Update from Al.
"
Been driving the Chevy for almost two months now and I am very happy with it. The car is very responsive in all gears and is very smooth right from a cold start up. It seems to just sip the gas even though I am driving it pretty hard. The split manifold and dyna flows are ideal as they really rap when you put your foot in it, but are very quiet with no drone when cruising or driving at a steady speed.
I have some minor issues to work out but overall I would recommend this swap to anyone. If I kept the hood closed, no one would know that the sound is coming from a modern OHV (edit DOHC), fuel injected, four valve, cam phased, Atlas motor from a Trail Blazer. However, when I park it at a show, the first thing I do is open the hood."
