Absolutely possible. I would think it would need more shim than that but shruggy

Buddy of mine built a 440 many moons ago that only made 5 psi so he shimmed the pump up nearly solid. Still 5 psi. Discovered he forgot to put a plug back in and fixed it. Didn't take the shims out of the pump...

Fired it up and the Lee Eliminator oil filter came out from under the front of the car like a rocket with 7 quarts of Valvoline Racing 50 right behind it. He said it instantly pinned the Stewart Warner gauge.
