I want to build a new motor for my '95 Flareside. Thinking of buying a shortblock assembly and then add the rest(cam, heads, headers, etc). My question is what would be a good cam for 302 with standard pistons and maybe some GT40 heads? Plan on keeping the same fuel injection setup. Want a little bump in the idle but don't won't to effect performance. Was thinking about the B303 Ford performance cam. I want to improve performance but still drive it every day.
