Well its a 350 it dosent have a TON of miles but its not brand new either. Well im wondering if its gonna blow up because ill be crusing down the road at a even rpm and the eninge will start to cut out then go cut go cut go some times it will do it for a wile some times just a few times it also did it last time I went up a steep bridge. I looked at the oil pressure gauge when it happended to day and was fine but im not sure if it really works 100%. Any help would be appriciated. BTW I want to keep it a 350 I dont want to bore so what im I looking at for a rebuild? pistions and rings? anything else? I was told you can pull out the pistions though the bottom of the engine (after the oil pan removed) Also someone told me it could be a fuel pump???
