Its not exactly feasable for me right now, maybe if i save my money for like a year i could do it lol. But i'd want to share my crazy idea.

Ok 6.0L iron block. Ok? great.
-Bored to 4.125"
-Stroked to 4.000"
427.649 CID

How feasable is it with the 6.0L block having a 4.4inch center to center cylinder spacing to get it bored to 4.125"?

Another option would be,
-Stroke to 4.100"
-Bore to 4.075"
427.778 CID

Heh i guess im kinda obsessed with 427's

 

You can't bore a 6.0 more than .060 over, and that's a tad bit pushing it.

Oh well guess i cant win em all.

I guess the only way to get to a "427" would be probably too much work. Unless its not too much work to increase the stroke to 4.2 inches that is assuming a 4.030" bore. (which yeilds 428.587 cid)

Oh well maybe i should just be content with a 408 project

 

You could go with the c5r block

or the ls7 crate engine
