hey i recenly added a 1989 ford 250 4x4 with a 351 5spd to my collection of fords , it seems to have no power,, i have had a lot of 302s that were twice as powerful so i am tring to figure this out. it starts and runs great and has no blow by or smoke and the cat is gone and engine is tuned up (wires plugs cap rotor) and it is a 10deg timing with the jumper pulled. any recomendtions. also rear main is bad and at high rpm oil comes out , not sure if related but figured id mention everything

 

Not an expert but I think, if it was me, I would fit a new fuel filter and maybe check the fuel pressure.
Maybe also check for trouble codes, even if no light on.

 

sounds good anyone happen to know what the presure should be and maybe a quick run down on how to check codes on a obd1 thanks

 

Ford Fuel Injection » How To Run a Self-Test Here is a link on how to check for trouble codes.
I think fuel pressure should be around 34psi with engine at idle.

 

thats awesome thanks ill have to go buy a pressure tester and check codes

 

so i jumped the sti plug to ground and the engine revved quickly and had the power it should as if the timing advance was working so can anyone shed some light on this situation

 

ok after checking the codes and going through everything , its getting a carb put on it and a new distributer
