I did it in my driveway, outside. The tear-down for me took about 5 hours, taking my time. To get everything on took 13 hours, again taking my time, making sure all the mating surfaces were completely clean, making sure everything was exact and perfect. The hardest part was removing the L36 balancer and installing the L67 harmonic balancer, that took a full day by itself until i said the hell with it and did the starter trick. The cost was alot more than i expected, whatever u plan on spending double it, better yet triple it. If u plan on taking on this project read on it until your eyes water, there's alot of room for error, on just simple things, imo every top swaper should get a cam or roller rockers. You will need all the supporting/breathing mods to take on the project too. You can start now by getting a scanner like aeroforce
