try adding some octane booster to the next tank see if it stops
I have installed countless 4.0 from 95+ trucks into gen I trucks, detonation has never been an issue even with 91-94 computers.
Did you do anything to the 97 block while it was out? Lower intake gasket? Oil pan?
That is a killer deal on a 97 ohv engine and trans!
I guess that's what I needed to hear...just some re-assurances that others have indeed installed the newer motors with older computers without burn downs.
I just got a little freaked out when I read that article quoting the "Ford Engineer".
I took it out again last night, put a fresh tank of gas in it and drove it quite a bit...didn't hear any pinging at all this time.
Perhaps I was a tad premature, or just hyper-sensitive to noises.
After all the work I did in one fell swoop on this truck (5 speed conversion, manual transfer case swap from electric, 97 motor, one piece rear driveshaft, newer steering box, new front coil springs, new shocks) I suppose I am just being a little extra tuned in to (and sensitive!) to noises.
Ill tell you though, that truck sure does pull nice and hard now with this newer motor in it....I love it!
