i would like to know how big you could make a iron block , i heard you could go 400ci with the stock crank? what would i have to do to make it that big ,,,,, and do i have to chang my crank or have some work done to it? i know you could make it in to a 375 with 60 over but i would like to do more if i was going to spend the money,,,

ps does any one know how much it costs to have the ls1 block resleeved? and bored over thanks

 

I have a 6.0 block bored to 4.060 and a 4.000 stroke Lunati crank offset ground to 4.075 for a 422ci and almost square motor.

 

I have an LS1 iron block .060 over and matching forged pistons for sale cheap in southern california. See my post in the for sale section.

A 4.19 Bore with a 3.62 stroke will give you a 400.

You might as well resleeve an aluminum block to get that bore.

375 is about it with a stock crank, but that is 30ci more than stock, a pretty good increase.
