Thanks. What is the bore on the LS7 block? is it 4.125? I cant use that.
I have a rotating assy, 421, 4.030 bore and a 4.125 stroke. Was planning on a killer turbo setup but due to not wanting to buy a high dollar block if i cant sell it i'll put it together and just make a cruiser w/ 900-1000hp.
Is there a stock block w/ a 4" bore with longer cylinder walls?

The bad news is that pistons designed for a 4.125" stroke in a std deck height block are not recommended to be used with a lot of boost or nitrous because the distance between the pin and the top of the piston gets thin. The rings get hotter since they get moved closer to the combustion and the piston gets inherently weaker.
If you're looking for a 900-1000whp, that rotating assembly is a very poor choice.

It would be really cool if someone had all the blocks drawn with all the dimensions on them. A blueprint.
