New crate motor woes

I spent most of last summer installing a new MP 360 crate motor and getting the 10.95 Scallop clutch to operate correctly. I have driven the car less than 1000 miles since working out all the installation problems and changed the oil 3 times. A few weeks ago my wife and I drove to Santa Cruz for lunch in the Barracuda (about 50 miles round trip) and when we returned I found that the car had consumed ½ quart of oil. I had been keeping the oil level up by adding some from time to time but figured it was just slow to break in. I am going to take the car to Mopar Engines West for a leak down test to confirm there is a problem. I am not the first to complain about oil consumption with 360 crate motors and one of the guys on the Moparts web board lost his engine because he couldn’t conceive of a crate motor consuming that much oil so quickly. The warranty for a crate motor is 90 days from purchase, so I am likely screwed.
