How long are those primaries from the head to the collector? 30-32" ? If so those are known as long tube headers and have a sweet spot tune point in the 5000-6000 RPM range and that's good for the 3.0 but 1 3/4" are a bit to large. Would have been better if 1 5/8" header.
But I'm most interested in the runner lengths.

Next stop, rent an engine hoist and get the engine off the engine stand, unite it with the transaxle and install the power unit into the car. |
