Not all perfomance stuff but they were all good investments. I bought a new crane adjustable vacuum advance, and accelorator pump cam set, a four hole 1" carb spacer, and new jets for my carb. I am going from 69 primary and 72 secondary to 72 primart and 76 secondary. Any body deal with rejetting carbs? Should I expect a good increase in power with the new jets and carb spacer? Oh yeah I also ordered a pair of 235/60/15 bf goodrich radial ta's.
