I have a 52 Belair with a 235, mild cam, dual intake with Carter/Webers, fenton headers, engine was balanced when rebuilt.
Stock inclosed drive line, 355 rear end, 27 in tires.
I am at 2900 RPM at 65 MPH and it just purr's along.
Has plenty of power to maintain speed pulling hills.
Driving the freeway's I get 16-17 MPG, if I have a lot of around town driveing it's not so good (i like to hear the glasspacks).
I think balancing the engine makes a big difference.
The 235 is never going to be a real power house unless radical things are done to it, but I find mine is good for what it is used for in a 3600 lb car.
I also have a 46 pickup that I'm going to start a frame off on this winter, I have a 323 posi traction rear and a 261 eng, I'm still reasearching what I want to do with the transmission.
