I already know it's not correct but what is it?

Just out of curiosity and wanting to know what I have under the hood what does this engine number say about it's origin?
I was told it was a crate motor (horse-traded with a guy for it).
I think it was originally a 1987-95, iron head SBC.
The middle two intake bolts are at a different angle than the rest.
He said it was a Jim Green "Race motor" but who's to say for sure...
TIA

From the forum on nastyz28,
Quote:
The suffix code book that I have lists UXH as 1990 Truck 350, 210 hp, auto tranny, from a 1/2 ton 4 wheel drive.

I'll check my Hollander when I get home.

Re: I already know it's not correct but what is it?

Why does it say "CLF" before the vin number on the bottom ?
Could CLF be the old engine's OE designation and then someone added it to the replacement crate motor ?

Re: I already know it's not correct but what is it?

I've been looking at that stamping since Lance first posted it.
Looks like OLF to me and I keep thinking it's a serial number from a marine application.
It comes very close to some Mercruiser numbers but I don't have a full list from all the other players in the marine business.
