460? 352?

I just bought a 74 F250. Now the guy told me it had a 460 but I noticed that it says 352 on the front left of the block. I was going to post a couple of pics but the posting rules indicate that I can't. Also it has 5 bolts connecting the valve covers.

It's not a 460...it's an FE engine, either a 360 or 390 (it could also be a 352, or even a 428-swapped in). Most of the bare blocks of FE engines have 352 cast into them because it's the starting point for the engine sizes.

FE refers to Ford-Edsel. The 332/352's were introduced on 1958 Fords, the 361 was Edsel's FE engine. This 361 engine lasted only one year. The 332's were discontinued after 1959. The 390 was introduced in 1961 on cars, 1968 on F Series trucks. The 360 was introduced in 1968, and was only used in F Series trucks. F Series trucks used the 352 from 1965 thru 1967.

Post the VIN from your truck. The 5th digit is the code for the engine...and that will tell what engine it originally came with.

Is there an easy way to figure out what it is?

You can post the 5th digit of the VIN, but that'll only tell what engine it came with when new.

You have to measure the stroke to know for sure. Someone will chime in with the how-to do it.

A lot of people mistakenly say 460 when it is in fact a 360.

My guess is 360.

352/360/390 are identical on the outside.

You have measure the stroke through the sparkplug hole to verify

or

Get the IDent number off the crankshaft.

If you use a wooden dowl through the spark plug hole, you can measure the stroke. If it comes to about 3.75" then it will be a 390 or a 427 If your a lucky one. A stroke of 3.5" will be a 360,352,or 332. iam going to bet it is either a 360 or 390.

The 5th digit is R. The person I bought it from didn't speak english so I had to use his daughter as a via. At first she said it was a 460 and was a new engine but later he/she said that the motor was original. Probably could have done as good just talking to myself.

The 4th digit is the engine code .. not the fifth.

R translates to San Jose California

Thanks for the de-coding. These FE's can be pretty hard to identify. You know one of the reasons I bought this truck was I thought it had a 460. I didn't really look at it too close obviously but this 390 4V, headers with a shift kit actually does pretty well. I recently sold my 2000 F150 4.6 and bought this truck just because the old school engine design and power delivery it so much better for trucks. I always hated having to wait for my MOD motor to wind up so I could get moving.
