you can-but it won't run like that.

what you can to is have 4.125 sleeves installed-they usually go for $1600.00 installed

How big can you safely go on stroke in one of these sleeved 4.125 bore LS3s in a boosted engine.

Sleeving

I don't know who you spoke with at Darton. $3,500 is not correct. Even the MID sleeves and install are a lot less than that.

I'll send you a pm on pricing and the best way for you to achieve your goal.

I run a VA Speed Darton sleeved LS2 427. Setup properly, these can last a long time and are VERY strong.

boosted engines should not go over 4'' stroke on a stock deck height
