Kurt,
Thanks for the welcome! I've been hanging around CRG for a couple of years and have learned a lot about my car as a result.
As a result of the thread on cowl induction hoods, I was able to verify that my Z originally came with the cowl hood. It was on the car when i bought it but had no wiring, solenoid, relay or frame on the back of the hood. I dug out the parts I got with the car recently and found the door(knew I had that), solenoid, relay, and grommet for the hood. Other items that came with the car is the backdrive linkage and some shifter rods(Car has a aftermarket Hurst shifter in it), chrome exhaust tips from the original exhaust, NOS door and roofrail weatherstrips, and a few other miscellaneous items.
I still need to document some other things like the bell housing, flywheel, starter, etc but after I do that I'd like to post what I've found if that is OK.
Is it fairly common to be able to only see a few of the VIN numbers on the rough casting of the block? I have no doubt now that it is the original engine based on the car build date and the casting date of the block.
Thanks,
Larry
