Firecore Distributor Curve/Springs

Mine did not.
Ok, so here is where I am at, it idles the best at 22-23. I have two blue springs on the distributor. My curve comes in at 1800 at is all in at 2600 rpm and 45 degrees total timing. I’m pretty sure I need limit the mechanical? Where abouts do you think and how do the pros feel about the curve?

Edit: Specs might help.

440, 30 over, Promaxx heads, TRW -12cc Dometops, Mopar 296/.557 cam, RPM intake and Schumacher headers with a hughes 2800 TC and 3.55s . I don’t have a measure CR number but cranking PSI is ~160 across the board.

So you are saying the timing curve is flat from idle to 1800? And then gains 21-22 more degrees? My question is why is it not pulling timing quicker? It may not want all that intial if it starts adding timing way quicker than 1800.
Yes, you need to limit the advance.
