I'm not sure about this and would like to know
Will gear effect MPH? I can see it effecting ET by 60 ft'ing better but HP calcs don't ask for gear. they just ask for HP and weight and since this car in question doesn't MPH either I have to question whether gear is the obvious reason. If anything, a really effed up converter might be the problem
like Cab said, maybe the filter is the problem but at 9 lbs crossing the line, Could that really be the problem? Now, if 9lbs is to much and your flooding the engine, I would think if your dumping way to much fuel in the motor it could be washing the plugs clean but they would probably be dripping but would cause the engine to be way down on power.
taking it to a chassis dyno is something I would do. maybe your timing light is off from the one used on the dyno. are the secondaries opening? when you figure this out, i'm sure we would all love to hear the results

I'm sure his gauge says 9# but I will guarantee that it isnt accurate otherwise it would be pouring past the needle and seat... it could very well be too small of a needle and seat but its the same stuff that he ran on the dyno.... basically you used THEIR ignition and THEIR fuel system so those are the places I would look ![](/ubbthreads/images/graemlins/wave.gif)

You either have a really "Happy Dyno", or a serious problem somewhere.. ![](/ubbthreads/images/graemlins/1343795-scratchchin.gif) Never heard any complaints on here about Barton's dyno.. ![](/ubbthreads/images/graemlins/whistling.gif) Since it's a new converter, and a Power Glide, I would definitely look there first.. ![](/ubbthreads/images/graemlins/scope.gif) I put a new converter in my 540" B1 w/Glide 3000#.. (thought it was making close to 900hp) and it went 9.40 @ 143.. ![](/ubbthreads/images/graemlins/shock.gif) Immediately took it out, put in a trusted converter, and went 8.78 @ 153+.. Fuel filter in front of the pump.. ![](/ubbthreads/images/graemlins/tsk.gif) 2800# and 875 hp should net you at least 8.90's @ 150+.. ![](/ubbthreads/images/graemlins/thumbs.gif) BTW.. That thing should stall at least 6400 rpm imo.. Chris.. ![](/ubbthreads/images/graemlins/wave.gif)

ok, that's crazy. was the converter slipping that much or was it just so tight that it bogged the engine down? was the converter fixed and did it work after that?

Turned out to be a bad stator/sprag combo.. ![](/ubbthreads/images/graemlins/shruggy.gif)
Brand new converter.. Was fixed, and went .05 slower than my current converter, but same mph.. ![](/ubbthreads/images/graemlins/1343795-scratchchin.gif)
But, it was .1 and 1.5-2 mph slower t-stop racing.. (Supposed to be a copy of my other converter, but with a sprag, to get more mph) Didn't happen.. ![](/ubbthreads/images/graemlins/whistling.gif)
Glides and converters are very touchy.. But once you find one you like, you'll fight to the death to keep it..

The new converter`s a Neal Chance 9" custom unit (NOT a two piece unit ) I called Marty and that`s what was spec`d out with ALL my car`s specs as well as the dyno sheet . This one`s not gonna be easy !!!!! Thx for you`re help ! chryco ![](http://i1131.photobucket.com/albums/m553/debobs557/IMG_8942.jpg)

Honestly I don't think it's a power problem from all you've posted, it's a chassis, gearing, converter problem.

Still sounds like a converter issue to me. If the car is not spinning the 60 foot is a little lazy even for the MPH that you are running right now. WIth the glide my guess would be your shift recovery is pretty slow, Would be interesting to see a time slip to see how strong the car is pulling from 1000 to 1320 feet to get an idea of how much power the car is actually making. With out more data pretty tought to diagnose further but the combination (independant of the dyno numbers) under your conditions should see another 10 MPH and run closer to 8.90s (if the chassis is sorted out as well). Similiar to others experiences with my old car just a converter and some chassis tweaking netted a 5 tenths improvement. That was with a lower powered wedge combo going from 10.3 to 9.8 MPH increaseds 7 MPH. Went from an 8 inch converter to 9 inch and never looked back.
