Intake manifolds

Ok, now to the problem.

I installed 318 heads on my ยด65 273 Barracuda. I got a Edelbrock dualplane with a Holley 600 dp carb.

The engine goes perfect with igniton 7 degrees before TDC, but i will not start.

Chaning igniton to zero degrees TDC it starts but it runs very poor.

What is the problem. Many motor-heads have been looking, but none could come up with some answers

:(

Just go with the Mopar Orange box and distributor. Never had ANY problems with that setup in my 65 Cuda Formula "S". Also have the same setup in my 66 w100 Powerwagon with a Poly 318.
