On a 6.0 liter is 4.000 stroker crank the largest I can go without modification to the block? Also since I'm asking does it make a difference which crank go with? There is Lunati, Eagle and few other brands. Big difference seems to be the Pistons that comes with them. Is one brand better than another?

 

As far as stroke length, I think 4.100 is the longest safely you can go. I was told before you'd have to order custom pistons as well, as there arent any off the shelf 4.1" stoke pistons. unsure on what rods it would use. As for quality, I hear that the lunati crank is better, but I have yet to hear of anyone breaking an eagle crank.

Jut to clarify......you can go to 4.100 without any modification to the block.....
