Question on my 1966 Fairlane 390 engine
I have a 1966 Ford Fairlane with a 390 engine. I noticed on my engine that it has the stamp "357". I freaked, thinking the guy who rebuilt it had switched engines. When I asked him, he told me that there was no real 390, per say. He said that all of them were 357's bored out to a 390. I am not that savvy as this guy, whose been rebuilding engines since I was a kid. Is there any truth to this? I would really like to know.
Thanks. warren

Never heard of a 357. I HAVE heard of a 352, which is what the 390 was derived from.

Not certain but I believe a 357 is a 351 bored. As far as I know there was no 357 in '66. You had in the Ford V-8 engines 265, 289, 302, 352, 390, 400, 406, 427, 428, and the 429. Although I think the 406's were dropped in '63.

look real close, and make sure it doesn't say 352. i've not run across an fe block that didn't have that on it. only way to tell for sure is to pull the oil pan and look at the crank, or you can pull a head and measure the bore x stroke.
332- 4.00" bore x 3.30" stroke 352- 4.00" bore x 3.50" stroke 360- 4.05" bore x 3.50" stroke 390- 4.05" bore x 3.78" stroke 406- 4.13" bore x 3.78" stroke 410- 4.05" bore x 3.98" stroke 427- 4.23" bore x 3.78" stroke 428- 4.13" bore x 3.98" stroke so really, it isn't the bore so much as the stroke. i bet you dinner that it sez 352 on it.......

all 390 and most FE blocks have 352 on them.

Even if it is a 352 it has been swapped. '66 Fairlanes came with either a 6 pop or a 289 and the GT's came with the 390 or the 427. Nice looking car. I'm not a Blue Oval fan but have always like the '66-67 Fairlanes.

The 352 is just a casting number in the front of all FE blocks until the later versions came with a different # (can't recall off the top of my head but, I believe it is backwards 105). So the block is probably a 390, don't let that # be any concern. I have 3 FE's in the shop now a '67 428PI,a '69 428 CJ and '64 390 and they all have the 352 number. I think it was used to identify the FE external casting forms.
The really important part,the heads, would still have to be on it for the exhaust to fit. The Fairlane and smaller cars had a different bolt pattern on the exhaust side of the heads to allow a more streamlined manifold for the shock tower clearance. Last edited by woodz428; 11-03-2003 at 01:43 PM.

My 390
Thanks for your responses gentlemen. Question for Poncho. So the 390 is a bored-out 352? It makes sense and is in line with what the guy who built is said. Is there any website I can go to in order to verify this? Thanks.

Haven't a clue buddy, I am a Chevy guy at heart. I just seem to remember a lot of stuff about the motors from the 60s.
The 352/390/428 line of motors kind of went out of favour in the 70s, I think when they started getting good power from the small blocks. Of course, now I am going to hear from all the BB Ford guys....LOL.

My 390
Well if any of you know of anywhere I can verify this, then please let me know. I was stationed in the Panama Canal while this was done. Any help is appreciated

You can check the FE forums. There was 390 though, the guy that said there wasn't is wrong. 1966 was the last year of the 352 and they shared some of the same external castings but it is more likely that the 352's were 390's not bored as much. Prior to 1966 there are separate casting #'s for 352s and 390s. An engine is either a 352,390,410,428,427, they are made that way and aren't just different bored blocks. If you get the casting # from the side of the block (it will be a CXXX-XXXX-X number i.e. C6ME-A where the middle 4 #'s aren't cast) then I can tell you what year it is and likely whether it was a 352 or is a 390. I'm not sure what the big deal is. If it was a 352 block someone bored to make a 390, as long as the correct year casting and the 390 internals were used no-one would know. It would be the same.

OK, I have a question about the block sizes that has my curiosity aroused. I have never heard of a 332 or a 410. What did they come in. I do know, and forgot earlier, about the 292 and the 312 which came in the T'birds. I had a 312 in my '57 fairlane. I know that the '63 Galaxies had the 406's but were dropped in favor of the 390's. Were the 332's and 410's truck engines? I used to have Fords waaayyy back when I first started driving but not for years. Thanks for the info people.

332s and 410s were car engines. The 332 was actually the first FE variation in 1958, the 410 was a Mercury only engine in 1966 and '67.

Thanks Woodz. That clarifies some things. One thing I do know is that I know nothing about the Mercs.
