The engine is an L79 high performance 327. The L79s were famous for their “double hump” heads with the 2.02” intake valves, a forged crankshaft and a large harmonic balancer. The engine in the car originally came from a 1967 Chevelle. The engine was given some old-school TLC with the block being deburred, the connecting rods shot peened and polished, and the heads deburred and ported. Consistent with mods of the day, a vintage Edelbrock intake manifold, a Comp Cams (270), a Holley Double Pumper (600 CFM), and Hooker Headers were installed. The push rod throttle linkage was converted into a cable linkage setup, and a modern MSD electronic distributor (no points) was installed. For the oil system, a high pressure oil pump was installed. The oil filter was converted from the stock canister style filter to a modern screw on filter. Due to the higher oil pressure, the oil filter is a type that is normally found on Fords (the Chevy filters are small) that has a hard case and a nut on the bottom for installing. It should be noted that the oil pan may need to be replaced sometime in the future. The drain plug was stripped by the previous owner who just tapped it and installed a short bolt. The PCV system is from a stock L79. As a result, the engine does not generate enough vacuum with the installed cam at initial startup. For engine cooling, a four row radiator from Original Parts Group was installed. The previous Power Glide transmission was replaced with a Turbo 350. A beefed up transmission cross-member was installed to support the T350, and stiffen the frame. The gear selector linkage was changed to cable, and a new gate and plastic indicator was installed on the shift lever (2 speed to 3 speed). The rear end is a Moser 12 bolt with 3.73 gears, and a torsion style limited slip. It is built for about 700 HP. The Moser rear end has pressed on Ford style bearings (no C-clips). It also has larger “ears” on the top of the case that connect to the upper control arms. This eliminates wheel hop (good) but also raises the rear roll center (not as good for carving mountain roads, but still okay). The larger ears required adjustable upper control arms. By the way, the rear suspension has a 1” drop spring to keep the stock ride height with the larger rear wheel/tire combo. Urethane bushings were installed to attach the body to the chassis. The front suspension has been completely rebuilt with new ball joints, etc. The lower arms are stock with urethane bushings and the upper arms are performance tubular arms with rubber bushings and offset shafts. Using the performance upper arms allows the wider tires, more caster, and more camber than stock. Alignment was dialed in to get “even wear” across the tires and good performance/feel with braking and cornering. The rear suspension was beefed up quite a lot when the Moser 12 bolt was installed. The upper arms are adjustable with spherical bearings on the chassis side and rubber bushings on the rear-end side. The lower suspension arms are square section arms with spherical bearings on both ends. A heavy anti-roll bar was installed on the front and no anti-roll bar on the rear (again, good for carving mountain roads). The brakes are vacuum assisted with disks in front and drums in back. If you take off one of the back tires, you will notice that spacers were installed between the wheels and the hub to accommodate the extra space needed for a future rear disk brake installation. The exhaust system is from Flow Master with 70 series RV mufflers. The wheels are from Wheel Vintiques. They are the 90 Series Billet Rallyes. Note that the center caps are not the same between the front and rear. The manufacturer changed the wheel/cap dimensions between the time the front wheels were ordered, and before the rear wheels were ordered. The tires are all BF Goodrich, except the rear tires are more of a racing tire. The Chevelle (a California vehicle) was purchased from the previous owner on 11/17/16. I later purchased patch panels for the rusted out lower quarter panels, and panels under the front windshield and rear window (common rust areas for the Chevelle), and took time to do the body repairs correctly in 2017, and restored the vehicle to an all-metal rust-free restored body. Car was sanded down to bare metal with two coats of primer added, and painted in the original gold in July 2018 by a local White City, OR painter. The painter stated that he judges a vehicle by what’s underneath the paint, and indicated that my Chevelle was the best he’s seen. A new front windshield was installed along with all new body and window seals along with new rear window mirrors. Following painting, the TH350 transmission was rebuilt by Hi Tech Transmissions, Central Point, OR, with a shift kit and the original B&M Holeshot 2400 stall-torque converter was replaced with the correct torque converter for improved street performance. The ignition switch lock was replaced in August 2018 along with new carpet, headliner, center console, and clock from OPGI. The sun visors and rear dash were covered and carpet was installed in the trunk. In September 2018, a new stereo system was installed by Progressive Audio, Medford, OR. For the issues noted above, I discovered that if you allow the engine to warm up for the first startup of the day, and establish brake booster vacuum, then the brakes work fine thereafter. For the oil pan plug issue, I purchased an aftermarket oil-pan magnetic plug kit to fix the issue without having to change the oil plan. I have the new magnetic plug and removal tool, and a new oil filter, but haven’t yet installed them. The Chevelle has always been kept in my shop since I’ve owned it and driven very little. It has only been driven for the last couple Medford, OR Cruises. I live on a dirt road, which is not conducive to having a nice classic car. Thus, the reason why I’m selling it, plus I have another project to work on (a 67 Corvair Monza with a 140 HP Corsa engine). |
