Can this be duplicated with a 5.9 build??

Since a few people have asked, its real simple.
Stock mag block, dissembled, machine shop cleaned.
The usual rebuild parts, new cam bearings, soft plugs etc.
Stock bore just a fresh hone.
Keith Black 107 pistons.
Stock rods reconditioned.
Crank turned .010/.010, balanced with mallory added.
The cam was a comp 262 roller for a LA. The truck it went into was a 78 W150.
The stock heads were cracked, so I bought a new set of eldebrock magnums, and had the machine shop go thru them.
I lucked out and bought one of the last M1 duel plane aluminum intakes for a carb.
Ran a 325 street demon carb.

Nothing fancy, I just picked my combination of parts and built it.
