Got a 351W question...

[Schiffy]

So i need some help from my fellow stangers... I was offered a fully built(carb to oil pan, with headers, brackets, accsesories, even a belt) 351W for $500. guy said he rebuilt it 1000 miles ago, then it was yanked and put off to the side... the guy told me i could have it for $500. kinda better than my 306 Idea i had, as this is ready to bolt in... all he said he suggested was replacing some of the gaskets while the engine was out of a car, just so i didn't have to do it later... my question is... what do i need to do to my '95, or do i need to buy, to make it a complete swap? this is something i'm really interested in, but want all the info i can get first... so... tell me what i need to do, and what i need to purchase to make this work(i have no ac or smog pump, all i want to keep is power steering)

lets see...swap headers use the ones for a fox... you got the oil pan and distrubitor ....umm im thinking lol i will write more when i can think of everything you need

well, if you want to stay efi, then you would need to go with a trick flow intake set-up or a gt40 intake set-up from a 1st generation lightning.

If you want to go roller (assuming the block he has is not roller) you would need to completely dissaseble the engine and take it to a shop and guy a roller conversion kit.

i also think the oil pump driveshaft, oil pan, timing cover and dizzy would have to be changed to make it work. theres a tech article about this is here somewhere

When you say "carb to pan" do you mean it actually has a carb and you are going to ditch the stock computer?

Yes, I'm going from EFI, to a carb. going to rebuild the engine coming out of it, to a 306, and put that in the back of the garage for later. I know about the headers, but other than that, i don't know there's much difference. i know it'll bolt directly into my K-member, and it has distributor and all... he said as it sits right now, give him 2 hours, and it could be in a car driving down the street. LOL... why would the oil pump shaft need to be changed, and also the distributor? I can see the pan being a possibility. but the other 2?

If it's complete, carb to pan, you'll just need some headers that fit and you'll need some hood clearance. Your fuel pump will have to be changed, unless you want to run a regulator with a return. Probably cheaper to just do a different pump.

Once you go to a 351 based motor, you'll never go back.

+1 on what TRUUBLE said. You won't need any of that computer garbage.

I've got to do some homework, and see what the engine came out of, because if it wasn't Mustang based, then i'll need a new oil pan right? I found out i can use my same power steering, i just need to buy a new bracket for it from FMS. I'm going to google it, get all the info from the guy in about 20 min. as i'm about to dress my son, but I'm planning on putting it in like it is for now, and down the road stroking it out... :boink: :boink:

On another note... While i was doing some research for 306's yesterday, can't remember if it was The Racers Edge, or DSS... but one of them makes a complete forged kit for my 390FE engine. So after the 351 swap, should it go as planned, I'll save up for the 390, and do the work on the new 306 myself. lots of projects, and idea's, just not enough money... the 351 has become #1 priority, and the 390 will take over after that(as it doesn't need to be started till beginning of next year) the kit i found for the 390 though, makes everything ALOT easier...

How will my fuel lines bolt up to a carb? i was thinking, trying to figure out if i'm going to have to swap some lines over, or add lines, or what... going from a fuel injected car, to a carb... how will the fueling issues convert over? also... I doubt my radiator will work, will a 2 core be sufficient enough, or will i need a 3 core? I've been reading the different forums, and I've printed up an ass ton

Stick with EFI. Putting a carb motor on it will effectively remove any value the car once had.

I have no plan on ever selling the car, and Should i sell it, it's paid off, so anything will be profit. I couldn't careless about value... I'm all about Horsepower, and speed, and making more of both... Carb is cheaper as of right now, because that is exactly how it sits, fully built engine with an air cleaner, all the brackets and pulleys, and it even has the belt on it. guy told me if i wanted to dyno the engine, all they'd have to do was hook up the battery, and the cooling, and she would start right up...
I'm tired of EFI cars... I've had a few, and i've had a few carb cars... so with a non value based opinion... How will i need to hook up the fuel lines to the carb?

 

[Paul]

You'll need a carbureted fuel pump, new regulator, either replace the lines or get the aeromotive EFI adapters that plug into the stock fuel lines, and so on and so forth.

Do you know hat heads/cam/intake are on this thing? If it is a mild 351 you'd be better off just modding your 302. Even though it has more cubic inches, it may not make more power. I'd hate to see you whore out a car, then be disappointed.

paul is making a lot of sense right now... you should slow down and consider the points he's bring up.
tired of EFI? huh??? I don't get that.... what are you tired of? the pcm that controls everything without any help or adjustments from you? or maybe the part where it diagnoses itself?
well for 500 bucks i'm thinking its a stock 351 so i'm just gonna say to be careful and find out the specs.

 

[TRUUBLE]

That's what I got tired of. :boink:

 

[Schiffy]

It has an edelbrock intake, Holley 4 bbl, World Heads, and Hypertectic(sp?) pistons. stock rods and crank... I can't remember the cam off the top of my head, but i know it has had the lifter valleys machined so you can use the Hydraulic lifter cams...My plan was to purchase one and stroke it to 408 anyways, so why not make the jump now...
I WAS going to build a 306, but this is cheaper than a 306 shortblock used by about $100-$150. plus like i said, i will eventually stroke it out. not tired of EFI, more so... I just want to give the carb a shot... I have a few ideas with my hood and the air cleaner. LOL... I was told by somebody fuel pump wise to buy a Holley "blue" fuel pump, and i will need to slightly modify the in-tank hookup, but nothing I couldn't handle.


OH, and the reason it's $500, is somebody paid him to add these new parts, and couldn't pay up, so he just gave it to this guy... he just want was was "owed" so he can get rid of it.

Hahhaha
As if it would have ANY idea what is going on under the hood of that thing. :rollinglaugh:

 

[Schiffy]

I don't think there's a system out there that could tell you what was going on under truuble's hood

 

[Paul]

Not really. Any of the good aftermarket standalones couldn't handle it no problem.

FAST XFI, AEM, Big Stuff 3, etc...

If they can manage 6 second car running 240 mph, Tad's little 9 second NA motor would be easy. Of course, he'd have to switch to EFI instead of mechanical fuel injection. For his purposes though, I'm sure he's happy with his setup.

Me personally though, I would never build a racecar or streetcar without EFI. It will always be able to do things that carburetors and mechanical fuel injection can't.
