Yep, manifolds are a must for me. 512 inch low deck with RB mains, cross bolted main caps, roller bearing camshaft. CNC ported Mopar 452 heads. Callies crank, Crower rods, custom Diamond pistons. Tons of custom stuff, the dang project took me about 5 years. I think the guys at CRE machined this block back in 2005.
