that's a good point... but to put a finer point on it, the LS1 is NOT a "Chevy" engine. It's a GM corporate powerplant. The SBC became the corporate V8 after GM phased out divisional engines. Now... IIRC, the Firebird ran a 301 Pontiac motor for a few years into the early 80s. Then swapped over to the 305 and 350. Cadillac did run their own V8 for a long time, the 4.0 and 4.5 litre pushrod motors were pretty much Caddy through and through. All aluminum, too. The Northstar was the son of LT5 and was Caddy only until Buick used it for a while. The V6s were either Chevy (2.8-3.1-3.4-3.9) or Buick(3.8). I don't rightly remember the source of the 4.3... for some reason, I think it's a 350 with 2 cylinders lopped off... but I am not sure. The 4 cylinders are all new and part of the GM Powertrain family of engines. The old pushrod I4 was actually available in 1980s in the base Camaro and Firebird. After Ford did the Mustang SVO, I always thought it would be neat to take the Camaro, put the Z28 suspension under it, 5spd manual, and a turbocharged Quad-Four I-4. Think about that combo. A real BMW killer. The engine could have put out big power (reliability be damned, right?) and it would have been big time lighter. Pontiac did do something like that with the GTA... the Buick turbo V6 in the Firebird. It did take different heads to make it fit in the smaller car, but what a rocket that was. One of the fastest cars of the 1980s. Also, Pontiac didn't like a "Buick" engine in their car... tough shit. They replaced a Chevy engine with a Buick engine... The last year of the 3rd gen Firebird, SLP did the Firehawk... not many made... hot L98, ZF6spd... one bad assed car and worth a chunk today. |
