My 98 disco with a 4.6

What's the point of your post Pacopico?
Does anyone build a Disco to drag race? You want serious horsepower in a disco? Build a crate engine and adapt it to fit with a painless ECM setup. You want a easy same platform upgrade? Toss in a 4.6.
My point is a comparative analysis of the power achieved with a 4.6 swap from the original 4.0.
Acceleration tests are a good measuring stick for real-world performance results post-swap, as acceleration is a measure of power generated/applied over time. Better acceleration can indicate better performance in deep sand, mud, loose shale, deep snow type terrains.
If you think I was intending to build a drag car, think again. My final point was to illustrate that relative to modern over-the-road conveyances a 4.6 swapped Disco is still SLOWER than a econo-box.

On stock tires is where it makes the difference. Regear your truck to 4.1, then come back to us with acceleration data.
Most people that do the 4.6 upgrade is for 1. slightly better fuel economy, 2. not having to drop into granny gear to climb a 13% grade.
when this engine was in my p38, it would keep up with N/A RR sports.

I did the swap as the original 4.0 liners were well worn...found it cheaper to swap the used 4.6 than to rebuild complete.
No fuel economy gain or penalty on this end, and it does run up grades slightly faster.
Gears do make a difference, though we are still dealing with warmed over 60's technology here.
