RE: 428 dyno results

On the dyno we used straight race gas initially. Then went to a 50/50 mixture of race gas and 92 octane street gas. We were going to go to straight 92 octane, but we found the motor liked only 37 degrees total timing. That is the advance I had been running it on the street with straight 92 octane unleaded anyway so I didn't worry about it. It hasn't had any detonation issues so far. This summer will be a better test, but I'm not worried about it.

It was dyno-ed with open headers because the mufflers wouldn't fit around the dyno

What are the other spec's on your motor? Are the heads ported? Compression? Carb? Headers?

Nobody seems to like the Edelbrock cams. It is definitely an "old school" grind with slow ramps (lots of advertised duration, not so much duration @ 0.050"). Still you ought to be able to get at least 425-450 hp I would think. Did you degree the cam? Maybe it's way retarded.

Did you dyno your motor or does it just feel down on power?
