There is a reason GM got rid of it!

Large bore engines of that era were filthy as far as emissions went.
That's why Ford went to a V-10, smaller bore lower emissions.
Technology was not all that great back them compared to today.
In its day the 8.1 was a good truck engine.
Why didn't the 8.1L have more power and get better gas mileage? 9.1:1 compression.
But then once again, I don't think the intention of this thread was to compare to old against the new.
Just to reminisce the old 8.1.
And why was it a filthy engine? It was because it was not an efficient engine! That's why they killed it.
Once again, emissions.
It could have been extremely efficient but emission regulations choked it.
