suped up 6

Thanks for all the input. I would eventually like to rebuild the engine, but since it runs for now, I think that will be the last thing I do; it needs new suspension, and desperately needs to be rid of rust. I want to rebuild it for a couple of reasons; I want the experience and satisfaction of doing it myself, (I've helped out in the past with rebuilds), and I would like to increase the performance. But, like I said, that won't be for a while.
Thanks!
Thomas
