06 SG been having some problems with my motor-131 cyclerama just replaced the oil pump, cams, pushrods and lifters. Got on it this morning 1/2 mile from the house it's making loud strange noises. I've put a lot of $$$ in this motor -- don't want to put anymore dollars in it.

Thinking about replacing it with a S&S 111 that I can get for $6200 with a three year warranty.

Anybody got thoughts about this motor?
