If you can't move any more air, you squeeze it harder......be it restricted rules racing or blower engines....doesn't matter.

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!

I had an oso member who's in the process of building a similar 525sc type of build, tell me the 305 AFR's were too big for this build that made 667ft lbs and 691hp . He is going with the Afr 265 ovals on his 525sc build up. It be interesting to see the results of that build. Has anyone done a build like this with those heads ?

Update
My shop called me this morning with good news. Well, mostly good news. My block is good and cleaned up nicely. Only needed a hone. Crank checked out perfect and my rods were all good. Everything is staying standard in terms of bearings. The only bad news was (and I already knew this) that it needs four pistons. I was thinking three, but it looks like four now. He said that he'd only replace one if it was going back together NA, but since it's going to see boost, best to change anything that's even slightly suspect.
Once I get the pistons in-hand, it should be a couple days turnaround time to get everything back. Then I'll start reassembling.
Moving along!
