hello friends of buick,i reccently had a 69 lesabre 350 rebuilt and put in my 71 skylark i have had nothing but problems from low oil pressure even after rebuilding the oil pump.i switched out the point to HEI,and i still have no power,installled a low end high torque cam,and i totally dont know what to do,i figured i would get more horsepower from that motor since it came with 280 horse's from factory.:confused:
