Have a question about timing on my 302.

Let me start by giving some info on the engine.

93 ford 302 roller engine
Holley 650 DP, mechanical secondarys
Edelbrock Performer rpm manifold
Edelbrock Performer rpm roller hydrualic cam - 298 dur. 520 lift(newely installed)
Crane energizer roller rocker arms (newely installed)
Msd 6a ign
Msd pro billet distributor w/ mechanical advance



My question arises from trying to time the engine after I have just installed the new cam and roller lifters.

I have tried to set the timing at the recommended setting of 12-14 BTDC all the way up to 22 BTDC. The engine is popping up through the carburator at both settings if I press reletively quick on the gas pedel and the throttle response is not very good at all.

The Balancer that is on the engine only goes up to 20 either side of the zero mark so I have no idea on how you check the total timing or if I even can with this balancer.

I have pulled the #1 spark plug and checked AGAIN that the piston is on the compression stoke and that the timing mark is at zero at TDC.

I am at a loss of which way to time the engine to make the carburator backfires go away and to have the eng. run well.

Any help is appreciated....

Thanks in advance.
