I have to say I have been impressed with this forum overall and all of the sub forums I have visited. Helpful people and very few snarky replies. I wish all forums I use were this good. I have been here observing(lurking) for a couple of years. Once I joined, I have learned a lot. I don't think I even knew of this particular sub forum until I started looking more seriously at swapping in a LS type engine. I have been working my way back through the pages and it has helped make me aware of many pitfalls to avoid.
