When the Mustang was first equiped with a 302 or 351 engine, what type was generally accepted as a performance motor? in regards to whether it was an edelbrook or windsor or so on and so forth. Any feed back woul'd be greatly appreciated

#1 this is a v6 forum should post this in the v8 section but w/e


the 302 really dosent make much power untill you bore and stroke it to a 347 of put a power adder on it

the 351 is a very good v8 and theres to diffrent ones a 351 clevlend and a 351 windser

i think the windser is better out of the 2 and the make a shit load of Hp stock just redoing the top of the motor you can get 450+hps

The 302 (5.0L) is a very competent engine. Lots of parts for it, and the Small Block of choice for most street Mustangs (1979-1995) and cruisers (1964.5-1973).

The 351 (5.7L) does come in 2 flavours. THe Windsor(351W) and Cleaveland(351C).

The Windsor was built in Windsor, Canada. It is a 90* V-8 small block.

The Cleaveland was built in Cleaveland, Ohio. It is also a 90* V-8 small block.

The true differences are that the 351W shares heads with the 289 and the 302. The 351C has Oval head (similar to a Hemi). This head/intake setup provides less restrictive valving and intake runner path.

The Cleaveland is the "more bang for the buck" stock motor. I don't know about modified 351's, however the Cleaveland was the better motor originally.

There is a variety of aftermarket parts for both, however if you purchase one, make sure you get the right parts as 351C parts will NOT fit 351W motors and vice versa.

the cleaveland is not a small block. it is also not considered a big block but it is much larger than windsor. cleavelands are also much more expensive to build. the heads off of a cleavelad will fit on a windsor only if you have the proper intake. you also have to customize the heads a little bit

[JMack]

Like I said, the parts from a 351C will not fit on a 351W...

And it is a small block... Just because it is not a standard block (IE the 289 / 302 / 351W) family, will not cause it to loose the small block nomer. Both the Windsor and Cleaveland have a 3.5" stroke on them and therefore are both Small Block Ford motors. 4.0" and higher stroke signifies a Big Block Ford. All of Ford's V-8 motors fall into these categories (except of course the Flat heads, Y motors, etc...)

357 Clevor Build ford cleveland 351w motors head swap sbf
this is just a website i found and apparently it says you can put 351C heads on a 351W. but only if you have the propr intake and customize the heads a little

[Katen]

it is true you need a special intake or you can use these cheap looking spacers to fit the Cleavland heads on a Windsor block. but the Cleavland engine is harder to build, not much after market stuff in that block. i would say get a 351w an do some upgrades to it should make ya happy

[460brevill]

to put c heads on the w engine you do have to modifie and change manifolds,and both are small blocks!!

[69fastback]

lol...somebody said the 351C is "much larger than the windsor."

So one 351 ci engine is larger than another 351ci engine :

[460brevill]

the heads are largerbut deck says it is a small block.

[supermachone]

depends on which cleveland and which windsor it is whether its "better" the 351 cleveland with the closed 4v heads was a bad ass motor

[supermachone]

the windsor is a small block, the cleveland is a big small block

351 Windsor - 90 degree family
A basic 302 with extended deck height with thicker cylinder walls
Primarily the only interchangeable part are the heads with other small blocks from the 90 degree family.
In 1969, the 351 Windsor reached its' highest horsepower rating of 290 at 5800RPM



351 Cleveland - 335 series family
canted-valve cyclinder heads.
bore and stroke of 4.00 X 3.50.
a light weight block to beat.
one of the most desirable V8 engines Ford had to offer.
a two barrel or four barrel setup.
From 1970 to 1971 the 351 boosted between 250 to 240 horsepower.
