Hi,
What would be a ball park figure for a shop to bore out a ls1/6 engine to 427, 434 or 447. I know I just gave three displacements but I'm trying to figure out cost. The cost of the rotating assemblies don't seem to be that different. Thank in advance.....

I believe that needs to be sleeved to achieve that bore.

to get that big you would definitly have to get the block resleeved. LS1 + new sleeves = $$$$

 

Going rate use to be $2500 for a resleeve. Just go with an LSX block if you are still considering big cubes.

I think its like $1,600 for the new Darton sleeves installed, the long 5.800" ones. You can easily make a 447 out of it.
