Description of 1970 Chevrolet Camaro Z/28 Rally Sport Custom Green Interior

First I want to say that this is a super rare special car for so many reasons. 1970 Z/28s are rare in themselves, but this car's options make it so much rarer and such a car to be appreciated. But before we go there. Please visit this Youtube video so you can learn why the 1970 Camaro Z/28 is such a special car. Then, please come back and continue reading what I have to say about this paticular Z/28.

Ok, I hoped you watched the video. Now, on to the good stuff. This 1970 Z/28 RS Camaro is one of these sort of cars that I suspect with time 10-20 years, maybe less will be selling for six figure amounts. 1970 Z/28s have more than doubled in most cases in value in the last 10 years, and continue to appreciate. Now, many people do not realize that 1970 Camaros had the same high compression solid lifter 4-bolt main engine as the 1969 Camaro Z/28 even down to same 780cfm dual feed Holley carburetor, #186 large valve 2.02/1.600 high flow double hump heads, and GM # 3972110 high-rise Winter's aluminum intake manifold. There were a a couple differences although. One being 48 more cubic inch in 1970 and the GM # 3972110 intake while sharing the same part number had an unmachined oil filler boss in 1970. This was one year only GM # 3972110 intake made this way for 1970--the 1969 Z/28 had an expansion plug pressed in. See my photo of this part of the # 3972110 intake to get a picture vision of what I am describing. So, when looking at other 1970 Camaro Z/28s that claim to have the correct intake pay attention to this feature. I digress. Back to the 1969 Camaro Z/28. In 1969 there were 165,226 Camaros built while only 20,302 were Z/28s (12%). Its no wonder the Z/28s next to the ZL1 COPO cars is the most sought after 1969 Camaro. Now, lets look at the 1970 Camaro Z/28. Out of 124,901 1970 Camaros built only 8,733 were Z/28s (6%). It is rumored only around 10% of the 8,733 1970 Z/28s were double optioned split bumper Rally Sports, making the 1970 Z/28 RS cars super rare and desirable. But if you do some looking online or on the Mecum or Barret Jackson auction reports, and you can find a 1970 Z/28 RS split bumber car, you will find most have standard plain black interior, and/ or lack a center console, or are an Automatic car when most collector's prefer a Muncie pedal car, etc etc.
Ok, whats my point? How does this apply to the car I am selling? Well, not only is the 1970 I am selling here on Ebay a double option Z/28 RS, it has not plain black interior. It has dark green interior that includes carpet, dash pad, door panels, seats, head liner, seat belts, etc. And it is not just code 723 dark green "standard" interior, it has ultra rare code 724 "Custom" interior that included totally different seat covers than "standard interior", door panels and much more such as: deluxe seats and sidewall trim; glove compartment light and additional instrument cluster lighting; wood grained accents on instrument cluster, steering wheel and door trim panels; luggage compartment mat plus special engine compartment and interior insulation. This was a $115.90 option which was a lot of money in 1970 for something like an interior option. The Rally Sport option this car has was a $168.55 option in 1970 and included: special black painted grille with special rubber tipped vertical center bar and resilient body color grille frame; Independent LH and RH front bumpers replacing full width bumper; license plate bracket mounted below RH bumper; parking lights with bright accents mounted on grille panel; Hide-a-Way windshield wipers with black-chrome finished arms and articulated left hand blade; bright window, hood panel and body sill moldings; body colored insert on door handles; RS emblem on steering wheel; Rally Sport front fender nameplates; bright accented taillights and back-up lights. (RS emblems deleted with SS or Z28 option). This car also has other special options such as soft ray factory tinted glass, center console that was a $59.00 option in 1970 and not included with either the Z/28 or RS package, 4-speed manual Muncie M20 wide ratio transmission,sport mirrors with driver's telescopic remote mirror, and most unusual rear defog blower motor that us actually still present in the trunk of the car and operated by a switch on the dash panel.
I own SAG Performance Group which is a race engine shop. I did just do a major over haul on the engine in past three months including competition multi-angled valve job on our VGS-20 Sunnen head machine new severe duty stainless valves, new valve springs, new cam and lifters (broken in for 1 hour at 2500rpm with Lucus ZDPP zinc), all new gasket kit, major rebuild and tuning on holley carb w/ #7.5 power valve and jetting, etc etc. Pistons are .030 over TRW forged. Heads were flowed and ported and polished. Transmission was taken down to bare case and cleaned and any wore parts replaced, synchros checked, etc etc. New input shaft retainer was installed on Muncie, new forks, and more. Engine and transmission were just put back in the car in last few weeks! I also pulled the rear diff cover and flushed it and checked it out and verified it was 3.73 ratio Posi, I installed the posi limited slip additive along with new 80/90 dear oil and put new gasket on 12 bolt cover. Clutch was adjusted, throw-out bearing checked, flywheel surfaced, and lining checked. Distributor was rebuilt with new points and condenser, new AC delco wires, and plugs cleaned and gapped. Engine has been professionally tuned with 12 degrees idle timing so that it starts and shuts off easily, and does not over heat.
Yes, during engine work I did retain the factory 11.0:1 static compression ratio and the solid lifters. Yes, it does run just fine on premium pump gas. I have set the valve lash correctly and double checked it to ensure it is staying set and cam lobes are not going away. It would be plain wrong to detune this car. The only 2nd Gen Camaro (1970-1981) to ever have solid lifters, high compression,Holley 780 dual feed carb, #186 heads and #110 intake etc etc. This is a factory race car!
Factory gas gauge works, factory temp gauge works, factory tach works, new door pins and bushings were installed within last 6 months. This car appears to have some factory paint on underside of truck, in some places in jams, and in engine compartment along inner fenders but I did pay a lot of money to have the entire car repainted around 3 months ago! Back seats and all belts and door panels and cluster all appear to be original, but front seats have been correctly recovered (as good or better than factory) and new correct dark green loop carpet installed.
I think this is the kind of car a person can retire on one day. Its tempting to keep it and hold it considering what it is. However, I would like to pay off a commercial real estate loan so this is why I am offering it for sale.

This car has dated glass, dated sheet metal and dated gas tank 1970 (appears to be original gas tank). First car I have ever owned with dated gas tank. Tank is solid and does not leak and sender works as does gas gauge. This car I am highly certain has never had body off frame and received what appears to be a light coat of dealer installed undercoating on the under body of the car which protected it very well from rust and rot. There are many areas one can see what appears to be the GM factory "Zero Rust -red oxide" primer on the under body of this car under the light undercoating. Hence, survivor attribute.

INTERESTING FACTS PERTAINING TO ALL 1970 Z/28s as equipped by GM:

While 1970 is the 1st year of the Second Generation Camaro, it is also seen as the last of the high compression, solid-lifter cam, low geared ground pounding muscle cars. While the 1970 Camaro was being introduced, the muscle car market was disappearing, or at least changing. Among the other changes, highlights & distinguishing features for 1970 were....

  • Last year for 9+ compression engines
  • Only year 12 bolt rearend installed in performance 2nd gens
  • Variable ratio steering debut
  • Front disc brakes standard
  • COPO 9796 3 piece rear spoiler available
  • Only year a low-back style seat & headrest offered
  • Sunvisor was longer than other models
  • Only year a Chrome "C" used on header panel
  • Only year a "Camaro by Chevrolet" emblem used on trunk
  • Only year side marker lights didn't blink with signals
  • Only year ever to have solid lifters and 11.0:1 compression ratio in any second generation Camaro
  • LT1 Rated by NHRA at a true 425 horsepower in 1970 (GM was fudging the numbers for insurance purposes).

The "Z28 Special Performance Package" (RPO Z28) was not only positioned as the top Camaro performer, but it put its money where its mouth was. Designed to race in the SCCA Trans Am Series, the 1970 rules changes allowing for the 5.7L engine meant the Camaro was able to now use the 350 engine. The previous Z28's were limited to 302 cubic inches and were known to be tempermental on the street. The bigger engine also allowed an automatic transmission to be used in the Z28 for the 1st time. Due to the solid lifter, high revving cam, Air Conditioning was still not available on the Z28. With a stout drivetrain, including a mandatory 12 bolt rear axle, and a tuned suspension, the Z28 was a match for anything found on the street, or at the track.
RPO Z28 specifically included in 1970: One-piece low-profile rear spoiler standard; 3-piece high spoiler (COPO 9796) available optionally after Apr. 20, 1970; special instrumentation; dual exhaust; black painted grille; Z28 emblems on grille, front fenders and rear deck lid; rear bumper guards; special hood insulation; special paint stripes on hood and rear deck. Special 350 CID, 360-bhp V-8 derived from Corvette LT-1. Four-bolt mains, forged steel crank, TRW impact extruded pistons, 11:1 c.r. Standard cam was 1969 optional cam, with 317-degree intake duration and 346-degree exhaust. Lift: 0.458 inches intake and exhaust, Carburetion by Holley 780-cfm (4150) 4-barrel atop new high-rise aluminum manifold. Spark via aluminum single-point, vacuum controlled distributor. High-performance oil pump, baffled pan, windage tray. Cast aluminum rocker covers with internal galleries. Twin-pulley fan drive. Mechanical valve lifters. Same heads and valve sizes as 302. Chrome dressup kit, larger-capacity radiator.

Transmission: Mandatory choice of same Muncie 4-speeds as before, with special 2400-rpm-stall torque converter Turbo Hydra-Matic optional. First year an automatic transmission could be ordered in the Z-28.

Clutch: New 11-inch unit.

Rear Axle: GM 12 bolt (only year 12 bolt used). Positraction optional. 3.73:1 ratio standard. 4.10 ratio available (RPO ZQ9).

Brakes: 11-inch, vented, cast-iron front discs with vacuum assist standard. Rear 9.5-inch drums.

Front Suspension: Similar to previous Camaro's. Z-28 anti-roll bar 1.0-inch diameter instead of standard 0.6875-inch unit.
Rear Suspension: RPO F-41 special suspension standard, including 5-leaf rear springs, 125 lb./in. spring rate, staggered heavy-duty shocks, link-type rear stabilizer bar.
Steering: Standard non-power steering ratio 18.8:1 or 4.1 turns lock to lock. Optional power steering came as variable-ratio at 14.3-10.9:1 for 2.3 turns lock to lock.

Wheels & Tires: 15 x 7 steel wheels painted dull grey with bright lugnuts, center caps with blue bow-tie and trim rings,
Wheel Code: AU, Part #: 3983045, Center cap part #: 3989479, Trim Ring part #: 3984524.
F60-15 fiberglass-belted white letter tires standard.


*While this car has many attributes that appear to be "original". I guarantee nothing about this car whether it be options or parts on the car to be "original" and/or "born" to the car. I did not buy the car new and only represent the car as it is now here in 2018. Over the decades many parts get taken on and off these cars during repair and or restoration or modification. What I have stated about the survivor attributes of this car are only my opinion from observations made looking over this car. I have owned numbers matching collector cars over the years and have consulted with many experts such as Jerry Mcneish, Dale Macintosh, and others on these cars. So, you can take what I am saying to be sincere and in good faith about this car, but again, I guarantee nothing "original or "born" to this car, only that is is a very correct and original appearing car based off the assessments made and information I have been provided. The dash/ cluster, headliner, door panels, back seats, etc etc appear to be original but I cannot guarantee this since I did not buy the car new--but personally I am highly certain--when you spend enough time around these cars and own enough of them--you can just tell certain things by the patina. Windshield has been replaced and is not GM LOF dated, but does have antenna in glass as soft ray would have.
