I have a 71 455 Buick engine in an a-body right now that is all stock except for headers. I have an 800 cfm Q-jet that I bought from Poston's that seems to be working fine & I still have the orig distributor w/points. I have about 100 miles on the points & I have a dwell meter & set the dwell at 30 deg like the emissions label says. Now to my problem...in low gear when I stomp on it, it pulls fine until 3k & starts to break up up to 5k, I manually shift the th400 into second & its fine in all the rest of the gears. My timing is set at 12 degrees before tdc, total timing I'm assuming is around 30 to 32 deg. Also, with the vacuum adv hose disconnected, where should the timing be set?
