I have about 375 horse and 400 ftp torque. Was built for bottem end to mid range. I seem to get good mid and top but dont think the bottem end isn't were it should be.

1. Do I need to up grade to a Hei or Msd distributor and how many volts?

2.I have it set at base time 12 degrees Atdc.

3. Problem still running alittle rich, I have a 600cfm edelbrock turned out 1 3/4 factory set, also turned it back 1/2 to see if it helped.

4. In park I have Ideal speed at 750, Please help try to fine tune it! Thanks
I am with Delawarebill I hope #2 is a misprint. If not try setting it to 12* BTDC and use a vacuum gauge hooked to a vacuum port on the intake manifold. Advance distributor for the highest vacuum reading then move it back 2-4 in./hg. If engine pings decrease until pinging stops. Also you can adjust idle screws on your carburetor to the highest readings.
