Max Power 164.4 - Max Torque 180.6
This is about a 20 HP increase over my last dyno with the Aussie Head.
The weather today was in the 90's with lots of humidity. I think if it was a cooler day the results would have been in the 175 range.
We also CC'd the chambers. The Aussie head was 55 cc's and the Aluminum Head was 54 cc's. We did not use the head gasket that Mike provided, but went with a Felpro instead. It was about .022 thinner. The intake ports were very mismatched on #3 and #4 using the OZ250-2V intake. Pushrod holes should be moved .125 closer to guide rod and .125 closer to each other on each pair. As far as spark plugs we used Autolite AP 5224.
Any thoughts? Michael
