351 Small Block Dyno Shootout: Windsor vs Cleveland - HorsePower S16, E11

Part 2 of HorsePower's dual Ford 351 project, as the guys complete the build of a Cleveland engine and then turn their attention to the Windsor engine. Using some original parts and aftermarket heads and intake, the guys transform the Windsor into a better-performing Clevor (or mock Cleveland).

[@jimmytew9468]

I had a 72 Gran Torino Sport with a 351 2v 4 barrel back in 1979. It belonged to an elderly lady that was in charge of our public library and she bought it new from the Ford dealership in town and the did all the service on it. It only had around 28,000 miles on it when I bought it. All I did was put a set of headers on it. Had some work done on transmission and put a rear end out of a ford pick up and some rims and tires. And at 17 years old I had a Hot Rod. When I sold it in 1983 it had 120,000 miles on it and I took great care of the car there was not even a scratch on the car. That's one ride I wish I had not sold. Those 351 Cleveland were great engines if you kept them serviced.

Would have been interesting to leave them both with factory stroke and compare the benefit of the canted valve head on the cleveland vs the traditional style head on the windsor.

[@johnringel9892]

I am confused. What were they comparing ? A stock Cleveland rebuild with a hotter roller cam , and in my opinion, a poorly chosen intake manifold. In the other corner a Windsor, that is no longer a Windsor. With the entire Hi Po parts book thrown at it. A better " Comparison " would have used a Windsor, with the best " stock " Windsor heads, same cam profile, same intake design, same C R, and perhaps most importantly. The same cubic inches, and equivalent dollars spent. I feel confident, in a fair fight. The Cleveland would have prevailed.

[@williamglass7806]

you said that right

[@dannythompson1948]

At 5500 rpm each cylinder is firing 11 times a second... That's 2 revolutions of the crank per firing, so to acheive 5500 rpm, the crank spins 22 times a second, working in unison with the cam and heads to control the flow of gasses. These engines doing this for hundreds of thousands of miles is truly impressive.. God i love combustion engines.

[@numbnutz9398]

I've learned so much this episode. A stroked motor with aftermarket heads and cam and intake can beat a stock motor with just a cam! Amazing! What are they comparing here? The Clevland 2V vs 4V made sense. Why not just compare different engine mods to this engine. And if the Cleveland was made for the street why the single plane?

[@sarcastomimic2683]

The Clev build was a total mismatch of parts. not only a single plane intake, but one designed to run 2v heads, and a smaller carb. Clev's are designed for high RPM power. If they had put the 4V heads with a 4V single plane intake and 850-900 cfm carb, with large tube headers, and a more aggressive cam, it would have made the same HP and slightly lower torque between 6500-8000 RPMs. I built one like this 30 years ago and got 507 HP@7300 and 447 ft.-lbs @5700. It was a BEAST!

[@numbnutz9398]

@@sarcastomimic2683 it is like they were purposely trying to make the clevland look worse. I guess Edlebrock pays the bills so this was just a thinly veiled advertisement. Be nice if they said who was sponsoring the episode before hand.

[@Thundarr995]

@@numbnutz9398 I agree. They were promoting the 351 Windsor,which was stroked to 408 CID. No wonder it beat the Cleveland. There's hardly any 351 Cleveland's around anymore. If you do just so happen to find one they're pretty expensive to rebuild. You can find 351 Windsor engines no problem. These guys are just,basically advertising big names Edelbrock,ATI harmonic balancer & the timing pointer,whatever other companies they mentioned. Personally I don't really like this show. If you've ever rebuilt an engine,any engine performance or stock. They left 90% of the steps out. They didn't show degreeing the camshaft or measuring the pushrods,installing the adjustable rocker arms kit. These guys leave out alot of stuff. Makes people think they can just go out and buy all these parts and throw them together and it's gonna be great. Or like advertising that says adds 25% more power than stock. Then another one that says adds 25hp and another one that says adds up to 40hp and ...So on....by the time the engine was finished it should have about 2000hp. LOL!! The Chinese parts are the worst. One time a guy brought me a auto parts store rebuild Chevy 350 and a literal pile of parts. The Chinese aluminum intake manifold didn't fit and the Chinese chrome oil pan wasn't even flat and the bolt holes didn't line up well at all. Had to get the manifold milled and take an angle grinder to it so you could get the valve covers to fit.

clevlands were fords truck engine,built for torque,not,,racing.the windsor was the car/race engine.but the heads were crap.small/ strait valve train,no good.the 4v gtho falcons,ran at bathurst,those heads dont start working till 80 mph..the 2v & 4v heads have a hump in the exhaust,as i said,for torque,theres 'tongues',you can buy to smooth this out or grind them down,carefully..fact.a std 351 will run at 6k all day,where as a chev 350,or windsor,will lose its valve train.as there studded,.the 2v clevo is a very strong reliable engine,ive never had any problems with them,run forever,even when they use a sump of oil to a tank of juice,or,no oil pressure at idle,still go.which i think is a bad pump..chev 350 are a rubbish ,very old, engine design,cheap.454 better...but,,you cant beat dodge.i have a 340 r/t chall..i have a bronco 82,on lpg only,,351c,auto.stock,the 351 heads needed a valve job when i bought it,13 yrs ago,so i fitted 302c heads,12.1 comp,std,goes like a cut cat,cheap to run.never stopped except for 2 dead coils...all the tech has been there since day dot,to build well designed engines,but its production cost that limits what you get.desmodronic drive,ohc,3valves,fuel injection,alloy motors,all too expensive to sell cars..the range rover,layland,4.4lt,is an all alloy engine,very similar to a windsor.used in circle racing,,if,,you can find one..

[@AmericanThunder]

@@phantomwalker8251 351W is a truck engine, it has 3" main journals, which create too much heat to handle high revs. The cleveland, on the other hand, has smaller main journals, which allow it to rev higher without seizing them. The "racing" version of the 351W block has smaller journals for that very reason. A 351W has shit flowing heads, even the best 1969-1970 351W heads won't touch a 351C 2v heads, let alone the 4v/boss302 style heads. So I'm not sure why you think a 351W is a race engine, while the 351C is a truck engine?? There's no "low end torque" in cleveland heads, the ports are huge. The 351W heads make tons of low end torque, by comparison, because, strangely enough, the ports are tiny by comparison.

@@springwoodslasher79 Overall design and alloys have much improved but the same basic concept still persists. A single plane intake is for a higher RPM power band I.E. racing. A dual plane is more suited to regular street driving with the occasional drag strip trip. The guys on Engine Masters have done a comprehensive testing episode outlining this.

[@jeremiahpike6372]

The problem with the intake on the Cleveland was port size. I bet it is the size of the 2v intake ports not the size of the 4v intake ports. Power should have increased not decreased by adding increased airflow and it didn't. That says to me the airflow between the 4v heads and intake wasn't increased. I figure the opening up to a bigger size port in the head slowed the air down quite a bit from the smaller intake ports on the intake. Either way there is no comparison if the intake ports do not accurately match the cylinder head ports. Considering the smaller 2v heads made the most power the intake ports were sized to match the 2v ports.

[@la.fishsticker119]

The engine we see here is the remnant, a last gasp, a making do of what's left of what was once great. The 351C had all the elements that was learned thus far, four-bolt mains, the bore/stroke ratio, canted valves for 2.25 intakes, giant ports, closed "quench" chambers...it had everything...but had ONE "fatal" flaw. Someone within management made it a point, that under hood space was at a premium, & insisted that the exhaust manifolds "hug" close to the block. Somehow, some engineer while designing the heads, "curled" the exhaust ports to placate this "request" for tight fitting manifolds. Along the way, this one choice sabotaged the whole thing... no one noticed...the exhaust gasses would "stall" & "tumble" on the floor of the port, similar to a stalling aircraft wing, rendering a third of the port "useless" for flow.
