ONLY if it had an engine code for a 454 on the protect-o-plate. The SS package was manditory with the 454, but you could get most all other V-8 engines without the SS.
no... in 71 you could get a SS 454 SS 350-4 and SS 350-2
70 was the last year for what you are explaining.

I think you misinterpreted what Dave said, Brian
Seems to me he said, If the 454 engine code is on the POP, it has to be an SS
IF any other engine code is on the POP it may or may not be an SS.

...plus the 402 with or without the SS option.
you're right i was reading the responce to the question at a statement, not a responce. thanks for clearing that up.
oh yeah that 402, forgot about that on the 71, see most of those on 72's

Actually even though there were more LS3s sold in 72 (20,031) vs. 71 (17,656) there were more possible cars it could be installed in, 605289 in 72 and 493418 in 71. Percentage-wise the LS3 was a bigger seller in 71 (3.58%) than 72 (3.31%). Just yanking your chain...

Yes, the LS3 could be ordered in any series/body style from 70-72 and is a big block. It was often called a 400 Turbo Jet. The LF6 was the 400 cid small block (400 Turbo Fire I believe) but it wasn't available in the Chevelle. It was available in the 70 Monte Carlo but relegated to the full size car line in 71 & 72.

Dale, where did you get the exact numbers on 402 blocks installed in 71 Chevelles? I've often wondered how that was broken down. Wasn't there a total of 24,000 and change SS cars in 71 total? Do you know how they are all broken down by engine?

Quite a number of years ago a gentleman named Len Williamson got into GMs records and compiled data (that was available) on all the Chevrolet models from something like 1953 to 1987 and 'published' a book called "Tailfins & Bowties". A member here has one and generously let borrow it for a few weeks to get the 1964 to 1972 Chevelle data and I managed to squeeze in some 73 thru 77 stuff as well. Had I more time, I'd have scanned more of it.
Anyway, it lists (from 64 to 70 at least) the total number of reported RPO sales, costs, and what series Chevelle it was available with. In the 71 & 72 data it does not list the series availability, only Chevelle as a whole.
What's amazing is the entire book (overflows a 3" looseleaf binder) is hand typed on both sides of a page!
I have found a few areas where numbers do not match up and some option names wrong (IMO), like the 71 Z15 option being listed as Z15 SS 454 when, in fact, the 454 had nothing to do with the Z15 option in 71, 72 is correctly listed as simply Z15 SS EQUIP. Total Z15 options for 1971 was 19,293 and 1972 saw 24,946. Since the Z15 option could include either 350 engine, the 402 engine, or the LS5 and both 350 engines and the 402 could be ordered without the SS option, you can see how it'd be a SWAG to determine the number of SS optioned Chevelles with either of those three engines. The 454 is easy since there are a known number of LS5 options sold (9,502 in 1971 and 5,333 in 1972) and the LS5 454 required the SS option.As noted with the accompaning explanation with Dan Carr's poster and stated again on the Camaro Research Group site, and to quote CRG
Dan gets into the exact procedure he used to come up with the numbers on the poster but it's more involved and CRG's is easier to grasp. BTW, if you haven't seen Dan's poster, it's big and beautiful! Just be sure to read the documentation that comes with it.
wow, amazing amount of info thats out there. I really hope to find a build sheet in my car. the frontal area of the car has been searched. The rear carpet and seat have now been checked. there is nothing about the car that has told me its not an SS.

Aside from the probable badging, what leads you to believe it is an SS? Does it have a domed hood (not cowl induction particularly) w/pins, remote LH mirror, round speedometer/fuel gauge, etc.? Are the dash knobs plain or do they have the function symbols on them?
These items can easily be added to a Malibu (not that that's a bad thing), but just curious.

It has ss badges not ss454. it has a cowl hood w/pins, not cowl induction.
It has a glove box light. it has boxed lower arms in the rear. it has speakers in the dash and in the rear.
It has a small block steering shaft and radiator (SS 350-4). the car now has a tremec but when i pulled the 700r there was a hole in the floor that was patched with a rivited pice of alum.
The auto brake pedal was new looking compared to the ebrake pedal and the gas pedal. The hole where the clutch rod goes through the firewall was not there but the bracket that holds the steering column on the left was new and the bracket on the right was old.
The car had all the connections for AC and the controls in the dash, just all the under hood stuff for the AC was gone.
The dash is SS with idiot lights, fuel on the left speed in the center, and a clock delete on the right.
The paint code on the cowl tag is 19 19 and the car is all black no stripes, all black interior.
I have not found one thing on the car that tells me no. thats why i learn towards SS
I don't know for sure and that what i tell everyone, but i'd love to find out for sure. I have not checked the codes on the block, or the rear end. I have the cowl tag avail. if you wanted to take a look.
the car came with some extra gears in the 3.73 rear gears box that the guy said were the originals. When i bought the car i didnt know anything about these cars. I never asked the guy any details that i would love to ask him now. I was 17 at the time and wanted a "muscle car", now im 21 and i want to clearn about my Classic.
I should try and give the number a call and talk to him.

Positive sign.
Glove box lamp and speakers isn't relevant, boxed lower arms may be - not that up on later SS cars.
Positive sign with the round instruments and warning lamps but clock was an option, no such thing as clock delete.
Certainly some good indications. Nothing that couldn't have been added, and has been done to probably thousands of 70-72 Chevelles such as hood and dash.
If it's a small block as indicated, while it may match the VIN it won't indicate yer or no the car itself was born with the SS option. I am a 'collector' of trim tags and data as you may gather from my site. The trim tag won't indicate yes/no either but a photo for Chevellestuff.com would be welcomed. I know they're hard to photograph due to the location but if you get one, great.
Original gearset would be either 2.73 or 3.31, a stamping on the rear end housing would indicate which. I'd call the original owner and ask him if they have any paperwork showing the SS option (RPO Z15) was ordered. You are fortunate in this day and age to have relatively easy access to informaton your car. And it's always nice the next generation keeping these older cars alive. Kudos to you :thumbsup:
You didn't mention anything about the dash knobs or whether it has a LS remote mirror.
Which dash knobs do you mean? I don't have a stock radio, all i can think of off the top of my head is the head lights, wiper, and the cigarette lighter. I do not have a power LH mirror, and i don't have a RH mirror at all.
I have already submitted my cowl tag info to your website. i did it a while back. I could try and take a picture for you, it's in good shape.
I am amazed by the info for the car that is available. I appriciate all the hard work and TIME TIME TIME to collect and archive all the data. Truely greatful.
I have not checked behind the door panels. I've checked under the dash, under the front carpet and under the tar paper. I have not checked further than the front seats. a buld sheet could be in the doors, behind the rear seat or in it, or somewhere under the tar paper in the back.
My car is a arlington car, and ive heard alot of build sheets for 71 out of there are under the tar paper. I have not had a reason to pull the door panels, or the rear carpet or seat so thats why i havent checked.
I drive the car as much as possible so, i'd rather not tear apart that part of the car unless there is a need to.
I'm going to try and call the guy i bought it from today.
hopefully he still lives at the same place and has the same number. It's been about 5 years.

Yes, the headlamp and cigarette lighter knobs - wiper switch is a slide bar. Do they have a visual indication of what they do? I've seen lighter knobs in non-SS cars with the 'flame' on them (more than likely aftermarket parts store replacements) but haven't seen a headlamp switch knob with the 'lamp' on non-SS 71s.
Not power mirror, remote-control cable operated with the little knob on the door so you don't have to roll down the window. LH remote mirror was an option on Chevelles (D33) but came as part of the SS option so any 71 SS should have one. RH mirrors were not a factory option.
Appreciate it.
That's what we're here for.
