thanks
i have a stock 454 block ( 512 casting)..came out of 69/70 chevelle's..its a 4.375 bore (.125 over) and a 4.25 stroke...511ci or some say 512ci..
Many say you cannot bore one this much but i am proving this theory wrong..Block has been .125 over since 1997..i have had it 3 yrs its been refreshen and i run the piss out of it..gas and alcohol..
i have also heard that the (512) casting is a little more beefy than some other castings...i don't know about that...some of the guru's on here can enlighten on this subject....check your castings on that motor before paying him..
so yes..the stock 454 block can be a 496ci no problem..and bigger.
