SupraGlue Posted February 12, 2003 Report Share Posted February 12, 2003 I've been learning a little more about GM's Vortec 4200 inline six after taking a look at one on a stand at the Detroit Auto Show. These articles have some good info on it: http://www.edmunds.com/ownership/techcenter/articles/44833/article.html http://www.popularmechanics.com/automotive/auto_technology/2000/11/new_engines_for_2001/ DOHC, four valve, CNP, VVT (exhuast cam only) -- it's undersquare (93mm bore and 102mm stroke), which is good for torque, but bad for revs (6300rpm redline). Still it makes 270hp along with 275ftlb of torque. From the description, the main bearings are girdled. It also has a cast oil pan, and uses lost foam casting (more precise than sand casting) for all the engine castings. All in all it looks like it could be an exciting engine for the boosting crowd. smile.gif Quote Link to comment Share on other sites More sharing options...
controler Posted February 12, 2003 Report Share Posted February 12, 2003 Yes, I have liked the motor ever since I first heard about it. GM made a new platform with trailblazer, and if I had to buy an SUV, that would be my choice. Now GM needs to put that motor(slightly modified of course) in a smaller, more sporty chassis!

Mallard Posted February 12, 2003 Report Share Posted February 12, 2003 GM made a Twin Turbo Blazer and it was in Motor Trend a while ago. Puts out 400 hp at aruond 8psi. Quote Link to comment Share on other sites More sharing options...

copperhead Posted February 12, 2003 Report Share Posted February 12, 2003 too bad those trailblazers need all the power they can get to haul their fatasses around.... the term WEIGHT REDUCTION comes to mind any time i think about a trailblazer Quote Link to comment Share on other sites More sharing options...
