It's not as the consumption would disturb me much because the engine really pull strong and run on german highways a topspeed of +200 miles. I am just curious to know what experiences about oil consumption other cast iron sleeves LT5 owners did.

Are you actually burning oil? Bluish smoke and smell out the tail pipes? Or are you blowing oil through the PCV system?1 quart every 650 miles is a bit excessive. Even with 140,000 miles I was losing may be a quart every 1,000 or so.
