You either have a ton of driveline loss or you tested at high altitude. With what you listed you should already have more than your target rwhp. Strangled at the intake or exhaust maybe? You don't have one of those reverse flow mufflers they talk about on some of the other threads do you?

I am certainly no authority, but those numbers seem loew for your specs. I am sure some others on this forum have better input than I.

Yeah, I think you should be making more than that too. My only comment would be to switch to a roller cam with roller rockers/lifters. Maybe the carbs and intake are slowing you down too.
