although i have a nitrous motor, i went with an iron block for the same reasons. cubes, strenght, cost, and the fact that i had on laying around. on the strenght issue, i have seen plenty of LS1s in machine shops because of cracked sleeves. i have also seen several that would break pistons and due to the extra pressure, crack the sleeve at the same time. if those were iron motors, they could but be bored if the walls got hurt. although i would rather have a darton sleeved aluminum motor if i had the money. oh yea, and i was able to squeeze 380 cubes out of mine with the stock crank offset ground down to a 2.00 SBC rod journal

i gues on the calc you could put .0001 and subtract .006 from the gasket thickness.

your talking about the new ls1 engine girdle, yeah you do not need to run an Iron block any more, I am the engineer who devoloped it, I am the only person you can get it from , as I am going to recieve the patent for it, I am selling them on ebay check it out (under seach type in ls1 engine girdle), it boxes in all the mains, decreases windage, less friction in the piston area, and increases tortional rigidity, just an awesome piece.
