He is a photo of the 1" hole in the china wall and the opened up lifter valley holes I did in the response to advise from Todd Marsh and others. Without these mods (and the deck mods) the engine ran out of oil in 45 seconds after startup with oil pouring out around around all the lower valve cover bolt holes. This was after spending a day trying to get the engine in the car. I had 3 brands of starters. None would fit the block. A lot of time was spent grinding and trying different starters. By the way, the engine sat crooked in the car. I worked a month on that. (Never did get it straight.) I can't say enough bad things about Russ.
