Looks like a nice car. I wonder if it retains its original paint ?

That is nice. If I didn't own a 70 Z28, I'd be interested. I'd be asking if he still has the AIR Smog system and the chrome shifter knob. Wonder why there are no pics of the underneath showing the exhaust at least and the front and rear sway bars. I guess you can ask for them if your interested.

I asked about documentation and the seller said that the car did not come with a build sheet and this is normal for Nor built cars, is that accurate? There was no mention of any paperwork at all e.g. POP, etc. and given it's ownership history-seller states that it was bought from original owner-wouldn't you think some of that should have been available?

I also thought it was unusual that there weren't any undercarraige or engine stamp pics, considering that the car's history (umpteen shots of the exterior and not much else). Seller said that he would take some and post them in the ad. We'll see.

Your correct, Norwood cars build sheets went into the trash unless you were lucky. The original owner should have paperwork and especially the POP. When I got mine in '81, the owner had the POP and gave it to me along with all the bills he had.

The car looks like one from Cal that I was interested in back in 1980 and had pics mailed to me.

I too am suspect of a car advertised the way it is with only one measly interior shot, no under body shots (exception being the weak shot of the 12 bolt), weak engine shots and no shots of numbers. The seller could just be naive about the tranny being an actual M-20 since the car should receive the M-21 from the factory but coupled with the stamped VIN discrepancy I think it suspect. A lot of questions to be answered before I would place a bid especially at the price point.

not verifying any of his claims and i know nothing of the car but ...all the info i have shows the 1970 - 72 Z28 could be ordered with any of the 3 muncies ?? i believe the trans HAD to be specified when ordered. there was no standard trans that automatically came with the Z28 option . you , or the factory on a spec car , had to choose 1 of the 4

Thanks for all the good input. It looks like a nice car but the info seems a little vague. I'll keep working on it.

I think Chevy's internal protocol kicked in with rear gear ratios...3.73:1 should have required an M-21 from the factory - especially in Z/28. When you say choose one of the 4 what do you mean? I count only three 4-speeds available for Z or any other performance option (read SS small or big block). Are you counting TH400 in there?

I just realized you are in Encinitas...I'm in Unincorporated Vista. Small world

Yeah, just down the road. I am sure that we have crossed paths somewhere-maybe Escondido cruise night? I'd love to see your 70 Z sometime. I have been looking for one for a while but finding a good unmolested one is tough. I have a 69Z but would love to have a second gen too.

LOL - my '70 is in pieces. I did Escondido once years ago. It depressed me to see whole lots full of PT losers. The actual cruising was not happening so walking around was the only option and there was no where to park our car nearby (in part because of the PT losers). We don't ever go.

well you had to chose from 1 of the 4 trans options ( auto included ) . you couldn't get a rear ratio lower than a 373 in a 70 Z28 so im not realy sure what you mean by that . the m20 373 could even be had in 73 and 4 ( as long as you didn't have A/C ) the m20 342 was a forced A/C rear on the z in 73 and 4 . i thought there were members on the site with a M20 70 z . i mean all the literature states 4 speed manual or auto . are you familiar with the gm heritage site ? i mean , it looks legit and it states the m20 could be had in the 1970 z28 even with a optional 4.10 gear. i cant copy the page as it copy written or my java script wouldn't let me . here is a link to the site , its easy to follow . http://gmheritagecenter.com/gm-herit...tion-kits.html . not trying to be a PITA , but i thought you could get a M20 on a 70 - 73 Z28 ??? i cant see any reason why not . and there was no forced or standard trans for an year Z , except in 73 when you ordered A/C it forced the M20 342 combo

My 70 Z28 is a M20 car with GM Canada paperwork.

You could get a 4.10 ratio from the factory. It was the only optional rear available for 1970. All the others ratios could be ordered through the parts Dept., but would have to be dealer installed.
