im thinking about changing out my 2 barrel carburetor to a 4 barrel to get out of the hole better when im loaded heavy. has eneyone done this, or should i leave my motor alone.
I would tend to agree with bubba, I am not sure it will make that much difference. You might be better served by changing your prop, essentially giving you a better "low gear".
Over on Breezeworks.net they specialize in these motors. I saw some pics of some sick 470's. The 485 was rated at 10 more hp. If you want to sink some $ into it there are some things you can do. When i have to break mine down i am going to try to mate an aluminum head to it.
