Good Initial Timing and Too much Total Timing Problem. Seeking guidance to minimize total timing. 1969 Swinger 340 4 Gear

Well got some more data. I changed spark plug wires today then checked my timing again.

Initial Timing 12degrees at 700rpm
Total Timing 40degrees all in at 2100rpm.

Both number are with the vacuum line disconnected and plugged at the carburetor and distributor canister.

Please let me know what I should do? Should I try retarding the timing 2degrees so I’m at 10 initial and maybe total will be at 38degrees? I still have a bog to get the car rolling from a stop(4 speed manual car). Thanks
