So here is where I ended up for a street 496 blower cam. Will have it running in a few days. I replaced the gen6 timing set with a ton of slack with a SA Gear double roller. It is nice and tight. Maybe this thing will finally have enough vacuum to get my power brakes back on. Time will tell. Thanks to Wolfplace for the SA Gear info.
My objective is to put the power band down where I drive it on the street and cruising which is 2000-2200 most of the time. I never buzz it more than 5500-5800 and that is just to zing the tires a bit on cruise night. Done with WOT and breaking parts. Turned in to a wimp in my old age.
