What led you to pursue the lunati that you went with.. sorry for all of the stupid ??? its just that I am sitting with a 60K miler and want to avoid a total tear down and am looking for some options of my own.
Thanks and keep us posted !

No stupid questions- I kinda just plowed into this thing. My original plan was to buy a Caprice, drive it through the summer, and do some mods this winter. I bid low (I thought) on this one, knowing it had some issues and ended up "winning" it. So, oh well, I guess this is the one! Didn't want to drive it w/the noise in the engine so I took it apart to see what its made of. I read up on the cams the G8 folks are using and all the DOD delete info I could find. There's so many choices.. Texas Speed, Livernois, etc. The "Little Lunati" just kept coming up. I wanted "normal" street RPM range, stock converter and rear axle. I picked that one because it seemed to be the thing to do at the time- the road is full of dead squirrels that couldn't make a decision - we'll see. quite a few people have been successful with it. I ordered mine from Rick Crawford, the advance is +0, If ordered from Lunati (#60516) its +4. For the tune, I'm working with a HP Tuners setup w/ support
CrashTestDummy- I gave some thought to the oil cooler. I think the coolant cooled cooler will be better than air cooled at maintaining the oil temp consistent- not too hot or too cold. As far as potential leaks that would be bad for sure! It is quite heavy and seems to be built well. I remember working at the dealer years ago and fixing a front wheel drive V6 with the strawberry milkshake for transmission fluid and the swelled up radiator hoses (from trans cooler leak in the radiator). That system cross contaminates because the trans fluid to the cooler is on the return loop and is only ~12 psig so fluid goes in the coolant until the cooling system heats up and pressurizes, then coolant enters the transmission. W/ the engine oil cooler, I'd think there'd be quite a bit of oil in the coolant and not the other way around as the engine oil pressure should always be higher than the cooling system pressure except when the engine is just shut down.
