440 engine build I wanna take a stock ls1 block and build it as a 440 stroker while using 241 casting heads ported with larger valves. Trying to make 500 RWHP undercover in the apperance of a stock ls1. I'd like to keep the CR around 10.5 to 1 Any thoughts.

No, i know i could save money going that way but i want the appreance of the ls1 for several reasons weight being the biggest issue. Sleeveing the block is no problem. Has anyone completed a similar build, from what i have read 440 is about all i could get id realy like to go bigger.

The problem here is the bore, if you go to a 460 the bore is so big the sleeves are worthless outside of a NA motor and there is no room to re machine if nessary. I need more stroke.
At 440 the sleeves still have enough meat for a turbo or nitrous with a little room to re machine if somthing happens. I'm just not sure what heads i'll need for the motor to work right. I could use aftermarket heads if i had to.
