Guys: I have a 69 vert with a std 350, 47 heads, modified with a q-jet on a Pontiac cast iron intake, and cam specs .407/.411 and 200/210 duration. This combo is bolted to a TH350 and 2.78 open rear(AC car) I have an offer for a pair of #18 heads(350 HO from 68). I feel that my carb is already on the rich side, so it might work without rejetting? Should I get a bigger cam? What about advancing it to get max low end torque? What ignition curves are needed? Any opinions are very welcome!!
