Ok I've had enough of the worrying about my oil pressure I have a 350 that was in my shoebox when I bought that was built right from what I can tell and all the people that I have talked to say the previous owner was an awesome mechanic he is p***ed away so I cant ask what all was done to the motor. Hear say was that its bored over .30 . It has aluminum heads edelbrock intake carb 650cfm its suppose to have a hv oil pump I can't drop the pan to see unless I pull the motor and if I'm going to do that I should rebuild it anyway the problem I have is that it drops off when the motor warms up at idle and when your on the gas its fine. So I need a good machine shop in the Fort Worth area thats not gonna screw me I've heard alot of people being told that they have problems with parts that theres no problem with I just need some honest people to deal with hope someone has some info on a good honest shop Thanks.
