Thank You Henry, JRV, and John!
I drove the car today too....we had another rare spell of nice weather...and I'm taking advantage of it. I have never been so happy with any vehicle I've ever owned before...she runs so good! I feel so fortunate. I still haven't figured out why, but after the car is warmed up and I stop and shut if off...say to pump some gas...and then hit the road again...for about a minute this car just runs like stink. It's wierd and amazing at the same time. I wish it would do this all the time! The acceleration is really impressive, close to my old ZR-1 that easily ran low 12 second quarter mile times. After the magic 1 minute window it still pulls hard but not brutally so.
John...the engine is actually totally detailed with all new nuts and bolts, etc. My gripe was that most of the work is hidden, and your observation supports this fact. I'll post a pic of the completed engine so you can judge for yourself. The motor looked better out of the car! Oh well...what ya gonna do? It does seem to impress people when I open the bonnet.
