wideglidejoe Joe that bore will fit in all these sizes 352, 360, 390, 391, and 410. Its depends on the stroke of the crank that ends up in there. If you go on the FE-forum, the dream team will have an answer for you quick. A sonic check will tell you who far you can bore it out and max cubic inches of motor you can get. A 445 motor is a great torque motor for a car 4.25 stroke and 4.05" bore. IMO just limit the rpms to 6,500 max. HV
oil pump with a 80 psi spring. Run it 1 quart over full. Will not hurt anything. Rick L.
