Did you miss it last month? CC built a very basic Buick and dyno-tested multiple combinations of two camshafts and four intake manifolds. It was entertaining, but the dead spot was in the stock cylinder heads. This month, the resolution: We're going to see how the stock, Stage 1-spec iron heads look when faced with Edelbrock and TA Performance heads in this big comparo of price, features, and power.

With the 70cc chambers in the baseline iron heads, which TA upgraded to Stage 1 valve sizes, the compression ratio is a measly 8. Thanks to local Buick guy Bruce Kent for loaning us a flywheel. The variables in last month's testing were the cams and intakes. That's the cam and intake used for the first set of head testing, but stay tuned near the end for some info on a combo with a smaller cam and dual-plane intake.

Stock Vs. These heads feature 2.

The Edelbrock chamber size is 68 cc, so the compression ratio was bumped from 8. If you're doing a swap on an otherwise stock engine, you'll also need to order longer pushrods, though the specific length will depend on the aftermarket rockers you choose. The stock Buick ratio is 1. Stockers usually don't. But even if they do, the difference in lift between the 1.

If a little bit of lift is worth a horsepower or two, then it's made up for in the roller rockers versus bearingless shaft rockers. We ran the Edelbrock heads with the as-installed valvesprings. There's a bit of apples and oranges going on with minor differences in compression and valvetrain, but we feel comfortable bench-racing it into irrelevance, especially when you see the huge power gain when going from the stockers to the Edelbrock heads.

The Edelbrocks killed the stockers at every point in the rpm range; at the peaks, they were better by 24 lb-ft and 42 hp. Combined with the weight savings of the aluminum Edelbrocks, that's really significant. And if you like the bragging number, the swap took this mild Buick from hp to hp at 5, to 5, rpm. Peak torque was lb-ft at 3, to 4, Costwise, let's assume you're building an engine from scratch.

Chances are good you'll need custom pushrods for either combo, so that price is a wash though technically, the Edelbrocks require hardened pushrods for guideplates and the stockers do not. Edelbrock Vs. The big claim to fame on these is that they look totally stock with all the factory contours, unlike the Edelbrocks with their flat-machined ends.

Paint the TA heads and they could pass for OE equipment. They also use the factory-style shaft-rocker setup rather than the Chevy rockers. TA claims that no additional parts are required when swapping these heads onto a running engine, though we found that not to be entirely true: The rocker pedestals are 0. The TA heads also run a little harder than the Edelbrocks, delivering slight power gains above 3, rpm that grow to more significant improvement above 4, rpm.

Peak to peak, the TA heads gain 7 lb-ft and 12 hp. The biggest separation is past the point of peak horsepower; at 6, rpm, the TA heads are better by 25 hp.The first version replaced the Buick straight-eight. All are naturally aspirated OHV pushrod enginesexcept for an optional turbocharged version of the short-lived used in the Oldsmobile Cutlass. Some of these Buick V8s, such as the, andhad the same displacements as those from other GM divisions, but were otherwise entirely different engines.

Buick's first generation of V8 was offered from through It became known as the "nailhead" for the unusual vertical alignment of its small-sized valves, features that were the result of putting both valves on the intake manifold side of the "pent-roof" combustion chamber used in this engine series.

The small-diameter intake runners allowed these engines to develop high torquewith many exceeding one foot-pound per cubic inch, exceptional for the time. All of the nailhead designs have a 4. The smallest displacement Nailhead, it is a small-bore version of thesharing stroke and deck height but having its own 3.

The was also used in the through 10,Series conventional cab Chevrolet heavy duty trucks. The was introduced in and produced through Buick, like most of its competitors, continued to expand their durable V8 engine to larger displacements, such as the 4. Originally ait was later redesignated a to meet s GM directives for maximum displacement engines in mid-size cars. The engine was variously designated the WildcatWildcatand Wildcat depending on the foot-pounds of torque each version produced.

The Wildcat was the two-barrel carbureted engine, standard on the LeSabre.

The Wildcat was a no-cost option for the LeSabre that used a lower compression ratio to run on lower- octane fuel. The various Wildcat engines had decals on their air cleaners indicating their version; however, the four-barrel edition of the small-block Buick V8 was also labeled Wildcat on its air cleaner, but was not a nailhead engine. The Wildcatwith a single four-barrel carburetor, was the standard engine in the InvictaElectra— Buick WildcatRiviera and Riviera the and Riviera models used the with a single four-barrel carburetor, labeled Wildcatas standard equipment.

Mounted on a trolley, Buick s were also used as starter motors for the SR Blackbird supersonic jet. In an effort to overcome the restrictive exhaust-port design of the nailhead, Buick drag racing enthusiasts in the s adapted superchargers with a custom camshaft to feed intake air in through the exhaust ports; the larger intake ports became the exhaust outlets. The largest-displacement version of the nailhead, it began as an option on the Riviera and was later available on the Wildcat and Electra models.

The and Riviera used the engine as standard equipment. Four-barrel carburetion was standard on the basiccalled the Wildcat for the foot-pounds of torque it developed.

For the buyer looking for even more power there was the Stage 1 option. Though Buick claimed the Stage 1 system was only good for 10 hp, quarter mile times for Stage 1 Buicks were nearly a half second better than the standard GS cid. A Stage 1 engine featured special ported heads with larger valves and revised valve springs, a hotter camshaft, and a tweaked carburetor.

These improvements along with a 3. With sticky tires a Stage 1 Buick was capable of low 13 second quarter mile times.

Each featured different bore and stroke dimensions and horsepower ratings. The two s were clearly Buick and Oldsmobile's answer to the muscle car rate of the s and early s, but neither automaker received credit for producing performance street cars.

The glory period was short-lived. Tighter emission control standards and high insurance premiums in forced Buick to detune the engine to horsepower in the Riviera and on the Gran Sport models.
