One of Mikes concerns is that everyone might be going to retrofit the new Trailblazer engine into their hot rods. A lot of people are thinking that it is the cats meow! You can make simular HP & torque numbers w/our old inline sixes. Douglas says those 250 & 292 Chevy's are making 800 HP for the street & up to close to 1300-1400 HP on race cars. If you guys look at those Brazlian Chevy inline 250's & 292's. Look at how much power they make w/the stock cast iron head. They run small turbos there. Master Power does not make big turbos like they do here in the US.
