The install is real easy me and a kid that has zex on his car did the install.I would get the zex spark plugs(2 steps cold,you dont need to gap them),iv got an msd 6a igintion,blaster 2 coil , plug wires(magnocor),and iv got an air fuel gage but you dont have to have one.If you go 65 or 75 shot you need to retard you timing(65=2,75=4).One last thing,make sure the are no restrions in your fuel system,make sure the fuel fillter is chaged and fuel pump is working good.And you cluch is in good shap,mine was in bad shap before the zex,now its almost gone,i guess thats next for me??
