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

They sure did the Cleveland dirty.

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.

I was expecting a stock Windsor 351 vs a stock Cleveland 351...🤔

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.

Just build the damn things the same way! That’s a comparison

That Cleveland build needed much more compression and much more cam to really shine. That single plane intake manifold is designed for much higher rpms than the engine was built for. If you had went with 11.5 or 12:1 pistons and a 7500+ rpm camshaft, it would have really woke up with the 4v heads.

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.

Back in the 80's no one would think of the 351 Windsor as a performance engine. A lot has changed.

This is literally an apples to oranges comparison.

This whole "comparison" was not much of a comparison.

Senseless comparisons, this show is just a aftermarket advertisement!

That intake manifold needed to be changed to the 4V version to really see the horsepower and torque of the Cleveland. 2V is right for the street for sure, but that 2V manifold is choking the potential of the Cleveland.

Im curious how this is a direct shootout with one being a stoker...

Guys, it's not a Windsor after you've converted it to a "Clevor." I think you have lost sight of the windsor/cleveland comparison entirely, especially after stroking the windsor up to 408ci ahd changing heads to a completely different design. What is the point of the comparison when you change so many things in such an asymmetric fashion?

Love to see PowerNation do a US-built 351C vs an Aussie spec 351C ! Our 302 clevelands provide the 6" rods and small port 56cc heads that produce a pretty unique and punchy motor. PAVTEK do a nice CNC rework of the 302 C head that works well with the combo. 💪💪

Cleveland, canter valve heads and ports, 11 to 1 compression these things come alive, along with a little exhaust port mods

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?

I've seen street Cleveland's make way more power!! With the right combination of parts, pound for pound the Cleveland will outshine the Windsor when it comes to building power!

Both are very sweet sounding monster engines! Music to my ears !!!

I've had several cars with 351 Windsors and one 351 Cleveland and I'll take the Cleveland any day. The Windsor is a good engine but the Cleveland is in a class by itself, it is fast and tuff.
