Jim builds the engines entirely by himself in his own personal shop. He is the type of person that pays extreme attention to the smallest detail, his builds are works of art. I have great confidence in the quality of his workmanship, quality of the parts he chooses to use, and trust his advice.
I just bought a short block for my track car a couple months back, it has tremendous ring seal, yet turns with less drag/friction than any engine I've worked on. The guy knows his stuff, yet still has a common sense approach, he won't spend your money carelessly. Maybe his prices have changed, but my invoice shows 2.5K for the MACHINED Dart SHP block. Quite reasonable if you ask me.
My apologies to the OP for the off topic post.
