allen, but there are several sources online. Use suffix code or engine application code, as a search term. Along with Chevy engine or similar terms.
In your case I kind of did just know it, cause I have a 68 that had a 250 in it, code PF.

Thanks again and that's what I just bought a 68 with that.

Just reread your post and I don't know where I got 69 from. Oh well, 68 is the same only with a 4sp.

Makes sense, since the engine itself would be unchanged (250cid, 155hp, manual trans, 1bbl) and wouldn't know if it was a 3 spd or a 4 spd hanging off the back. That would allow them to simply reuse the same part number between '68 and '69.

Keith:
Iv'e got a '68 L6 292 F0627XAE, it is the original engine that was in my '68 C/10 Stepside when I bought it used in 1973. I can't find "XAE" on any charts.
Any ideas?
