Already called him on a couple of mistakes, he is a blow hard and sadly
represent some of the owners that like to spend money and brag about it and
owning a Corvette. He does have knowledge I don't but if you call him out he
just hides and don't reply like he didn't even notice what was said.

Myself I like to know what I'm driving and what it can do but could care
less what someone else drives and see no reason to cut them down for their
choice. Which brings me to your statement that the "C7 wouldn't get out of
the shop". What does that mean except you would like to knock something you
know nothing about. I haven't seen or heard of any "cam destroying spring
pressure" from any cars for decades. Ever hear of roller rockers? Back in
the 70's when GM built the V8s with the hot centers there were lots of cam
failures but it was not from spring pressure it was carbon ash that ground
down the lobes.

My oldest son drives a Toy pickup and he couldn't get close to the mileage I
did on my Chevy van that was 800 pounds heavier. His Odyssey is about 5 MPG
short also. Poor old push rod V6 just never knew when to stop on a tank of
gas. When I had the Northstar in my STS it soured me on the overhead cam
with it's bad gas mileage. The DOHC I have now is about 6 mile per gallon
short of my C6 but it does burn regular.

By the way he lives about 20 miles from the BMW plant/museum in Greer S.C.
and if you ever get there it is a treat to see. If possible take the plant
tour, sporadic availability but worth the time if it works out.
