73 400 block std bore. front 4 have Program billet caps, center 3 splayed. Milodon studs. This block had the caps installed and machined by Dan Whittmore, its done right. It is also filled to the bottom of the pump holes and was cured for months with a tq plate installed on each side. It has a BOP rear main seal in it.
1400$
Std bore 400 blocks are getting hard to find, this one is as good as you can get.
I have a new SD Megga Brace the 100% version, 300 new, 150 $ if someone buys the block.
The rotating assembly is a new Eagle cast 4.25 crank. It is balanced, cut .010-.010 and has FM race bearings. Rods are new PPR 6.8 4340 steel billets, ARP 2000 bolts. 1000HP rating.
Pistons are new Butler Ross 4.155 Fts, come with tapered tool steel pins, locks and file fit rings
This rotating assembly is balanced by Dan Whittmore. Crank thrust was polished so no issues there. 1250 $
I can separate if the whole thing does not sell. You can make a 600+HP stroker with this easy. I was going to upgrade the crank to 4340 steel and go for 750 HP but bought a IA2. Blocks like this are getting hard to find and these rods are available only in 6.7 now.
Also have the Crower solid roller and lifters I was going to use with this as 600 HP, new.

I will come down to 1250 $ on the block. Give the buyer some room to bore and deck it. I will take some pics of it next time I am at the shop.

The rod on top is a Crower 6.8 4340 billet. You can see how close a copy the 2 rods below are. The pins,I paid extra for the good tapered tool steel ones.
Rings are Seal Power File fits. Bearings are FM Race Bearings. Mains have the oil "slot" vs the round hole.
Block has a BOP rear main seal installed. This is a fully balanced rotating assembly. Have the crank card with notes.
Will get some pics of the splayed cap, std bore block up.

I assembled the engine after I could not find any buyers.
