I am going to get the Summit SUM-6400 cam and lifter kit as it is better than stock and you can't beat the price at $117.My question is how should I install the cam for my application...straight up or advanced?Also, it is a cast crank motor...what should I do about balancing?I don't have the rods yet, but when they arrive I will weigh both new and old assemblies and post up the difference.Also any thoughts on what I should do about a distributor and the ignition timing.Thanks in advance for your help!
