This motor combination, 347 FRPP sportsman block with Edelbrock RPM heads, RPM II intake, complete aeromotive fuel system from tank to fuel rails, 75mm TB, Motorvation custom chip, complete MSD system with digital box, Grantelli MAF and much much more, has run as low as 11.90 @114.5. It just all of a sudden decided to give me fits. I have replaced the distributor, the MSD box, the EECU IV box, the custom chip, the MAF, the coil, the spout, and the EGR valve. Still the same out come. When the spout is put back in after setting the timing, the engine will hardly run. If I remove the spout the motor runs OK at LOW RPM, but there is nothing at higher RPM. When I check the timing there is NO advance. It feel acts like something is shorting out or going to ground with the spout installed.Thoughts?</blockquote>
