Hello this is my first post here, I did a search for this information and couldn't find any definitive information on the topic.
I just purchased a 1995 E150 with the 5.8 L 351 V8.
The pre-purchase inspection found a small leak somewhere in the exhaust manifold warranting replacement of the manifold.
Most of the online information for these motors is within the hot-rod/ muscle-car community, and is influencing me to approach this fix as an opportunity to upgrade the headers and exhaust to allow the engine to breathe a bit better.
Although all the information I find is focused on total-raw horsepower, not necessarily drivability and low-end torque that will improve the dynamics of my van and even add some MPG.
My questions for those of you in know are:
Is this a worthwhile upgrade for improving power and driving dynamics of a 4x4 Van?
Please help me understand "shorty headers" vs "long tube headers"?
Will any of the aftermarket offerings even fit within the engine-bay and chassis of the 1995 E-150?
Thanks in advance for any advice or information!
