Need 400 SB and BB info

[volspeed1970]

A little info regarding this topic from an automotive author friend of mine: The LS3 402/330hp engine could be ordered in any non-SS equipped Chevelle model. This included coupes, convertibles, 4-door hardtops or sedans, El Caminos, and even the station wagons. Chevrolet referred to this engine as the <span style="font-style: italic"><span style="font-weight: bold">“330hp - 400 Turbo-Jet V8”</span></span> in a magazine ad in 1970. That is why most Chevelle enthusiasts refer to these cars as “Malibu 400’s”. When this engine was ordered it did not come with the SS engine chrome accents (valve covers and air cleaner lid), but it did get the 12-bolt rear axle. Also of note was the air cleaner was a single snorkel closed element type. The decals on the air cleaner lid were the <span style="font-style: italic"><span style="font-weight: bold">“cross flags” with 400, and the horsepower read 330</span></span>. Unlike the SS models, power disc brakes were not a required option. These cars had no visual differences indicating what was under the hood other than the “400” engine emblem located above the side marker lights on the fenders. The SS’ domed hood, and the ZL-2 “cowl induction” hood were not available with this engine option. Most people aware of the &quot;new for 70&quot; 400 small block which was only available in the Monte Carlo and fullsize cars, and assumed when they saw a Malibu with the 400 engine emblem on the fenders it was for a small block. That is not the case as the 400 small block was never installed in the Chevelle. Also the small block 400 is referred to as a <span style="font-style: italic"><span style="font-weight: bold">&quot;Turbo-Fire&quot;</span></span> engine like all other small blocks were in 1970.
