Does anyone know which would be cheaper

- New crank, rods, and pistons

- Bore the block, new rods, pistons, stock crank

anyone give me a guess?
thanks

 

A longer stroke would be much cheaper as if you went all-bore you would need to install darton sleaves in your block, which is $$ by itself. (~2400 if I remember right).

 

Stroking is way cheaper. CFI is right, any bore work means sleeves on the aluminum blocks and possible long-term reliability issues. Many are going with the iron 6.0L truck block and 4" stroker kit for the better of both worlds.
Good hone on stock cylinders to 3.905" and an Eagle stroker kit would run around $2500. Check with Keith Craft "www.keithcraftmotorsports.com" for some really good prices on rotating assemblies, long and short blocks, and great advice. Also, many of the vendors to the right ------> can help out big time.

 

Stroke is cheeper.
A 408 is a good option (4"stroke 4030 bore)
Also wait a few more months if you arent in a huge hurry. The 6.0 ls2 block is on its way and the cast iron is bye bye.
