My dad has a 1946 Chevy pickup with a 1961 235 inline 6. The motor has recently been rebuilt and it really runs great. Every day it runs better. I'm just curious what I could do to help it out a little bit? I'm not really into ripping it apart, so what kind of "bolt ons" can be done that would give it just a little more kick. It's never raced and really it's rarely driven. I'm just looking for a little something to make it special. As is it has a single carter YF carb on it. Would changing the carb be of any benefit or is that all the motor can breath already?

I was thinking about an MSD ignition system. I really like the MSD digital 6, however the truck is still on a 6 volt electrical system. We've looked at converting it over to 12 volt and have really decided that it's more trouble than any benefit would really be. MSD makes a box that is nothing more than a glorified transformer that allows you to step up the voltage to run a 12 volt ignition box off of a 6 volt system.

I was thinking that an MSD digital 6 and a very hot MSD coil would allow me to open up the plug gap quite a bit from the miserable small gap they are at now, this would give a little bit easier starting and some better throttle response. What about the distributor? It's a good old fashioned points style POS with a vacuum advance. Any trouble there with the MSD box?

I know not to expect a large power gain from an ignition box, but it certainly can't hurt anything. What do you guys think?
