PS: I think I may have just noticed that the Quick Fuel 780's are vacuum secondary, whereas the 750's are mechanical secondary. Mine is mechanical secondary.

Finally a point we don't agree on. My history is vacuum secondaries because I think the engine via the vacuum signal knows better than my right foot if it can accept more fuel and flow rate.

As to how the FI looks, well awesome and it could add a little to performance. In the T-bucket group, so much coin is spent for the look of a bad engine and not much thought as to how pieces like tall tunnel rams effect the power curve. A couple of years ago at Fred's Fun Run in Sierra Vista, Arizona, Chris who owns a V10 powered Viper T-bucket brought his chassis dyno for free pulls. Many lined up, but after about a dozen pulls ranging from 119 hp to just shy of 200 hp, that line disappeared. Funny how a visually impressive intake that doesn't get on the pipe till 6000 rpm, combined with an ignored valve train (you can't see the valve train) that has valves floating before 6000, doesn't turn in big numbers. During conversation with my fellow bucket heads and they admit the visual is more important than the harmony of parts selected. For the street a good dual plane intake is hard to beat, but this low profile manifold that isn't in your face has no appeal to a lot of folks. The T-bucket rides for the most part are all lighter than 2000 lbs, so even 200 hp feels good. On a hp poll on a t-bucket forum, 18% reported running more than 476 hp and half of this group says they are running over 551 hp. At the last nationals we had 150 ts show up, this year it is almost in my back yard, Carson City, Nevada and Chris is bringing his dyno. We will now see all those so called 500 hp engines perform on the rollers. All the crazy "bench racing" destroys credibility for us that have 500+ hp engines.


Off soap box now.

This is Chris with his blown Mopar T, and he does produce big numbers.


And me laying down 320 hp with the mild mannered 383 that can plod at 1050 rpm at 40+ mph. Everyone knew from the cruise how quiet and mellow my engine was, they never expected 516 lb/ft at 2800. I think Chris's blown Mopar was the only one that beat me in torque and that was at a much higher rpm.
