Nvm its a 400 big block i was kinda hoping for a 460 oh well is a 351/400 big block worth fixing up or just i get rid of it and get a 460? i got hooker headers for it so far and a mild rv cam

335 series is still a good motor, but I guess it depends on how much power you want to make.

Get Cleveland heads for it (Aussie 2v heads if you can find a pair), a decent 4-barrel carb, and open exhaust, no reason you should be pushing 400hp at the crank.

those wires look pretty

Damnit, that should've been "no reason you shouldn't be pushing 400hp at the crank", and it's too late to edit.

What about 650CFM Edelbrock Carb and a Edelbrock 400 Intake and hooker headers?thats what i was thinking porting and polishing the heads it has unless i can find some cleavland heads i will port and polish them but that will be my setup man that motor with the rv cam sounds awsome at idle how much u think i can put at the crank with all of that

[fordboy4rd]

Also u said its a 335 Series can u tell me what makes u think that, tell me a little about it i mean what makes it a 335 serious and what shows u thatr its a 335 series

[fordboy4rd]

I was told it has a RV cam / bored .30 over / rest is pretty muchg stock its a 351M it says ED hale or Hale ED performance on it i never heard of them but is this motor worth messing with or what? how much u think its putting out with its few mods

[tom2000r]

that's a torque motor

[fordboy4rd]

Thats probally why they call it a RV cam.. haha RV's are heavy.. sadly i think 351m's are junk but it runs very good and it sounds good

Side note: The 400 is still considered a smallblock, if it is a 351m/400 they are hard to keep together on a good race build. With high dollar internals it may be worth it, building a windsor will handle more in at a lesser cost. Running a canted valve cylinder head on a windsor will make huge amounts of low end grunt and pull off the complete pack. The number on a canted valve head are great than most aftermarket inline valves stock. The downfall is the open combustion chamber limiting the compression ratio.

335 series is 351C, 351M, and 400M.

The 351M is a destroked 400 made due to the popularity of a 351 displacement, and the dropping of the Cleveland.

While the M motors didn't make much power stock, they're horribly under-rated performance motors.

And no, they're not "small blocks". If you wanted to try and shoehorn them into Chevy-speak, they'd be a medium block, as they fit in-between the small block 289/302/351 and the "big block" FE motors and 385-series engines (429/460/514).

The best guy I know of to talk to about 335-series engine would be this guy: http://www.engnbldr.com/ He's mostly a Toyota guy, but he's done a LOT of work with other engines as well - he has a good writeup on the 335-series on 4x4Wire, but I'm not a member, so you'll have to go searching for it yourself.

ive always liked Small blocks like the 351W but u cant beat the sound of a big block.. actually speaking of big block i drove that vehicle today that has the 351m it sounds and runs great it wouldbe stupid to take themotor out because its a 351M so i will just let it be i guess and believe it or not.. my f150 beat it with a Rank of wood in the back.. and thats pretty bad

[white_fang]

dam that looks like an old motor i wouldn't trust it

Ummm. Wrong !!!! same headbolt patteren as the small block. They are a smallblock no matter how you face it. NOBODY claims to have a middle block.

[fordboy4rd]

i think its like a 70 model.. just the water pump looks old..lol i havent did anything to it anyways and i probally wont... i mean come on what good is a motor like that if the truck cant out put my other ford which has a 351w.. my truck stomped its ass with a rank of wood in the back.. that motor is pathetic..

So you're saying that head bolt pattern is what determines something to be a "big block" or a "small block"?

What about transmission bolt pattern?

What about block construction?

What about the rest of the architecture of the engine?

Motors are only reference as "small block" and "big block" because that's how Chevy did it. I don't claim anything is a "medium block", only that if you're so inclined to use the descriptions of small and big, that the 335-series engines technically aren't either.

Are you telling me that I can put 5.0 heads on a 400M? Because that's what it sounds like you're saying.

You'll have to forgive my rude behavior in my post from last night, I was drinking. No excuse, but I am sorry.

The 400m shares the same general head design as the boss 302, 351C, 351 Boss, 351m/400. They share the same head bolt pattern, however the water passages are different. Bolting a set of 351 Cleveland heads on a windsor block requires drilling of a water passage and a boss style/ford motorsports intake.

All your F.E engines are considered a medium block, so I stand corrected. You can see by bore spacing below (link) that the ford 239 C.I-400M C.I are compatable, however the Y blocks I do believe have different head bolt patterns.

Ford FE engine - Wikipedia, the free encyclopedia


So to answer your question, yes, with the proper drilling of water passages in a 400m block you could use a inline (Windsor) style head (Note: a custom intake would have to be made). However the opposite approach of using a Canted valve (cleveland/midland) head on a Windsor block would be a better idea. Using the yates pro heads as an example of the power that can be yielded from the canted valve configuration. The only hurdle to overcome is the open combustion chamber, it equivalates to a lower static compression.

If you are looking for a torque monster the 400 is one way to go, however they have small main and rod journals that are notorious for letting loose. The power is there, however that technology is out dated as better options are out there.

Hey, it's cool. It's the internets
