Default 401 All Bore

Anyone thinking of building one? Resleeved ls1 MID block 4.200 bore with some new ls7 heads and intake utilizing the stock crank? This is what I am seriously contemplating building soon. Should be good for near 570 rwhp NA.
Just looking for the most power per dollar. What kind of numbers do people get with a 4.125 bore stock stroke stage three headed motor? Steve @ race engine developement is getting the new larger darton sleeves next month for the 4.200 bore. I think that would make an excellent bottom end for the new 1s7 heads and intake.
