The 230 was/is a nice smooth powerful small six. But, in pickup use they are just marginal in my opinion. Lots of power for the size but require much higher RPM to develop the power as compared to the 235. My granddad sold a 61 1/2ton and bought a new 63 and just hated it for farm use. He was used to just idling around the pasture feeding hay from a big load and pulling out of the pasture with 2-3 big steers in the stock racks at very low rpm. The 230 just wouldn't do that like the 235. He bought a 250 in about 65 and was happy with the Chevy again.
