Ford 351W engine ID
I have a friend with a 1976 Ford Bronco with a 351w in it. The motor is not original and he was told it came from a '69 Ford car with a 4 barrel. He would like to know if this is true or not. His engine code is: C90E-6015-B . If anyone knows how to decode engine codes can help us out, please get back with me!!!

Yep sounds like a good engine Very high Nickle content. Good for up to 600 HP.
I just sold my 69 block this weekend. I miss it...

Ok so this answers one question we had, now how can we tell if the heads match the motor or not? I don't think that makes much difference in the long run, however he wants to know if the motor is pure '69 or not. Any ideas?

Look at casting # on heads
C9 = 69
D0= 70
69 heads are supposedly the favorite OEM head.

Any early 351w Heads with large Plugs are the fav's. All have the dogleg coolant passeges. The years that are 4V are 69 - 74.
Any of these heads out flow the GT40 heads with a little bowl work.
The later truck heads are OK just need more work on the exh. side.

Thanks for the help guys, my buddy and I have cracked the case and we have determined that he has a full '69 motor, which is what he wanted. I think also he has decided to go ahead and do a full port/polish on the heads with a 3 angle valve job as well.

Nice to have that engine. I think it was 265 HP new.
