\"Power Timing\" I need the procedure for 'power timing' my 350. I have an aftermarket harmonic balancer as well as other aftermarket parts that make the stock timing marks and specs irrelevant. I've been able to get it close by just plain feel, but what the actual procedure. Do you disconnect the vacume advance?? Would it be better with the K5 fully loaded or mostly empty? I've searched all posts and found a few references to it, but no specifics. Thanks all.
