I have a 56 Ford F100 that I bought with no engine. I wanted to get the best y block I could find locally to rebuild and put in it. So that leads me to today....there's a vintage/classic junkyard close to me that I wondered around today and I have a question about what I'm buying from him.

He had a y block that was already out but using the handy tech info that I printed out from Y Block Guy's site before I went, the casting numbers showed it was a 272. So I moved on....he had (what he said was)a 1956 Ford Club Sedan with the y block still in it. I popped the hood and noticed it had a 4 barrel on it. I then noticed it had Thunderbird badges on the front fenders.

What can you tell me about that engine? 292 or 312? My friend seems to think there's a good chance it could be a 312 but I'm thinking it's just a 292 for a couple of reasons....the casting number by the distributor is EDB with what looks like 17 above it. Also, I found a website that showed the "thunderbird" model sedans had 292's with holley 4 barrels. And I realize the only true way to tell is pulling it and checking out the crank flange or mains. I just know you guys are the gurus and might know if they ever put 312's in these cars or not.

 

Also, the data plate was missing so no way to tell so far exactly what year the car is.

I really appreciate anything anyone can tell me....it would be
fantastic if it's a 312 but I'll be almost as happy if it isn't. I just need to
find a set of G heads, good cam and headers to slap on it!!

 

Although, if I go with Mummert's site, it says that an EDB # if cast at Dearborn is a '57. So that means I might already have G heads right?
