5.3 engine - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just acquired a 04 Trail blazer with the 5.3 engine. Has 151,000 miles, runs decent, 4 wheel drive. Has a blown right hand exhaust gasket. Thinking of maybe putting drivetrain in my 69 stepwise. Does anyone know what horsepower this thing has? I like the idea of the fuel injection and maybe gas mileage of the overdrive. It may have a 700-R4, but not sure. It's almost to nice of a car to part out, it's loaded up, but I have no use for it. What do you think, what do I need besides drivetrain and computer?
