Great link Eric.

I never thought the fly's would be a power adder? Always liked the taller velocity stacks but never liked cutting holes so the only time I ever used one was in a V8 Vega I removed the hood from for a summer.

The biggest surprise for me was how the drop baskets with a good filter and a top breather robbed nearly 19hp horsepower placing 18th. I added one to a stout big block in my 55 so that it would clear the hood and swore it was the shiznit. Apparently Not.
