my block is a 53 block thats perfectly good, but still im concerned. all i hear on line is horror stories. i bought the truck a year ago as a project truck and have been saving money for transmission and performance stuff. my question is, is it worth putting the money into it or should i dump it and find another truck? it has 160k mi on it. anyone on this site have any problems with a 53 block? or have you had good luck with it? or am i just worried over nothing? any advice is appreciated thanks.
