Did the dyno take into account the different gear and final drive ratios of both cars? If not, then the dyno is pretty much invalid.
funny you should mention that. this is an excerpt from elisetalk.com:
">>>Yeah, but "in a given comparable gear" is the key. You wouldn't gear the two engines the same, and don't forget that the chart stops 1.5krpm short of the dizzy (I really like this izzy/dizzy slang) readline. So if you re-geared the dizzy, the crossover would be at the "equivalent" of 5krpm.<<<
I suppose one thing we can see is that compromises were necessary down low so that things worked better up high. Someone is working on a comparison taking road speed in given gears into account. In the mean time...stay on the high cam when possible!! It would be nice if Dizzy's 4-6000 range was a bit stronger, even if that weakened the extreme low end a bit. A hotter low lift cam could do this. The top end of this motor is fine from my perspective, but I'd prefer less of a jump when the second cam kicked in. In my on-the-road 2nd gear accelerometer test, the car could gain speed noticeably faster from 50-60 MPH than from 40-50 MPH. In the area of about 15%."
