In fact every one that I have done made more. Currently, I have one on a bb with rpm heads and a flat tappet cam running a best of 5.88 at almost 117mph footbraking. I am anxious to see what it does when we transbrake it. that equates to about 750hp. car weighs about 2850

Its hard to beat the Weiand street TR with the D shaped ports, I ran a solid tenth & 1.1/2 MPH quicker over an M-1 single & 750 PF carb, & that was with minor tuning on 2 crappy 600 1850 holleys. On top of that, my 60ft. fell off by .03-.04 on the runs from the added torque & lack of a good suspension, plugs were stone white back in the pits. Ran a 10.87 @ 123.58 on a 1.628 60ft. with TR Ran a best of 10.98 @ 122.09 on a 1.58 in same air. 75 Duster, 451 10.87 @ 123.58 NA 97 Z28 6sp., 12.01 @ 115 on a 100 shot 71 Swinger. 360 magnum. 12.58 @ 105 78 cutlass, 469 BBC. 12.70 @ 108 on street tires. http://www.youtube.com/watch?v=Z2kqNmMfheU

But I've run more than few dyno tests where the tunnel ram is a dog. Some of the old school tunnel rams are very weak when compared to a good single plane intake." I am Currently running the Indy 3X with a Quick fuel 1250 on my 572.It runs pretty good! If I did not have so much invested already I might be tempted to try a tunnel ram but I would want to pick up a lot more than a tenth or so or "The juice would not be worth the squeeze" for me! I do think they look awesome though! Mike

I was planning on -10 from tank to pump, -8 from pump to regulator (two port) and -6 to each carb (3/8" hard line to each bowl). Would I be Better off running a four port regulator with -6 to each bowl? Carbs are 4150's and the combo should make 700-750 on pump gas.

What kind of 750's should I look at? Holley, quick fuel, pro systems.......... My custom built Quickfuel 750's had the wedge shaped tunnel ram floats, the carbs were pretty much dead-on right out of the box, never had to mess with idle or anything once it was set, best carbs I've ever owned.
