how much do you think it would cost..

[farmtruc]

to bore out my 5.3L block to a 5.7L then have it honed, line honed, decked, and have the block cleaned up...

I just built a 383 from a 5.3L block, it was machined and a full rotating forged assembly from Eagle, under $3K.

As for what you want, a set of pistons about $800, then about $500 for assembly and boring.
