Very nice . With good headers looks like your in ilmor v10 and the blue whipple motor territory .should be a runner

Well, everything went to the machine shop today. We're on our way!

Initial thoughts are that 1) the block is in great shape and we're pretty confident that a hone is all that's needed, 2) pistons are good with the exception of the one. The other two can be cleaned up, 3) the condition of the parts overall was very good showing minimal wear, and that this will be considered a refresh vs any real rebuild. All great news!

I should have everything back in a week or so. Then it's off to assembling everything.

The cool thing is that the machinist was commenting on how great all the parts were. He must have said it like 10 times!

FYI,,race tek is the old owner of je piston so he is not new in this game..he had a claus that he could not make pistons when he sold out so now he is back into the game making a better quality piston with out the long wait times...yet! when you have the block honed make sure the machine shop use's deck plates to true up the bores..
