Offey duel port manifold for 390 good or bad

Wish you kids would quit throwing sand at each other...

Personally if you want more torque why not fab up something like the old Dodge 413's with the long ram intakes with the carbs over the valve covers. Pretty neat and they truely worked at low RPM. The drag racers shortened the intake tract to get the powerband pulses at higher RPM.

I stopped Sam I am is the one that keeps going.
I did read the whole intake comparo Last year and this year and no where did I find a Dual Port intake comparison. In the intake comparo. I agree on the V8 the Dual Port and the Offy 360 both were dog performers.

Offy went out of business in 1983. Alot of people have stockpiled the offy stuff but I don't know why. My Wiend 2-4v FE manifold pulled 21 more hp than Offy's 2 4V manifold even before we ported matched and cleaned them up.
