[1BADSTANG]

I can get a mint 0 miles WORKED 351 cleveland motor. From my uncle. For Nothing. Is it worth putting it into my stang? id like to get off of this 5 slow motor.. just kidding its a stout motor id just like to bump up the ci. Anyone know how involved this swap would be?

[Speedstang302]

im pretty sure its same basic swap as 351w's...ask ryan he has one in his red/black car...

[Goblin]

What year Cleveland? 2v, 4v?

Its basically the same swap as the windsor. You'll need a K-member, oil pan, headers.. (if your going carbed from EFI you'll need a throttle linkage) The Cleves have a different cooling configuration, so im not 100% sure, but i think you'll need different radiator hoses and radiator.

Man, more and more people are asking about cleves in foxes, maybe i should put mine in a fox.

There is room, but not for headers, not with out some cutting.

What do you have to cut?

[ryans88gt]

No the headers will fit if you get the correct swap headers without any cutting.

Also I'm not sure about the K-member needing to be replaced, i think you can find a rear sump pan that will work...maybe?

Also the EFI linkage will work on a carb car. I am still using my EFI linkage on my 88 gt. You just put a big loop in the linkage and it fits perfect.

I didnt know about the linkage working, i always thought you needed a different linkage for the carb.

I know that headers can be made to work without cutting, this is why i asked. As far as the k-member/oil pan issue.. my only argument is... What can swapping the k-member to a tubular one hurt? Your putting your front suspension on a diet, which is good because the cleve has a bit more heft than a 5.0. I really dont know of a rear sump pan that will work with the factory k-member.... i would like to know if there is.

Yeah, it wouldn't hurt to do a K-member..

It appears as though there is an oil pan and headers that will work...

Sweet. Im really intersted to see if that pan would work with a stock K-member. It doesnt say if you need an aftermarket K-member... so maybe that means you dont need one?

It looks like it is designed to work with a stock K-member, but it does say you need aftermarket motor mounts

I guarantee it will fit with a flaming river rack. That rack gives you almost an inch of extra clearance.

Right.

What does your GT run by the way, with the cleve? And whats done to yours?

[ryans88gt]

It runs mid 11s @ 120 mph with 1.5 60 foots. The heads currently on there are as cast 4V closed chamber heads, casting flash and everything, modified for adjustable valve train.

Its a 351 windsor block, 0.040 over with KB pistons, stock rods, stock crank, 1 3/4" headers, and a B&A track boss intake, with a mighty demon 650, the cam is a flat hydraulic that tops out at about 5500 rpms. Solid roller maybe in the near future to wake it up a little bit. I'm also thinking about some port work on the heads to close things up a little. My intakes cc were something like 255 or 265 ccs.

A 9.5" windsor block? You have to run a special intake right?

Thats an impressive trap speed for 11.50. How much does the engine weigh compared to a 5.0?

Well that's a good question as far as the weight. I estimate that the cleveland heads weigh almost 75 lbs each when fully assembled. So I bet the engine weighs at least 150 lbs more than a 5.0. But you are removing the upper intake weight, all the sensors, the wiring harness weighs like 25 lbs, the smog and emissions bull crap, I also removed the PS and AC. My 88 weighs in at 3090 lbs with a full interior, stereo, 8 point roll cage, subframes, 4 core radiator, and stock seats. Still has the bumper and support and foglights and all that.

Yeah I am using the 9.5 windsor block with a B&A track boss intake. You can use a 9.2 windsor aftermarket block with a cleveland intake and a valley pan. The headers work the same with either block. the 0.3 inches doesn't make much of a difference, I am using standard 351C 4V swap headers.

Oh yeah as far as the trap speed, it is a 5 speed car and I don't powershift. So I probably could see 11.0s with some powershifting, but I like my T5.

dont close the intake ports at all, use cam timing to overcome that port dimension along with rpm

Do you have any pictures of this?

I was expecting more than 150lbs, but thats really not bad at all considering the fact that swapping to a tubular K-member, A-arms and coil overs drops nearly 100lbs off the front end. Plus yanking all the junk you said above. I was really worried about weight. Do you have an aftermarket steering rack seeings as you dont have PS?

Powershifting + T5 = Not a good situation... the 120 trap speed makes sense now.

They kinda bell at the opening, I've heard that by just getting rid of the bell you only loose a few CFM and gain a bunch of velocity. I've also heard they work great @ 8000 rpms as they are or on a 408 without any filling. I don't really have any problems with torque, it has plenty of low end.

Just seems like a lot of people fill with epoxy and then work on a flow bench to port the epoxy into a fast and efficient runner. I don't know, mostly I want the exhaust side to be cleaned up, cause it is like a 90 degree turn. You know of anyone that does good port work on 351C heads?

[White Thunder]

why not get an aftermaket k member and slice 50 pounds of the nose of your car...there not crazy expensive.....

I have lots of pictures at home of the whole build, but none at work. Remind me later and I'll send you some pics.

I originally just kept my PS rack with no pump, but that got old in a hurry. I switched to a flaming river rack and it only requires about 25% more effort that it did with the PS intact. I am still using the stock K member, but a fiberglass hood and bumper support removal would make the car lighter than it started out as.

Sweet, i'd love to see them. I really think using my cleve for a fox build up would cool, and different. Cheap? No, but still different. What ratio is your steering?
