Neat..notice the makers mark in the rear lift bkt.
My god..look how brilliant your RFI shield is. Does it still have the instructional label inside? https://www.yenko.net/attachments/386674-tn_016.JPG |
Re: really cool 70 Z28..simply the best.
Cool stuff, please keep the pictures coming.

Re: really cool 70 Z28..simply the best.
Has the car been driven since it's purchase??Are you going to try & start the car soon? Or do you think it needs to be torn down & gone through????
|
Re: really cool 70 Z28..simply the best.
Does it look as though the base of the dist or intake manifold have any silver overspray, like would have come from spraying the hold down and bolt with them installed?
What about around where the lift hooks mate up? |

Re: really cool 70 Z28..simply the best.
Silver paint is from the touch up from the Orange overspray, I understand they had a guy at the end of the paint line touching up the intake with silver paint.
Most of my intake bolts have silver on them also. Keep up the Great work Charlie!! |

Re: really cool 70 Z28..simply the best.
Charley,
Does the car have a "CHART-ADAPTER ASM" ?? It attaches to the end of the speedo cable at the trans and makes a 90 deg turn. The speedo cable screws on one end and and the other end screws to the trans. Thanks https://www.yenko.net/ubbthreads/imag...lins/beers.gif |

Rick, I have seen that list in Colvin's book and questioned it. It doesn't make sense to waste paint on a motor that might fail at test. Not to mention, it would make small leaks hard to detect.

Does John know if they used what looks like #2 Permatex during assembly ? It looks like it on head bolts and screw in studs ? [/ QUOTE ] Yes - they used thread sealant on head bolts and on the screw-in stud threads; both protruded into the water jackets. https://www.yenko.net/ubbthreads/imag...lins/beers.gif |

Thanks, -Sam [/ QUOTE ] There would be no paint on the hood hinges or springs; they were phosphated, and were attached to the fender long after paint, right after the front clip was bolted to the body. https://www.yenko.net/ubbthreads/imag...lins/beers.gif |
Re: really cool 70 Z28..simply the best.
Thanks for the input John.

Re: really cool 70 Z28..simply the best.
Great info John...Thank You.

Re: really cool 70 Z28..simply the best.
John,
Thank you for correcting me on the wax info. My friend who was an engineer at Lansing Assembly informed me of the Micro-Poise material after I had put down my information. Thanks again for correcting me!! https://www.yenko.net/ubbthreads/imag...iggthumpup.gif |
Re: really cool 70 Z28..simply the best.
Hey Charley,
I'm probably the only one who hasn't congratulated you on your awesome acquisition yet, so way to go!!! (Yes, I'm as jealous as all the rest too).... Now that I've done some brown-nosing, may I be included in the list of people who seek historical info from your cool ride (or from anyone else who has this info available)? I'm sure you have absolutely nothing else to do... My question relates to the RS endura nose. I just painted my 73 RS Z and was wondering what finish would be correct for the mounting brackets/tabs inside of the RS nose before installation? My nose piece (both the rubber and metal sections) was black primer prior to painting, and I purposely let the silver paint fog on to the mounting brackets. Should they have been bare metal (taped off from the factory?)? Primered? Painted body color? Blacked out after body paint? Any suggestions from you guys??? Thanks in advance!!! Charlie |

Re: really cool 70 Z28..simply the best.
JohnZ,
Thanks for the information on the hinges, and Charley thanks for posting the picture of that baby blue inspection mark! https://www.yenko.net/ubbthreads/imag...lins/beers.gif -Sam |
