I have a na 12 valve detroit 353, im wondering how many pounds of boost it can handle with no mods, its running a generator head one size too big and the blower seems worn out so theres not enough pressure in the air box to keep the oil out, a turbo would keep positive pressure in the engine and slightly increase the output, but it could also blow the engine if the wastegate is set too high.

im gunning for 3-4psi, but its hard finding a wastegate actuator set low enough, 5-8psi actuators are easier to find, but i would prefer not to find out if thats too much by blowing the engine.
