Exhaust valve size 1.42"
Rod length = 5.7"
Intake port size = ?
Exhaust port size = ?
Intake manifold = open plenum
Intake runners = tapered?

Been srewing aroung with the program...

My raw torque and horsepower numbers for a 3.4L were 265 ft/lbs and 245 horsepower with a 208/206 cam with .450/.420. The headers are so efficient that exhuast needs to reduced to get a 75-80% intake/exhuast flow ratio. I set the headers at 30 inches with 1.5 inch primaries. Intake manifold is custom split plenum with 11 inch runners merged straight into the head and a dual 1000 cfm throttle body. Not bad for such a small cam. The runners measured 1.7 inches. Anything I'm missing except a reality check?
