What year HO?

I am going to swap an HO motor in to my 88 sport coupe and i know that mustangs switched to mass air after 88 but does that mean i have to find an 87 or 88 HO to use speed density or else convert to mass air with a 89 and up engine?  I have an HO speed density EEC already so i dont really want to convert to mass air right now but finding the right year engine may be a problem. Thanks

The year doesn't matter, a '93 HO will run just fine on '87-'88 Stang SD system.. As will a '88-'92 LSC Lincoln HO or a later Explorer 5.0.

I beleive mechanically all the engines are the same.

One thing you may look into is, I believe the <92 engines are 'forged' and the 92< are hyperwhatever (can't spell it)....

There. Everything you ever wanted to know about pistons.  :giggle:

The minor component being silicon. Which makes the piston very strong, but in the event of failure it will shatter rather than bend. I would stick with forged pistons if you had a choice.

Is there a way to tell if it is a early 92 or late 92 engine?(without looking at the car) I got a HO out of a 91 or 92 mustang(at first they said it was a 91 but on my reciept they wrote 92) with 87000 miles on it for $400. It doesnt really matter i guess if it is forged or not. The car was basically destroyed from the firewall back, from the accident it was in.

Look at the casting date on the passenger side of the block in the starter area.

The date will be a 3 or 4 digit alpha numeric code, with 1M1 decoding as Dec 1 '91 and a 2A11 being Jan 11 '92. Get the date and I'll decode it. This won't tell you when the engine was actually assembled, but usually it is within 2-3 weeks.
