Thanks,Bruce I would never go past 4.505 on the thin sleeve,you will be less than .070.You can have the block bored to accept thicker sleeves.Depending on your application,try and achieve a "happy medium" and not take too much out of the block as cracking can occurr.

Do you know the thickness of your sleeves and have you done a leakdown test or checked the roundness of your bores?We have a few 588" and 605" but maintain the 4.500 to 4.505 bores even with the thicker sleeves.

For the future over bore's. I would say power diff would go to the stronger, bore with minimal flex also.

I'll take the unshrouded valves of the bigger bore everytime. if i'm worried about stability i'll build a iron or cgi block. BB, TT5,Procharged 3300lb Street Car 4.79/154

Good points I still dont think .030-.060 is going to make a noticeable power diff. They obviously know something if the block engineers say dont go more than 4.505 bore Care to comment on the lash growth on the Maxx block? Seems excessive compared to other aluminum blocks. As much as the lash grows on those, yea I worry about ring seal. I would set the lash at .005 cold and it would be .020-.022 hot. No question ring seal would also vary.... People dont choose a Aluminum block for ring seal thats all Im trying to say. Then complicate the issue with bore the sleeves to exceed maximum bore spec. Now a CG block, that would be a ultimate. I tried to obtain one, seems they liked the idea of it better than the actual product.
