Flowkooler High Flow pump for the Oldsmobile 455 engine has a CNC machined billet impeller designed with an increased vane count and a reduced plate-to-impeller clearance. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids.
This pump is commonly found on cars without AC. The taller hub heights were used with AC cars to advance the fan blades forward 1/2". They needed just a little more to cool with the demands of AC condenser and pump 1576 fits that set-up.
FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Olds Rocket engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

Beware of the Brown Crazy Horse version.
NOTE: This review is COLOR SPECIFIC and concerns the Brown Crazy Horse version of this shoe.
I am a loyal Florsheim customer having purchased Florsheim Imperials in years past. They are a fine shoe. However, I have to admit complete frustration with the Florsheim Berkley Flex Penny Loafer in "Brown Crazy Horse." The photos in the listing show a shoe with gloss...a shine. The photos on the box show a shoe with shine. Don't believe the photos. "Brown Crazy Horse" is, at best a dull matte finished leather. If you want a classic penny loafer with the classic Florsheim look this is NOT the color to choose. When the shoes arrived and the shoes did not match the photo on the box, I ignorantly assumed it was merely a case of the wrong shoes in the box so I exchanged them for another pair, which was a big mistake. It is Florsheim's incorrect photo and box label that caused me the inconvenience of going through two pair and then having to return both. I would assume other colors are as pictured in their listings because I cannot imagine that every Florsheim Berkley Flex Penny Loafer is a dull matte finish. I'm sorry that I do not have photos of the dull finished shoes. You'll have to take my word for it. They are a matte finish at best.

Just right, great quality and value (in the price)
Size: 11.5 X-Wide, Color: Burgundy
Exactly what I'd expect from a Florsheim. I'm delighted.
Folks, let me share one mistake I made on my way to a good fitting pair of shoes. I ordered some in my size (I have a big foot, especially in width). I ordered what I thought I needed and it came in wide enough, but too short (the short was the surprise), but we all are told: "Manufacturers vary in their sizes not only from each other but from shoe model to shoe model." I want you to know I believe in that when it applies to clothes, especially children's and womens fashions in my life's experiences, but NOT with shoes, especially main-brand-deluxe. I ordered the next half-size up and now I have too large, how can that be? I found out when I pulled the paper stuffing out, in particular the LAST glob that extends from the middle to the toe, that it WASN'T the last glob, there was indeed a rather small glob still way down in the toe, almost pointless for this minor bit of stuffing being separate from the other, but it was. I had already innocently troubled Amazon with returns of shoes that would have fit, so I'll keep the half-size too large as a life lesson. I ordered this pair in the size I believed I was all along and viola, a good fit. What changed? When that last toe piece of paper wadding that's hard to see and even harder with a big hand to reach, the shoe fit perfectly. That's a lot of trouble because of a small piece of paper that was hard to see, but that's why I write this review for you so that you can make sure all the paper is really out when you already think it is. Amazon has been good enough not to hold me accountable and in return I'll not only repeat buy, I tell you of my experience.

Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.
