---Engine Identification Thread--- You guys need an Engine Identification Thread 
I know, I am in the wrong forum but-but-but?!! Please answer ID question;
All black 454 "New Mr Good Wrench 454" says this right on the valve covers and of course mechanical fuel pump.
Block Casting Number 12550313 (DeNotes: 454, 4 bolt, Generation V crate motor, Generation VI 4.25 bare block, fuel pump boss)
Bought in about 2006, installed in a 1984 33 foot Southwind Motor Home and is on it's way out
Pulls the Motor Home around like it might give a 1978 smogger Corvette a run for it's money
No Deck stamp
Year? HP? Heads?
Lopes, Rocks and Thumps like an LS6 but, what the heck is it, ID and or internals please?
Also, 454 casting #14015445 (Denotes: 1986 - 1990 Motor Home 454 4 bolt mains and Peanut port Heads)
Deck stamped "CH3336968"
Year? HP? Yes, peanut port Heads
What is "CH3336968" deck stamp?

Post this in the big block forum and you might get some answers. This is an LS engine forum.
You have a Gen V Big Block, not Gen V LS
