The Stovebolt Site Forums The Shop Area General Truck Talk An in the crate engine-is it different than what Chevy puts on 2006 models?

Any way you look at it, a freshly built, properly tuned crate 350 will produce less emissions than a 1946 216 oil slinger. The crate engine is not a 2006 model engine, they don't make a small block any more. It's just a rebuilt core that could be originally from any one of 3-4 past decades.
