well I'm not trying to get started here so I did not hit the disagree button like I really wanted to but my friend that is running a stroke big block (74 Duster) in the high 9's is not using any nitrous (I think "nos" is what the tuner guys use) and if your Sly comment is referring to my stroker being underachieving that may be in your eyes but it has achieved everything I've ever wanted it to. The idea of using aluminum heads is just something I've always wanted along with trying nitrous is something I always wanted to try. Unfortunately the reoccurring cost of nitrous will keep me away from it.. unlike the aluminum heads are just a one-time cost hopefully lol...
