Re: Cylinder wall thickness
There were some thick blocks in 67-69 era. Back when I was more adventurous, we took some old blocks, filled them, bored/honed to 4.560 and put a 4.625 stroke to make an alcohol 604" It required a main girdle and good caps to hold things since the cylinder walls were at .060" +/- a little.
They didn't stay round very long as one might expect. That was back around 1990 and the only aftermarket blocks were KB. Thought it was worth a try. It wasn't.
