Narrative:

On departure from sna runway 19R and complying with SID, ATC cleared us to 6000'. ATC then advised us of traffic which we tried to get visibility contact on. At 6800', I noticed the altitude deviation and took corrective. ATC then cleared us to 7000' and told us to maintain present altitude (7500') and clarify our previous clearance to 6000'. We acknowledged that we were only cleared to 6000' and ATC stated that there was no traffic conflict. The rest of the flight was uneventful. There were a couple of contributing factors. Due to the noise abatement procedures at sna, it requires an abnormal climb out procedure, which neither one of us had performed before, substantially increasing our workload. Also, the altitude alerting system on the large transport consists of only a light on the altimeter. The aural warning sounds only after a 300' deviation has occurred, which neither one of us remembers hearing. All of the other aircraft I've flown have had visibility and aural warnings. Of the 7 different types of aircraft the company operates, the large transport/widebody transport fleet has the highest # of altitude deviations. This was my initial operating experience trip and I realize that an increased altitude awareness is required for this aircraft.

Title: DEPARTNG SNA, FO FLYING IOE, OVERSHOT ALT ASSIGNED.

Narrative: ON DEP FROM SNA RWY 19R AND COMPLYING WITH SID, ATC CLRED US TO 6000'. ATC THEN ADVISED US OF TFC WHICH WE TRIED TO GET VIS CONTACT ON. AT 6800', I NOTICED THE ALT DEVIATION AND TOOK CORRECTIVE. ATC THEN CLRED US TO 7000' AND TOLD US TO MAINTAIN PRESENT ALT (7500') AND CLARIFY OUR PREVIOUS CLRNC TO 6000'. WE ACKNOWLEDGED THAT WE WERE ONLY CLRED TO 6000' AND ATC STATED THAT THERE WAS NO TFC CONFLICT. THE REST OF THE FLT WAS UNEVENTFUL. THERE WERE A COUPLE OF CONTRIBUTING FACTORS. DUE TO THE NOISE ABATEMENT PROCS AT SNA, IT REQUIRES AN ABNORMAL CLB OUT PROC, WHICH NEITHER ONE OF US HAD PERFORMED BEFORE, SUBSTANTIALLY INCREASING OUR WORKLOAD. ALSO, THE ALT ALERTING SYS ON THE LGT CONSISTS OF ONLY A LIGHT ON THE ALTIMETER. THE AURAL WARNING SOUNDS ONLY AFTER A 300' DEVIATION HAS OCCURRED, WHICH NEITHER ONE OF US REMEMBERS HEARING. ALL OF THE OTHER ACFT I'VE FLOWN HAVE HAD VIS AND AURAL WARNINGS. OF THE 7 DIFFERENT TYPES OF ACFT THE COMPANY OPERATES, THE LGT/WDB FLEET HAS THE HIGHEST # OF ALT DEVIATIONS. THIS WAS MY INITIAL OPERATING EXPERIENCE TRIP AND I REALIZE THAT AN INCREASED ALT AWARENESS IS REQUIRED FOR THIS ACFT.
