i will try and make this short. i have a cobra with a 460 out of a donor 73 tbird ( i think ) i did not build it. it was finished in 03, i bought last year ( 9/09 )...700 miles on it in 6 years.
first month i had it, it sheard the cam pin, i replaced that. when running again oil pump went out ( believe it was hi volume/hi pressure ) replaced with stock. it had been running ok, with a myriad of other problems, but oil pressure was not one of them...until recently the oil pressure has been dropping....replaced push rods and lifters a few weeks ago, but oil pressure continues to be low now..20 while driving and 10 at stop signs....i drained oil and added straight 40 weight...that helped keep it there....mechanic ( who did up top work ) says its probably bearings down below...i am starting with installing a new hi pressure oil pump vs pulling engine yet...see if that helps....( did i mention i AM NOT a mechanic, but slowly becoming one at this rate. anyone have any other cost efficient ideas before i pull the engine and do an over haul ? if i havent give specific info please ask.
thanks very much.
