We are looking at a 1973 Chevrolet Camaro powered by a built GM LQ4 V8. If you are not familiar with the LQ4, it is a 6.0L mill which came from the factory in some of GM"s harder working vehicles in the late 90s and early 2000s. Think full size vans (Express, Savana), the 2500/3500 pickups, and the large SUVs (Suburban, Yukon). Power output varied by application, but the numbers ranged from 300-325 hp and 360-370 lb-ft of torque.Now, if you put a stock LQ4 in a 1973 Camaro, it would probably make for a decent running car. The more powerful variants made 325 hp at the crankshaft, would translate to somewhere in the area of 270 whp. The most powerful engine offered for the 1973 Camaro offered just 245 horsepower, so the stock LQ4 would make for a much quicker car.Fortunately, the LQ4 in this 1973 Camaro is not stock. It has been fitted with a set of LS3 cylinder heads and an LS3 intake manifold. The reworked top end is paired with a big camshaft and a full exhaust system. The no-name exhaust seems to be straight off of eBay. There are a few other supporting items, as well, but those are the main bolt-ons. For the record, the power from that worked truck engine is sent through a built 4-speed manual transmission.The results? 421.5 horsepower and 416.8lb-ft of torque at the rear wheels meaning that this 1973 Camaro makes more than double the stock output of the most powerful factory-built Camaro from that model year and the builder has achieved those numbers with a mildly built van engine.Tags: 2g Camaro, 2nd Gen Camaro, camaro, chevrolet Camaro, Dyno Blast, Dyno wednesday, Lq4
