well, i have taken the 446 apart that i did the STR-14 tests on, so heres a little info on what was inside.

OE crank with 6 cracks in it, LY rods resized with ARP bolts, TRW L2295's with the domes cut off, and then deeper valve notches put in, and the block milled a bunch so these are at "0" deck.
the pistons had been hitting the heads, and after measuring the piston to wall clearance i could see why...... .012 clearance.
pistons are to size, bores are quite big, but arent really worn much at all.
this motor was pretty much built this way.
the caps are walking around pretty bad too with the stock main bolts.
the off-the-shelf Crane pushrods are way too long, which isnt surprising seeing as how the block has been decked around .050, and the heads have been milled some too.
i havent cc'd those yet, but i did pull them all apart to check them over.
all in all, they are fine. valve job looks good, springs were still fine.

i put one on the bench to see how it was. its got some really nice low lift numbers on the intake side, but i think he's leaving a little on the table up top to get them.

anyway, here is what it flowed on my bench, on a 4.375 bore:

lift----I/E
.100--69.4/58.3
.200-152.6/110.4
.300-226.5/159.3
.400-262.5/194.8
.500-280.1/218.4
.600-292.2/228.8
.700-301.1/238.3

so.....the rotating assembly is getting upgraded to a 440 Source 3.75 crank and rods, and i have some Diamond pistons coming at .040 over that are a lightweight replacement for the L2295. this way they will be the correct C/H for this block without needing to resort to a custom piece.
i will leave the domes on them since we're looking for a boost in compression.
the block will be getting a tall fill(race car only), and a set of ARP main studs will be used to help with the cap walk.
the heads will be opened up to MW size, and an OE MW intake will be used instead of the STR-14, and finally the cam will be changed from the Herbert 246/253 to something with around 25-30deg more duration @ .050 in the .650 lift range.
then, the car will more than likely get bigger headers and an 8" converter with around 5500 stall.
