All "X" blocks were cast 318 i believe. Factory says 4.08, but some on various blogs say even bigger. Read that some drag car builds went to 4.12/4.14? I'm not gonna comment more as this is a sale thread.
I know its a sale thread but i felt it was relative info that could help the sale. I know i wouldnt spend $1500 on what i thought was a 318 block lol but since they can be made that large it has alot more value. And now that the info is there unknowing people like myself might be alot more interested
Hows the condition of those main caps? All there? All the hardware nice and rust free?
