2.76 or a 2.94 gear? Both are highway gears and won't let a tight converter do much besides let the car mildly roll away from a standstill until the engine gets into it's power band but was it hesitating like an ill adjust carb will do? Press on the gas and the engine wants to die type of hesitation or just has no balls off of idle because of the highway gears and tight converter? I've ran plenty of cars with tight converters and highway gears at the track without hesitation but yeah, they didn't light up like a firecracker off the starting line.I hate it. My charger doesn't start moving until 1600 RPM; that's with a 440, 727 and a 2-something 8.75 rear end. Converter is rated at 2500 rpm and I bought it because the converter I had before it was too tight and I had a severe hesitation problem because of it...
Yup....don't know about todays newest converters but if they are still being made as they were a few years ago, then yup, a 2.71 gear is going to make that converter feel lazy until you get the rpm up.I had a 66 727 rebuilt, and the only convertor I could find(with the 66 and earlier input spline) was a TCI 3500 stall, I had a built 440, with 3.91, and I noticed a lot of what you are describing, during light driving.
I wonder if the 2.71 rear end gear is exaggerating the issue?
As with my previous 727 transmission I had a 2300 stall, and didn't notice any of that.
Been several years since messing with performance converters but if you are talking about what I think you are, those kind of converters are pretty expensive. Just another reason I like sticks. The stall is adjustable with a pedal and shift points are whenever you feel like it lolThat slipping feeling is what makes me hesitant about buying a higher stall converter. I'd read a good quality converter should drive as normal with no slipping feeling, until you stand on it, at which point it would quickly get you into the right rev range for maximum performance. What brand/model converter did you install?
