Go big on an LS1 or LS2?
I see no reason why a ls2 block couldnt be sleeved with a 4.200.
If you are on a budget, why not just get an ls2 stroker... stick a 4.100 crank in there on 6.125 rods and its around 412 i believe...
30 over on the pistons or so...
contact Steve Demirjian if you would like one done, he's the man, period. also you can ask steve about the 4.200 sleeves or i can find out an estimated ETA for you.
the MTI 455 was a 4.160 bore and custom 4.185 stroke.
