Need help with 340 Prestolite dual point orientation

If your photo is with the engine at TDC for #1, I believe your distributor/oil pump drive is off a tooth. The rotor should point to #1 cylinder. Yours looks to be pointing more straight ahead. Once the drive gear is clocked correctly, the vacuum advance should be in a better position....which would be where the hose nipple is pointed a bit more toward the firewall.
