Flathead or 351 for my 30 sedan

Have some questions even though I'm so darn far off making that decision..... but I'm struck by the memories of that great sound the flathead made in my great uncle's truck ....

1. Economically I have a feeling the flathead wont be inexpensive to buy then rebuild..

2. Then there is the difficulty in finding one in the first place..

3. I already own a 351 ...have the motorsport block ...steel crank and four alum rods and pistons... one clyinder needs a sleeve..have fully built TFS alum heads...etc

But that flathead sound has stayed with me ...

Any flathead advice???

Hi....I know the feeling, I,m building a '32 Victoria and wanted to run a nailhead Buick but I just could'nt find a good rebuildable core. I had 2 -'64 327,s small jrnl steel crank motors ...for free so I just built one of them, still looking for a 401 though. ( anybody?? ) Anyway go to w.FlatheadJack.com to see how much a flat motor would cost you to build. Sell the 351 stuff to offset the cost....if thats what you want to do. I saw '29 high boy with a nice flatty and a t-5 5spd, sounded *****in and the guy loved it. Build what you REALLY want, lifes short!!

That's what I'm leaning toward...thinking just the value of my built up trick flows might cover a huge chunk of the FH'ds.

G.L. with your VIcky sounds nice...

p.s Not being a chevy person ...what gives the old nailhead from buicks etc. such appeal???

flatheads what an engine good to see people still want to build them.
my thoughts are a flathead you better know what your doing or the builder had anyway.the down fall with them is if you wipe out a main bearing you have to have the babit repored. a 351 on the other hand you get a new bearing and get home not that you want to do work on the side of the road,my point is that the flathead though a great engine it's getting harder to find shops that accualy know whats going on and not one saying they can do it and send it to another shop and charge you for finding them.oh and not tell you thats what they did.
i would build the 351 and do something different,how about a bogas boss with injection

Motor City Flathead was working on a new Flatty block b4 they closed and the new owner was supposto get the block ready for production when he opened up the shop again. I'v heard that the french flathead block is the same casting as the old ford Blocks.

nailheads just look so cool, str8 up and down valve covers rather than Vee'd like most V8's. put 6 strombergs on 1 with some finned valvecovers and you got a motor everybody would look at

I would go with a Flathead if I was you. I also have a 1931 Ford Tudor and that is what I am going with. Of course I am building a nostalgic show car so I want to put an old engine in it.

The reson I suggest a flathead over a 351 is because of fitting reasons. The flathead is smaller and will fit almost perfectly in the model A frame. When you use a small block Ford, the oil filter gets right in the frame rail so you need to relocate it. The headers also get in the way of the steering box. We built a 1932 ford at my job using a 302 small block ford and we had a lot of fitting problems. We also needed to have the water pump machined because it was getting in the radiator. The engine was almost on the firewall.

You might prefer to use a small block chevy as it will fit really good and you won't have any problems finding parts.

Note ...
1) a Model A ( 1930 Ford ) is smaller tan a 1932 Ford in the engine compartment
2) a 351 is physically larger and longer than a 289/302

So you know fitting the 351 in a Model A would be real challenging ...

I've very little experience with Flatty's. Except, if you check my age you can be sure I remember them!! Anyway -- They are a little different. Not the easiest, most straightforward, or simple engine to build. If you are a really good wrench, or want to buy from Flathead Jack, or some othe specialist. Go ahead. But if you are at the "experienced hobbiest" level, I would not venture into the project with a flattie without doing lots of research. They are wonderful old motors. But, a good flattie today will cost a pretty penny to buy, even as a builder, if you find a solid core. And check out thoroughly the differences in the french block before pursuing that option. They are not the same. At least, that's what my expert friends tell me.

Whatever you decide -- Good luck with it!!

Pat

Keeps those guys from saying "chevy 350" when people ask what they're running. Add 355 and 383 to that list as well. They're as common as Honda Civics, and for good reason- they're plentiful, inexpensive, and there's a bazillion parts available for them.

Try finding an Edelbrock R4B for an AMC 360/390/401... ugh! *looking... looking... I know I should get brakes first on the Jav but an elusive R4b would be sweetness!

A few years back, Street Rodder did a series on building up a Flattie. It might be a good informative series to read through.

1 1/2 wider, taller, but not longer. Identical length block and accessories. Accessories from 289 fit W except brackets into head holes.

94-95 GT 5.0 HO and TBird HOs/ last Explorers have the short serpentine front dress that is about 1 1/2 shorter overall and easily adapts brackets right onto W. Watch that damper balance.

THx ....Duece...I know your a chevy man, and was hoping to stay with a ford engine, but problems with water pumps and oil filters.??? NOT

This project is challenging enough as it is.

After reading some discussions on the current flathead situation I've backed off that possibility ...can become a money pit real fast.

But to resort to a 350....like seeing your self coming and going.

Have to admit that chevy makes great heads those raised ports just love to eat Fords raw.

Really have to give this some thought.

Thx again all
