?? Y Block Question ??

How can you tell the differance between a 292 and a 312 ? I have a 60 ford f100 and really dont know much about the motor but its supposed to be rebuilt. Thanks already .

 

Here's the best place for that info:http://www.ford-y-block.com/techincal.htm

1960 should of had a 292 but that doesn't mean anything this many years later, find the block numbers, certain blocks have better chances of being a 312(but all still could be a 292)

 

Thanks, That helps !!

 

No trucks came from the factory with 312's, but it is possible some one put one in later.

 

I think the 312 was not made after 57 and all were 292s untill the end in 64.

 

Thanks for all the replys . It helps a lot .

 

I don't know, Ford stopped in 1957 but Motors Manual says Mercury used 312 thru 1960.

 

Ya, i was told the 312's came in the cars only, no trucks.

 

There should be a marking aroung the distributor

The engine in my Fairlane was mistaken for a 312 because a 312 manifold was installed at some point - My tuneup guy pointed it out that it was actually a 292.

 

Difference between a 312 and a 292?

Dirty2, call Ted Eaton, he's near Waco, and a Y-Block guru. Super nice guy, will talk your ear off about them, full of information. I called him on a whim on a Sunday afternoon and he blew me away with information. My 292 will be sent to him shortly for some magic.

Bore, stroke, valve size etc...

 

Ted knows his shit. not only y-blocks but all ford engines

 

312's were the base engine in Merc's up to 1960.

 

From what I remember, you have to drop the pan and check the main caps. Look for it on Mummert's site.

I was told my 292 was a 312 - just sweetened the deal to me. Of course it was a 292. I guess the 292 makes a better block when you bore it out. The 312 often suffers from cracks.

 

What got me to thinking was that it has a 4 bbl on it . But I'm not a ford guy. But things can change . Thanks for all the help. And I will be calling Ted .

 

3.800 bore= 312. 3.75 bore = 292

 

Fresh rebuild on the motor so I wasnt wanting to take it apart .

 

312 has bigger mains than 292, there was trouble with pulling threads in the 312 blocks when torqued down because of less material in the main area after enlarging the main diameter.
Ford's solution was lower torque numbers for the mains, what people are doing now is using 312 cranks and having mains and rear oil seal area turned down to 292 size and use in 292 block.

 

Danny, Look at John Mummert's site, lots of good info there and look un tech section, has way to identify the 312 crank by marking on back end of crank http://www.ford-y-block.com/yblockpage.htm
