I did consider assembling this myself but relented as their assembly came with a warrantee ....otherwise I would really be shafted (not to mention I have not assembled an engine in many years and don't have all the tools anymore)
Everything I have done on this truck I did myself and am very happy with the truck. The one thing I job out and I get jobbed on it.
I am afraid I will never be comfortable with this engine I will always be waiting for the next problem.
