Ummmm. I guess We better be more observant.
Go to the pic and count the holes, something doesn't add up to 5.9L
"Supplied by Woodruff Diesel, the billet block began as an 1,800-pound rectangle of steel and, after a lot of machining, the finished weight was 540 pounds. The block itself is dry-sleeved with a one-piece bedplate and four-bolt main bearing caps. The bedplate ties the block into the mains, pan rails, and engine mounts. Woodruff Diesel also supplied a counter-weighted OEM steel crank that spins six 4340 billet connecting rods, and six forged pistons from Ross with Total Seal rings. The camshaft is a custom billet roller with roller lifters, heavy-duty pushrods, and roller tip rocker arms. A 24-valve cylinder head with double valvesprings and a serious porting job accompany the custom stainless steel intake plenum and exhaust manifold."
How do they stuff those 6 pistons in 4 holes?
