Any real racing engine has windage holes, the most apparent are motorcycles which don't displace a lot of air but at 14,000rpm they do move 100+hp worth of it and in a very tiny block!
I wish somebody would take apart one of these "01-02 LS1" engines to find out EXACTLY what's making them more powerful. Somewhere I heard they had LS6 intake manifolds, LS1 heads, LS6 block, thinner exhaust manifolds, and a cam imbetween LS1 and LS6... who's got the proof?

LS6 intake manifold is true. The exhaust manifolds used on the 01 and 02's are basically shorty headers. the cam also was changed for those years, to the specs of 207/196, .479 .467 on a 116. not exactly a radical cam by any means, but a little calmer than the one used in previous years.



However, please read... the LS6 block does not increase HP from the LS1 block. only difference is ventilation, which will not net any noticeable gains.

All dyno's are different depending on how it's set up by the operator. It helps to have someone else run on the dyno to compare to if they've dyno'd somewhere else, that way you'll know if it's dynoing high or low. It looks like you dyno'd higher than average. Even if you figure in a slight dyno difference, those are really strong numbers for a basically stock LS1.

Yeah, and I'll believe that joker when he gets a job at GM as one of their engine designers .
Doesn't increase horsepower, BAH HAHAHAHA, what an idiot. Horsepower is exactly what it does increase by improving the windage in the crank case. At higher RPM (where you're trying to get a peak hp number) there is a lot of air being displaced inside an engine. This windage gets really bad with big displacement and/or high reving engines. Trust me, an LS6 block will make more horsepower than a LS1 block or else GM wouldn't have done it.
