cracked block should i run hardblock or?
ok a buddy has a 454 block .060 over he had two sleevesinstalled and 400.00 later hbe finds a small crack at the bottom of one of the new sleeves . it goes from the sleeve tward to oil gallery at pan rail . he is still building it anyway. we sort of thought we should put some hard block in it and let it set up then run some k&w block seal. any help would be greatfull to prevent future problems...thank you
