You can get an LS-X block for half that
or just get an LQ4/9 block and have it rebuilt as a 427 too.

There are some features on the LS7 itself that make it
more expensive I think.

i wouldnt go 427 on a 6.0 iron block but a lsx block go for it

There is expensive stuff in the LS7 like titanium rods.

my uncle juni aka red and ready got his ls7 block and stroked out to 441 from RG Motorsports in brownsville tx.

We had a guy on here with a 441 and if I remember correctly he wasn't very happy with it. I believe he blew it up too.
