holley 4160 externally adjustable metering block

http://store.summitracing.com/partde...5&autoview=sku

does anyone have experience running these type of metering block? I'm just learning about tuning, and it seems like a great deal to be able to not have to swap jets.

heres the manufactures site

AdjustaJet

I've been using those for about 7yrs now on a daily driver and they work geat. Very easy to tune. I also used the there CircleTrack blocks on a race engine and I loved not having to drain the bowls everytime i changed jets at the track. I think they have Drag blocks also. There different colors and can flow more than the stock AdjustaJets.
Holley made something similar to this a good while back. There's had an electric motor on the adjustable jet and you could tune them while driving from inside the car. I think it had a Air/Fuel meter too. Saw some on Ebay a few years ago.

once you get it adjusted for optimum power and performance you should not have to mess with it, right!

So what is the difference between finding the right main jet size for optimum power and performance and adjusting the needle on the Percy block beside fuel draining on the manifold and the time involved and a few more bucks.

Yes correct.

No difference. Just alot less mess & time. Less wear & tear on your carb threads. It does allow a slightly finer adjustment.

Don't forget changes needed for altitude? Go on vacation and leave from 1000 feet and end up in Colorado at 5000 feet for a few weeks, a simple tweek of the screw and bingo bango, all better.

I dunno, looks pretty cool to me.
