brand new motor 1100 miles or so on it, 90% highway, never seen life above 6,000 RPM unless the tuner did so...

it lasted one day after i got it back from the tuner. at idle it would lose oil pressure, changed oil and filter, it came back 50 miles later, cut my filter open found lots of copper.
looks like the bottom end was not well put together by my builder. oil pressure is 11PSI at idle, and drops as the motor warms up 70psi at 4,000rpm. looks like this motor is coming out and time to rebuild the bottom end myself. hopefully no crank, rod, or block damage.

 

I hope that was warrantied . . .

 

at this point, i dont trust the original builder to fix it, i am just going to do it myself.

 

I'd at least press him to pay for parts for you to do it. That's absolutely unacceptable. You paid for a built engine that essentially fell apart during the test drive. I agree with not trusting him/them, but they're still responsible.

But I know how you feel, to an extent. My shop almost killed me by not tightening my lug nuts after a tire rotation, bunch fell off. They turned a spark plug change and 1 coil replacement into a $900 repair, and improperly installed locking bolts ($6 a piece) on my long tube headers and broke a bunch of them.

 

I had the same problem too. I shot to 125 and found out that the aluminum stocker couldn't take the centrifugal force. Went to a driveline specialties 2 piece 120 steel with support bearing and once set up No more issues.
