For Sale: 1970 Chevrolet Chevelle
LS6 M22 12 Bolt 4.10
I am the former owner/operator of Southwest Automotive and Car Pros of the Desert, which were both in Cathedral City and Palm Springs, CA and the current owner/operator of Texas Attitude Racing. I have built custom cars, drag cars, pro-street cars and have performed complete restorations on classic muscle cars for more than 35 years. I perform every task from wiring to engine/trans/rearend building and had built my first engine back when I was 14 years old back in 1977. For decades, I have been called up by many to either rebuild, modify, or restore cars, give values on cars or to verify numbers matching situations.
From 1/2011-8/2012, I had the pleasure to work on this 1970 Chevelle SS454 LS6 car for Marv. I removed the power plant, drivetrain and interior, performed a verification process, made upgrades on and in the car and reassembled the car. While performing this rebuilding process I was able to verify all numbers needed to come to my conclusion that this car is in fact a true LS6 Chevelle. I saw no signs of tampering with the VIN and/or Cowl tag, casting or stamped numbers on any item in this vehicle. The factory rose rivets are there and not tampered with on the VIN plate mount. This car appears to be an original 50,173 vehicle due to the condition of all the hidden and underneath areas and not a restored vehicle. The VIN# breakdown is as follows: 1 : Chevrolet Division 36: Malibu Custom 8cylinder 37: 2 door hardtop R : Arlington, Texas Plant The Cowl Tag reads as follows: 70-13637: which translates to 1970 2 door sports coupe which had the SS396/SS 454 options available to this code interior 75-75: Cranberry Red paint 04A: Built 1st week in April 1970
In my research and experience, I have read that, “1970 was the first year that the Super Sport became an option within the Malibu line, and also in a limited number of 300 Deluxe coupes, instead of a stand alone model. Therefore, it is impossible to document a 1970 Super Sport by the VIN number. There are 13 positions on the VIN plate. 1) will always be 1 signifying Chevrolet division of GM. 2&3) Series code-36 denotes Malibu eight cylinder, however there were a handful of 34 code base Chevelles also built with the SS option (without proven documentation, be wary of these.) 4&5) Body Style-37 is 2 door sports coupe; 67 is 2 door convertible. These are the only two style codes for a Super Sport.6) Model year-will always be 0 for 1970. 7)Assembly plant-70 Chevelles were built in Atlanta(A), Baltimore(B), Flint(F), Kansas City)K), Los Angeles(L) and Arlington(A) in the US. You are fortunate if a 1 appears in position 7, because this in an Oshawa Canada built car and you can obtain a history on the car by contacting GM of Canada. 8-13) The last six are the sequential number, or the order in which the car was built. These numbers can be valuable in cross checking with the pad on the engine for a match, signifying original motor. “
I disassembled the engine after removal for inspection and verification, which in my opinion, is the most important component for proving an LS6. The casting# is 3963512 with a date of C270. This engine was used in Chevelles, Corvettes, Monte Carlos and select passenger cars. For the Chevelle SS454 LS6 it had 450 horsepower from the factory and was a 4 bolt main, which I verified. The C270 is the date of March 27, 1970 which precedes the build date of the car which was the 1st week of April. This tells me that the engine is the correct date and casting number to make this Chevelle an LS6. Also on the front engine pad, I read these numbers: 70R224955, T0325CRV. The 70R224955 is the partial VIN# that matches the VIN# on the plate. The T0325CRV translates as follows: T: Tonowanda Engine Plant 03: this is the month in which the engine was assembled which is March 25: This is the day of the month in which it was assembled C: This letter C designates a Chevrolet passenger car RV: These last two letter are the engine code designation, which are combined with the CRV to decode as follows: 454, 450hp 4-speed, Spec. High Performance After these code and number identifications, I see no other option other than this being an LS6 engine that does match the identification numbers and dates to link it to this particular Chevelle. This Chevelle also has the original Muncie M22 4-speed and the 4.10 geared 12 bolt posi rear differential in the car that also matches numbers and dates as the engine did. The M22 close ratio transmission has a main case casting# 3925661 and an identification code POC23 C. P: This translates as Muncie Plant, 4-speed(passenger, Heavy Duty, Aluminum Case 0: This is the year code, 1970 C: This is the month code, March 23: This is the day code, 23rd of March, 1970
The rearend numbers are as follows: 3969278NF L129 CRW
Now that I believe I have proven that this Chevelle is in fact an LS6, I want to run down the upgrades I performed on the car. Any changes that were made, the original parts were put in the boxes from the new components and kept for the car. This car was a non-AC car so for comfort and not to modify the dash or firewall, I installed a complete Sure Fit Vintage Air AC unit. I also remove the working factory stereo and installed an upgraded AM/FM self-powered stereo w/a CD changer mounted in the trunk. I also sound proofed and carpeted the trunk while working in that area. As far as the interior goes, it is in as nice a shape as one could ask for. The carpet was replaced just due to fading and the front bench & rear seats are in perfect condition. This car did not come with a console due to the bench and the original shifter plate/boot is beautiful. The dash is unmolested, beautiful and still has the original dash pad. The paint and body appears to be rust & dent free. It has original disc brakes in front and drums in back with HD aluminum balanced drums. The suspension is all original and all bushing have either been replaced or are in great condition. I installed new stainless steel brake lines where needed and a new stainless steel fuel tank w/sender and straps. I ran a high pressure poly fuel line from tank to fuel pump w/AN fitting at the pump, along with a new inline fuel filter. I left the original fuel venting system in place and bypassed it due to age of components. In my time I have never seen this system so complete in any car I’ve restored or worked on.
While the engine was out and disassembled for verification, I installed a hydraulic roller valve train w/gear drive; aluminum timing cover, new gaskets, Edelbrock dual quad Endurashine intake/carb package; and a GMPP Serpentine Conversion kit. I reused the HD 12”clutch and blow proof bellhousing. The driveshaft has been high-speed balanced. In the end, it was a 400 labor hour build on my end. I gave it the same attention to detail as I do on a full custom build; I also used the same quality level of parts as I do on the custom builds.
In closing, if I had to grade this car overall, I would give it an 8 of 10 for an unrestored vehicle. It has all the potential to be a great overall/everyday driver with very few changes/upgrades while at the same time, it would save very rare parts from potential damage in the process, or it could be preserved and put into 100% stock form for a collection piece. Either way, this car is one I would personally love to have and enjoy.
