PI Heads and Intake

[Grandmarchris]

Im wanting to put PI heads and intake on my 92' M75..Its a old romeo built engine..Just wanting to know if its do-able...If not....Time to do a 5.4 swap

Not worth the time and money. You can find 2001+ engines with low miles for cheaper than what it would have cost to do the conversion. However you might have tranny fitment issues.

Its just new heads and Intake....I was thinking of getting all of it from the junk yard off a mustang or a 01+ vic

If you do a 5.4 swap does the AOD hook up to it? If not, what trans do you plan to run?

[DuceAnAHalf]

The only way to run a AOD behind a 4.6 is to use a 91 or early 92 block with the AOD bellhousing bolt pattern. You cant run a 5.4 with an AOD since there are no 5.4 blocks that bolt to an AOD. You could run a newer AODE/ 4R70W behind either a 4.6 or a 5.4 if you get the proper trans/computer.

When I said AOD I meant the stock trans in his car. I thought it was an AOD like the boxes have. What do Areos and whales use, just a regular 4 speed auto?

First half of 92 used the AOD, mid 92-Mid 96 used the AODE, Mid 96+ uses the 4R70W.

Mines AODE it was built on 7-92

In that case it should be the normal 4.6 bellhousing so you can use whatever mod motor you want

[Mr. Land Yacht]

if you can go for the 5.4, then do it!
don't bother with a "Performance Impaired" 4.6 motor...LOL J/K

[88Vic]

I don't think the DOHC 4.6's are performance impared. They have some balls to them, even in N/A form.

[p71towny]

They do, but stuffing them in a pre 03 panther is a whore.
