ford 351m/400
Well guys I need help. I just got a 1976 f-150 ranger xlt 4x4 nice all around it's an eye catcher. The org. owner died old lady kept it for a few years since 2001.ffice:office" /><O:p></O:p>
Well the guy did some work on it but the old lady didn't know what. She did say that he had changed the eng. but to what she did not know. Well to make a long story I got it for $800.<O:p></O:p>
<O:p></O:p>
The truck has a 351m/400 indicated by the casting #, off. Aluminum intake dual port, 600 cfm Holley carb new I just got it 2 weeks ago.<O:p></O:p>
<O:p></O:p>
Now the problem starts up fine with good oil pressure but when the truck heats up to operating temp. The oil pressure goes down more than I like. Then the truck starts to run a little hot. two days ago the truck started sounding like **** I think that due to the fact that it was running hot it fouled up the plugs. Also checked the timing and it was about 30 advanced so I moved it back to about 12 since I do not have the right specs.<O:p></O:p>
<O:p></O:p>
Can you all help.<O:p></O:p>
