nice, but one question. It's not a true big block if it will accept LSX smallblock heads, is it? Or is this one of those small blocks that are bigger than most big blocks?

**Sarge** · 10-31-2006, 01:40 PM

at a 3.990 stock and a 4.250 max bore...and look at the tall deck capabilities....holy shit...you can go 500 cubes properly stroked man and still have .200 clearance between cylinders.....and use LSX heads....Somebody did their homework.....this thing is a beast of a block....and interchangeable.....gotta love it...

Rumor is no more than a LQ9 ....or damn close to it...so affordable....
I tell you GM is after the aftermarket crowd....

As I was reading the specs I was thinking of the LS7X Warhark block that world products makes. It doesn't seem so different. I think Sarge is right... GM is going after the after market indeed.
