1970 Chevy Yenko Deuce Nova Citrus Green

1970 Chevy Yenko Deuce

The 1970 Chevy Yenko Deuce Nova was a tamer version of the wild 1969 Yenko Nova with the COPO 427 engine. Even though it still produced 360 horsepower, insurance companies treated it as if it were a regular small block 350 Chevrolet engine. That it was not. Off the showroom floor they figure it would do low 13’s.

Don Yenko was very good at manipulating Chevrolet’s Central Office Production Order (COPO) program, first starting with modifying Corvairs at his Chevrolet dealership in Canonsburg, PA. Eventually he moved into muscle cars where the fun really began! What made Yenko famous was developing the reputation as the dealership that could put a 427 ci big block motor in a Camaro set up for a 396 from the factory. In 1969 he exploited the COPO program at Chevrolet to have them made from the factory. Later he would use the same COPO system to produce his 1970 Chevy Yenko Deuce Nova, such as the one you see posted here.

This 1970 Chevy Yenko Deuce is one of only 50 built by Hurst at Yenko’s request. The cars were ordered as COPO cars using Chevrolet’s fleet buying program.  Under the hood of the 1970 Chevy Yenko Deuce Nova you will find a 350 cubic inch LT1 producing 360 horsepower. Backing the small block V8 with solid lifter cam was a Muncie M-21 4-speed transmission, 12-bolt rear end, 4.10 gears, positraction, front and rear sway bars, and F-41 suspension. There were eight exterior colors which these cars could be ordered in. They say a total of 177 cars were ordered with COPO 9010. Yenko ordered 175 of these and two went to Canada. Of the 175 Yenko versions there were 122 that were M-21 Muncie 4-speeds. The remaining 53 came with the TH400 automatic transmissions.

The 1970 Chevy Yenko Deuce Nova you see pictured here is No. 160 out of the 175 Yenko Novas ordered as a COPO from Chevrolet. There were only 10 such cars that came with painted Citrus Green from the factory. Of those, only one came with a 4-speed and power steering. This is that car. It is being sold by Nickey Chicago, the muscle car dealer with the legendary name. They have traced the car back to the 1980’s when Jerry Janota purchased the car from what we believe were the second owners.  “Based on the history of the car and Jerry’s verification that he bought the car with the original drivetrain, we believe the car to have the original, engine, original trans as well as original rear end housing,” they told us. Janota has provided an affidavit verifying what he has told them. Janota believes it was originally sold at Sam Leman Chevrolet in Roanoke, Illinois.

This car was restored frame off by Bob Joyce about 10 years ago. In 2005 it was driven in the Hot Rod Power Tour from Milwaukee, Wisconsin to Kissimmee, Florida. It still has the Long Hauler window sticker.

Then the Deuce was completely frame-off restored in 2015 by MASCAR, Detroit Muscle restorations in California. The restoration  included a fresh rebuild of the drivetrain. The Deuce was debuted at MCACN VII where it was awarded Concours Gold.

 The Yenko Novas were all modified at Hurst Performance, then sold as Yenko Deuce Novas at Chevrolet dealerships all over the U.S.  Each Yenko Deuce featured a front bench seat and standard-grade black interior. The COPOs came with Rally wheels with no trim rings. The Yenko versions changed them out for Magnum 500 wheels. There was a Yenko emblem on each centercap.  Yenko’s shop used distinctive vinyl die-cut graphics as his Yenko signature.  All 175 Deuces had a domed tachometer on the driver-side hood,  an AM radio, black rubber floor covering, power front disc brakes with drums in the rear, floor mounted Hurst shifter, and a special interior lighting group.  Yenko went with the smaller 350 engine found in the ’70 Camaro Z/28s to stay under the radar of the insurance companies. Yenkos were said to do low 13’s with slicks.
This was the last year that the Nova was associated with high horsepower performance. It was the only year that the Chevrolet Nova would compete in Trans Am racing.

    In 1975 for $1,500 I bought what I thought (then) was a 1970 Nova SS black/black; I was 17 starting my senior year…and Fall harvesting was about ready to begin.

    It was an unusual car…and I’ve never seen another like it before or since. It had a very nice (slick) black paint job…it had one tell tale sign on the passenger side inner fender of it’s original (citrus green) paint (weird color I thought). I was glad for the black repaint…it looked good…understated beauty w/ no exterior SS badges or the faux hood fins. The car screamed when you put your foot in it…serious rubber in all 4 gears…and that sweet (exhaust) back blast between shifts when you’re just revving up and easing thru the gears; nothing sounds quite like it!

    The car’s compliment’s included: LT-1 engine (I recognized it because my brother had a 71 LT-1 Corvette) solid lifter cam/LT-1 dual plane (GM) alum high-rise intake/780 Holley dual feed carb/fuelie double hump heads w/ARP rocker studs/alum finned LT-1 valve covers/Mallory coil & DP Dist/Hedman LT headers/Thrush mufflers w/side exhaust; shatter proof bell housing (thank God – I exploded my 2nd clutch a couple months later after pulling the front wheels on Main St at midnight on my way home after work); 11″ HD Clutch; Muncie M-21 w/ Hurst stamped (long throw) Competition Plus shifter w/T handle; drive shaft safety loop; black (very plain) rubber floor covering and bench seat (kinda weird I thought but great on dates); 8k SW steering column mounted tach; SS steering wheel; SW 3 gauge pack under dash; AM Radio & 8-track tape (previous owner added for tunes); No AC; power assist front disk brakes; sway bar front & back; 12 bolt posi w/ 4:10; lakewood traction bars; Monroe air shocks; 69 Z28 style deck spoiler; bright accent interior – around the pedals; black vinyl top w/ polished window accent/side accent molding/and chrome driver side mirror; E70X14 front and G60X14 rear on Cragar SS Mags; and a spare F60 on slotted gray GM wheel.

    I sold the car a couple of years later (77) when I was in the USAF…to a friend in my unit; A1C Gregg Lacey. I heard later that Gregg had sold the car to a guy in Logansport, IN.

    I miss this car a lot these days…it was awesome looking…and a pure adrenaline rush to drive. Stupid kid I was…I didn’t get any pictures of this car…and never kept any of the car’s documentation (VIN and such). I know…kick me!
