What octane fuel are you running?
What was wrong with the 93 engine?
We can get rid of that detonation you are having
FYI I had a 96 OHV longblock in my 88 BII using a 93 PCM for 12 years, never any ping issues
I'm using just regular unleaded...same as I always used with the original engine. Even regular is damned expensive here in Washington State (still almost $3.50 a gallon!).
The 93 had very bad rocker wear...it would tap a good amount until it warmed up and eventually quit tapping. I pulled rockers and confirmed they were pretty well worn where they were contacting the valve stems.
I was in the middle of doing all the pricing of new valve train parts when this 97 motor with 120,000 miles popped up for a $100 with a 5 speed attached!! The guy was doing a 5.0 swap and needed to get rid of old stuff to make room in his garage.
I figured I couldn't go wrong at that price and did the swap. I've read many, many other threads where folks have swapped newer 4.0's in by doing exactly what I did...taking it down to basic long block and swapping exterior supporting stuff onto motor.
Don't get me wrong, it runs great...but I can hear that slight pinging every once in a while so I'm a bit concerned about long term health of motor if I leave it alone?
