im only 28 and i LOVE quiet/sleeper cars...

ive been watching your thread on ls1tech, the swap is awesome!

Thanks for the compliment!

This morning I took the GMAT test and my brain was sizzled.

I got a replacement alternator in the mail today. I have to admit that the partsamerica.com exchange system works quickly and effortlessly. I just hope this alternator will last more than a few days. After installing it I drove around town and put about 50 miles on the car. The alternator seems fine and the car runs strong. I got on it a few times and it certainly feels as strong as the big block did, although the lack of torque is noticeable in second gear. I used to be able to break the tires loose from a roll in second. No more. That's not surprising and I am sure that the drag strip times will not be disappointing. This engine pulls like a freight train above 3000 RPM.

I also noticed that it is running fairly rich at WOT. My wideband was showing a steady 11.9:1. That is not surprising since I am using the LS7 tune up. Once the engine is broken in some more I will take it to my local tuner and tweak a little bit. There is no black smoke and no drivability issues at all. I should pull a plug.



On the highway there is still a little vibration above 80MPH. Before doing anything drastic I am going to double check the wheels and tires as well as the driveshaft. Since the car sat for a while it is entirely possible that the tires have developed some flat spots and that will certainly be felt at high speed.
