Hi Everyone, I am a new Z owner :classic: . I bough this car about three weeks ago. The car was built up two owners ago. The PO, who I purchased the car from had very little information about the cars'specs and could not locate the owner before him. http://home.comcast.net/~jheng/index.html I am hoping to locate the enigine builder to get a better idea of what I have. I beleive the engine builder lived in Santa Rosa, CA. I am not new to but it was many many years ago and a lot of beers consumed since I've owned one. I have determined a lot about the car from resources such as this site, but much still remains a mystery. Its kind of like Christmas, I keep discovery new neat things about the the car, but new questions keep arising. You will probably see more post from me in the near future about some of these things. What I do know is the car has a E88 head with L28 block and 44mm? Mikuni's. Thanks Jeff
