Glen Posted September 3, 2022 Share Posted September 3, 2022 Not quite sure why this guy insists on re-badging the air cleaner it when it was originally sold/marketed as a 402, but I wonder if it’s authentic. I’m not a First Gen cyclopedia by any means, so maybe I’m missing something? The ad says he has a build sheet, yet I didn’t see that in any of the pictures… Perhaps an email to the seller is in order. And while it’s not too close to me, it’s not terribly far… I’d be happy to take a ride for pictures and numbers verification, etc. if anybody is genuinely interested. And this might be fate or serendipity or whatever… but the sellers name is ALSO Rob(b), Mr. Peters. https://chicago.craigslist.org/nch/ctd/d/kenilworth-1970-chevrolet-monte-carlo/7528116764.html Quote Link to comment Share on other sites More sharing options...
MarchieB Posted September 3, 2022 Share Posted September 3, 2022 I'm not sure if any Monte Carlos came from factory with any stickers on the top of the air cleaners. Also it would have been marketed as, and is technically a LS3 - 400 Turbo Jet. The 402 moniker is only a nickname given to the engine referring to it's actual 402.2 CI displacement. So the correct sticker (if any) would have been "400 Turbo Jet" There is full documentation on the site where it's being auctioned (at the end of the craigslist ad) https://www.clasiq.com/auction/1970-chevrolet-monte-carlo/ and it appears to be a genuine factory '70 400 - 4 speed Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted September 3, 2022 Share Posted September 3, 2022 All Monte Carlos 70-71, small and big block had cubic inch and hp rating stickers on their air cleaners. The blue one is of my brothers 71 SS454 and the red one is "Big Red" my 70 SS454. Neither air cleaner is correct for the cars. The one on the blue Monte is actually a fairly uncommon dual snorkel one from a 70 bb Chevelle and the one on Big Red is an aftermarket one for a bb Camaro that fits a Holley carb. The 71 now has the correct 454 air cleaner assy on it. Quote Link to comment Share on other sites More sharing options...
Glen Posted September 3, 2022 Author Share Posted September 3, 2022 Oops. I didn’t realize that someone else mentioned this car in a thread yesterday. Quote Link to comment Share on other sites More sharing options...
714024SPEED Posted September 3, 2022 Share Posted September 3, 2022 1972 did not come with air cleaner cubic inch and hp rating stickers. GM changed the way they rated HP in 72 so supposedly it was bad for appearance and marketing to put the new lower HP rating. 2 Quote Link to comment Share on other sites More sharing options...
TheBMan Posted September 4, 2022 Share Posted September 4, 2022 Unless I'm missing something, the 402 big block cars were labeled as 400, not 396. Regardless, this guy says "This is the original 402 cubic inch V8 that Chevy marketed in 1970 as a 396", which I'm pretty sure is not factual (at least in the case of the Monte Carlo). Looking at this resource page seems to confirm this. I'm genuinely interested in @Rob Peters feedback. I agree with @Glen, I'd like to see the build sheet.

MC1of80 Posted September 5, 2022 Share Posted September 5, 2022 In 70 all 396's we're actually 402s. They kept the 396 call out for the Chevelle's and Camaros because the SS396 sold so well. Why mess with it. You could get a 402 in a non SS Chevelle and those cars had a 400 emblem towards the front of the fenders by the headlights. If a 400 emblem behind the front wheel, it's a small block 400. This emblem location/meaning goes for the impala also. The Monte Carlo is a 402 and was advertised as such. Not a 396. Also the big block 400 were actually 402s were also known as "turbo jet" while the 400 "ram Jet " was a small block. Note- the small blocks are known as "turbo-fire" thanks again sbarnette. 2 Quote Link to comment Share on other sites More sharing options...

MC1of80 Posted September 5, 2022 Share Posted September 5, 2022 Morning all. Sbarnette, you are correct. The small blocks are "turbo-fire". Thanks for catching me on that. 😁 2 Quote Link to comment Share on other sites More sharing options...

TheBMan Posted September 5, 2022 Share Posted September 5, 2022 @Dtret @MC1of80 So what would the decal on the air cleaner be? Would it say 402? I found this but it's not from a Monte Carlo, it's from a 1970 Chevelle. I can't find an image of a 1970 Monte Carlo 402 engine bay. Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted September 5, 2022 Share Posted September 5, 2022 Yes. Like that for a 70. 1 Quote Link to comment Share on other sites More sharing options...
