I 've read a lot of problems with T & L. And a few with the EXACT same cam and lifter problem. If this motor has been broke in and dyno'd, how is it going to wipe a lobe now??? It's been supposedly broke in and then flogged on a dyno??? Did he change the oil before he got it? NO reason since this is a brand new motor. balanced, blueprinted, and don't last 60 miles. He gives a 12k warranty. With less than 60 miles, it should have seen more thrashing on the dyno than he EVER will on the street I don't see it. If it were NEVER broken in by the builder, then yes, maybe the owner had something to do with the cam problem. But, broke in, DYNO'ed, ????? As in 6k rpm's Even if the motor sat for months after break in, unless you put the wrong oil when you got it, I don't buy it. Did you change the oil when you got it? Before start up? The backwards head gasket is all you need to know the quality of the shop. And NO, I don't buy a pro engine builder, MISTAKENLY put the gaskets on BACKWARDS!!! This is a supposed PRO engine builder. Maybe me or you might, but I doubt that also, since WE know, 'Do it right the first time' I don't see any love coming your way..... You spend more locally, but you can be there at break in, so you KNOW it's running right BEFORE you take delivery.
