I replaced the Rochester 1bbl on my 235 with a Holley/Webber 2 barrel. I really cannot believe the improvement in driveability, power and economy. I just towed a u-haul trailer 400 miles in it and even with the bed loaded up, still got 17.3 mpg. I came back the same 400 miles, averaging 60 to 65 mph and empty, got 18.4 mpg in a strong crosswind.
This is compared to only 13 mpg with the vastly inferior Rochester.
