No I've never tried anything but Edlebrock's/Carters and a Thermoquad on this motor. I have no doubt a new $5/400 carb might fix it, as I have a Speed Demon 850 on a similar 451 I own and was able to tune it. But I just want this car to run nice so I can sell it. BTW it's a 64 Polara vert so it just needs a nice cruiser motor. I just need to find a deal on a stock type cam....


Take care,
