Engine Starting Issues

What's going on guys. So check this out,

We tried to start the motor today for the first time. and the engine imediately backfired through the carb. we tried adjusting the distributor both advancing and retarding and it does the same it fires and spits smoke and fuel through the carb. we checked all the spark plug wires and they are in order on the Distributor.

I'm pretty sure the timing chain is on correctly a friend put the motor together that knows what he is doing. When i set the plugs in place I turned the motor till cylinder 1 was at the TDC noted the placement on the Dist Rotor and set that as cylinder 1. and set the plugs accordingly.

And while it cranks the timing on the crank pulley we got to 0 degrees.

If it helps, Engine is a 318 and heads are 360 magnum.

I'm running full MSD setup, blaster 2 , distributor and 6AL. Wires

The engine will not start at all it just spits smoke out through he carb. is there anyway the dist is set in wrong?

Thanks IN Advance
