I'm putting my old 4.8 in the Monte Carlo. Bone stock bottom, seen 22psi before...going to 30 after its installed lol. Don't really care if it blows. Just curious how far the thing will go

Also swapping to the 4.8, I plan on running 20+ as well, I know a few others that have no problems running this on a stock motor
