Iron block maximum bore How much overbore can the iron block stand up to??
I am thinking it could go 4.100 with no problem
since it is really only .050 off each side of the bore. And the block looks pretty thick to handle it.
Maybe more????

Re: Iron block maximum bore My block is not resleeved. The 5.3L has a lot of extra meat on it. Stock bore size is 3.780 for the 5.3L block. Mine is at 3.910. That comes out to .130 over by my math <img src="gr_grin.gif" border="0">

Re: Iron block maximum bore It is possible to bore a stock cast in liner completely out and put in a conventional stepped pressed-in liner to obtian SAFELY 4.080. Basicly known as sleeving. Or your floating on block material.

Re: Iron block maximum bore Golden West Performance was going to give me a 427 by boring 4.060 and 4.125 stroke. But, Kenny got uncomfortable with the 4.060 bore (he felt durability/reliability would suffer) and recommended I stick with 4.030.
So 422 it is.

Re: Iron block maximum bore Evidently, the 4.8 and 5.3L blocks use different liners than the 6.0L block.
Certain 6.0L blocks can be bored over .06 after the cylinder wall thickness is checked.
I think I've heard of an iron block going out to 4.08 but, I don't remember where I heard this.

Re: Iron block maximum bore My 6.0 block is bored .060 over.
.030 over is no sweat, ditto for .040. But .060 will make you look at the coreshift a lot more.
I have heard of two 4.080 bore 6.0's but have no detail on them might be just rumors.
