Oh man!! Been there, Done that!!! I feel for you. I have sold myself on the same thing... no more engine rebuilds or tranny pulls at home... not to mention one engine I did over a period of about a year on and off... when i finally got it done It went kaput after 5 mins. I had forgot to tighten the connecting rod bolts...

had to swap everything to the engine I pulled out to replace with this one.... at least I had 2 blocks
