First decide if you want a full size or compact. They've both been done more times than I can count. Consolation is that I think Hooker makes headers for the S10 but not the fullsize. If you want to bring more than one buddy with you on any road trips you'll need a fullsize. Towing with an S10 will be limited due to the light weight of the brakes on it. The swap is relatively easy into a fullsize if you have any mechanical abilities. Check past posts. We've posted on this topic so many times that doing a little research will show how easy it is. Also, the pinned topic in LS1 Conversions lists all the items you'll need to do the conversion.
