Hi all,
I've been doing some reading and I'd like to get some good advice on what to do
. I have a '95 F-150 with the 5.0 Truck firing order (15426378)
(I know this is a BBF forum but you guys mean business and you really know your Ford engines) and I've been told that the 5.0 HO firing order (13726548) is worth some horsepower. I also heard that it is better for engine longevity (but the explanation for this wasn't totally convincing). Any thoughts or theory about this would be really appreciated?
I realize I'd have to change to a cam that is made for the HO firing order. Does the HO firing order have anything to do with exhaust gas pulses (similar to the reason Ford did the crazy "bundle of snakes" headers for their GT40 in the 60's)? Would keeping my stock type single pipe exhaust setup negate any gains to be had from changing the firing order (the only difference in my exhaust setup is a 3" in/out Hushpower Pro muffler and 3" piping? Even if there's only a small improvement I'd be interested in trying out the switch.
