Glad to see this thread is still alive.
FWIW, the yellow 911 V8 seen at the beginning of the thread is about to come back from the dark side. Keith is installing a highly modified 911 motor into his 911 so that he can go PCA racing (GT3)
.
Personally, I am very glad to see this. On the track, I could not pass him with the 3.2 914-6 vs his 500HP+ V8 911.
