i read that the cleveland motor is better just because it can breath in stock trim better than the windsor can. does the cleveland heads fit the windsor? or where are some cheap heads i can get my hands on? and how hard is it to port or flow my own heads?

 

Hmm, to me the question would be do you want to build power na, or blower? Dollar for dollar, you will get there faster with a blower, and make more power initially. I just acquired a 93 lightning, and having been there done that with mods, I am just going to buy a vortech and leave it alone from there. Should make a nice easy 350ish to the tire, and be fun to drive...

 

Yes Cleveland heads can be bolted to a 351 Windsor engine but water passages need to be modified and a special intake needs to be used. Edelbrock is now making this intake.

2V Cleveland heads are preferred, which are the same as 351M and 400 heads and cheap.

Search under "Clevor".

 

so you can also use the 351M and 400 heads on a windsor, for a performance gain??

 

From what I hear the 400/351M heads are way better than the GT-40's, and I heard that they can be put on the W motors(Cleavor), but people said that it is hard to do and not worth it, but I can find complete 351M 400 motors for $100-$300 I would think if it was easy to make the EFI work with the 400/351M heads then it would be worth it, thats assuming the machine work doesn't cost that much, and that the Heads are as good as people say. I'm sure Conanski could school us all on how this would or wouldn't work out.

 

well, I will just go give him a shout and find out.

 

hmmmm so i found the "clevor" intake manifold but its for a carb and i have efi. i really dont have plans of switching to carb since the milage would be even worse. Yes i know that the milage will suffer with more performance parts so i am looking for the best of both worlds here. if push comes to shove i will go with carb but will want a new every day driver.

 

two barrel or four barrel heads?

 

Swapping a 351m/400 motor into a vehicle equipped with a 351W isn't easy. For starters, they have different bell-housing patterns, so you need a different trans. Some people claim to have made good power with those motors, but more will tell you they aren't worth using as a performance platform.

 

im keeping my windsor. thats that! its my baby. plus all these things that i hear about how its such a good engine makes me adore it more. with that said im really interested in the cleveland heads and found some for less than 200 rebuilt.

 

I would do a whole lot more research before you go buying cheap heads off of e-bay. they might be cheap but thats what you'll get, cheap! google search 351 forums. If you want real horse power and torque then spend real bucks do it once do it right. This is just my $.02 worth

 

I'm not saying scrap the windsor I'm just saying using the 400/351M heads on the Windsor block for a gain in performance, but it's probably better to find aftermarket heads anyway.

 

You definitely need to do some more research into what all is required to construct a "Cleavor". Use the search function here for starters. While the fact that you need a different intake manifold has been mentioned, what about pistons? I haven't looked into it, but next you have to find headers made for a Cleveland in a vehicle never equipped with Clevelands, if those will even work.
Cleveland heads are O.K., but won't hold a candle to a decent set of aftermarket aluminum heads. You might as well go with GT-40P's if you're ready to deal with header issues.
You also have to consider the whole motor as a package, and look at the cost of getting all the parts necessary to build a balanced engine.
The bottom line is to research, research, plot and plan, and have the goals and costs all figured out before you buy the first part- you can't have a ham and cheese omelet if you get ham and cheese but forget to buy the eggs.

 

yes i have done a lot of research and have actually found diagrams showing which holes to plug, drill and also the modifications to the head gasket and the required pistons for the build. i dont have the link as of now but i can find it for you if you need. at the moment the heads on ebay cleveland heads, All matching items for sale. its the third one down. while i am interested in this build im not sure if i will have the money to machine the block get the heads, pistons, rings, crank bearings, intake manifold, long tube headers, short custom exhaust with glass pack and carb that is required with the Edelbrock intake manifold. oh and probably a new water pump here in the next season. i think that i have done a lot of research on this subject but because of the costs im only brain storming, dont get me wrong i would love to pull the engine and paint the block, bore it .030", put on nice aluminum heads with hydrolic rollers, high compression pistons and the works, but the budget isnt there, actually no where near there.the heads i found initialy look in great shape and look as though they were rebuilt. so the most i could learn about these heads the better, such as porting them myself if anyone knows fill me in.

 

i found these very usefull when talking about the clevor mods.Clevor Head ModClevor Engine - Mustang & Fords Magazine
