it’s an LS series motor. not an LS1
I think it is easier to say an iron block LS1 then saying a brand new rebuilt 5.3L block bored out to 3.930 with ls1 internals, cam, heads and intake. 
SRSLY?
Anyone?
I’ll even consider aluminum shortblocks.
You should fire sale the red one while this one is still for sale.

But you would still need a new shortblock. 
Maybe if v8rx7 forum worked lol.
That site has been shitty tits lately.
GIMMIE TEQUILLA.
And an ls1.
Seriously? anyone have any tips on where to get one locally?
V8rx7forum is on a pretty steep downward slide, most of the useful people have either been banned or left, they went to norotors.com.
If you want a 5.3 in pieces I could help…
Cash in hand…
Up.
Considering all aluminum third gen blocks.
