what to do?

I just built my engine back in the spring. I had replaced the top end of my motor many times before in years past, but this was the first time I did a complete engine build without help. It is feels good knowing that I did it myself, and if it blows I have no one to blame but me.

One thing to keep in mind; the cost of specialty tools for the engine build vs. the cost of having a local engine builder assemble the short block is probably close to the same...or at least it was for me.

I say go for it, just take your time and ask questions as you go and you'll be fine.
