Ooooo, ya sure that was a 427 block...

...cuz that's way too thin. Either that or you'er a victim of a massive case of core shift. I have to say scrap a 427, but it sure looks that way. As they say, pay me now (new block or sleeves) or pay me later (broken block/low power/overheating).

I've been told that 427's were good for 0.080+ over and it looks like your's was marginal at standard bore -- 0.065 (current wall thickness) +0.060 (overbore) = 0.125 wall (original standard bore) which is the low end of acceptable.

Please refer to my earlier post on this subject...http://jcoconsulting.com/forumfe/reply.aspx?ID=9993&Reply=9993 -- this subject has cost me a lot of money over the years so learn from my experience, not someone else's hearsay!

Regards,
Dan
