Where did you find pistons and rods for $800?
That rod/piston combo is the same I went with- $800, ARP head studs- $110, Fel-Pro gasket set $100, Bearings $150, Cylinder head machining and freshening was FREE for me, but that's because I had the machine shop I've had do all my sublet work for through my shops do it, so they did it at no charge. I got a "low-mileage" block in good condition for $150 with 60k on it. Really, just cleaned it up and honed it. Even with having to buy a crank and 2 K1 rods on by rebuild due to oil starvation, I had about $1800 in it. I have a good relationship with the local parts stores in my area, so when I rebuilt it, they just warranted the gaskets and bearings for me.
