I looked into the Hyland motor in the spring of 2006. I had them measure the motor as it was sitting in their show room. It was too tall for my tastes. I don't remember the exact height but it seems it was more than just a few inches above the decklid. Check out KarKraft for a full line of carbed motors too. They have dual quad, tri-power, and quad as well as a stack system. I wound up going with the fuel injected, dry sump, aluminum 5.4 motor from the Ford Racing catalog. Sullivan makes carb intakes for the modular motors.
