Reply to "Quick Fuel vs. Demon"

Aloha Guys,

I thought I'd give a quick update: Talking with a few of the engine guys over here (and one who specializes in Fords), the consensus was that while vacuum secondaries are recommended for stock/moderate cam profiles, with the aggressive cam I have, mechanical secondaries might be a better fit, though it would take more tuning to get everything right.

That said, I took a leap of faith, and got the SS-750-AN. A couple days later and three jet changes, I'm real happy with the results. I now have snappy low-end throttle response, excellent mid-range pull and a big increase in driveability with no chugging off the line.

Best of all, I no longer have Pterodactyls flying out the exhaust!

One thing I did find: The ethanol-blended fuel had really done a number on the Demon. It's the first time I've seen rusted butterflies...
