At least i'm not the only one. I really don't want to go through the hassle of taking off the heads. 8 pounds would be ridiculous on a 408. I figure i'll be at ~600rwhp with 5 pounds. Hell, i should be over 500 with 2psi.

Even if that is the case I would only be able to run around 7-8psi max on pump gas if I'm lucky.
Stock internals: you shouldn't really go above 8psi is the norm. Hell you'll still net over 500whp |
