You're right. So many, non-ZR-1 owners, seem to think it's high maintenance, no parts & a problem child. I get a little defensive. Sorry 'bout that.

As far as the cams, guess I always thought the issue was the lady in BG and start technique but sounds like there were clearance issues....and as noted they were corrected. The info I had came first hand from a manager at MM who helped build the first LT-5, even before the assembly line was in place.

That was very early in the program

The cam issue I am bringing up also due to some problems with regrinds, etc.....looking to have some done for the 90.

The problem with regrinds, in my opinion, are three-fold; (1) the base circle diameter has to be reduced to obtain more lift, (2) when the base circle diameter is reduced for more lift, the ramp angle increases and puts more torque on the camshaft x 8, and (3) the increased torque is ultimately focused at the weakest link in the camshaft, at the nose where the sprocket & vernier fit onto the camshaft. I've seen several cams with broken noses.

If I did not think the LT-5 was great, I would not own 3 motors...could easily go sell them and get a Z06...

LEE, YOU NEED A FEW MORE!
