What year model did the 5.0 start with roller cam?

My local parts yard has an 84 Lincoln (Town Car, I think) with a 5.0 in it, with a metal plate that says 5.0 EFI (and something else). Is this a roller cam motor?

Is $150 a good price for a non-running motor, and is $250 a good price for one that runs?

He has quite a selection of motors, just want to figure out which one has the roller cam before I buy, and make sure the price is good.

Got a working electric fan and shroud for $25 ...gonna lose that extra fan belt and fan.

What horsepower will the electric fan give me, after I take off the stock fan?

 

Mustangs started in 1985 ... I'd would try to get one out of a Mustang so you know it is an HO engine ....

 

Ain't the junkyard fun? When I got to the junkyard, I feel like a little kid in Toys R Us.

 

What about the Bronco with the GT7P heads? What year did that start?

Would I be better off with the Mustang HO, then find the heads off the bronco, or does the Bronco have the same motor?

 

Isn't it funny how excited we get at the junkyards? I'm the same way. I get sensory overload.

The non-H.O. 5.0L engines have milder cam profiles, even though they're roller. I wouldn't waste my time with it unless it's an H.O. ...

 

SOME of the lincolns, mercs, and full-size Fords had rollers in '84...not many though. Same thing carried over to '85, some were roller, some were flat-tappet. I pulled a motor out of a '84 Grand Marquis...it was a roller. Pulled a motor from an '85 Grand Marquis not long after, it was flat-tappet...though it was drilled and tapped for the roller cam.

Best bet it to pull the intake and take a look-see. Either that or pull a valve cover and measure the length of a pushrod. Roller pushrods are very short (6.25" long IIRC)

 

I actually know something about this,The difference between GT40, and GT40P heads, is the P heads have an angled spark plug and have a F77E casting #, and the 40 head is phisically identical to the E7TE HO head, but has 1.84 intake, and 1.54 valves and a larger intake port, and a 4cc smaller chamber,(60cc),and a F3ZE casting#, the P head has 1.84, 1.46 valves and you can not buy headers for them to fit any early fords, but the 40 head fits everything, they came on 93,94, and 95, cobra mustangs, 96 explorers, and 95-lightnings, qwick identification is 3 vertical lines casted on the front of the head, and the 40P's have 4

 

non HO blocks

The non HO roller cams are ground with the 302 firing order while the HO cams are 351W firing order. Stock HO cams are very inexpensive so converting the non HO to an HO is simply a cam change. Try corral.net, you may be able to get someone to give you one. I bought a 93 30,000 mile cobra EFI computer, cam, lifters, mass air meter and timing chain for 80 dollars from a corral member. Be careful with the lincolns as those pistons do not have valve reliefs meaning you can't run higher lift cams (stock HO is OK). If you were to use the EFI then there are some additional issues with the wiring and intake design. Remember, when using the roller cams you need to use a different gear for the distributor!

 

Yeah, "40P" was what I meant. You guys knew that.

Are those few models the only that had the GT40 heads?

I thought the 40P heads could take our headers, but needed shorter spark plugs. Am I wrong on this?

 

good head flow data

this is an excellent site for head flow info

and here is the cam data for HO roller motors

Fletch has a great site!

 

Can I make this easier (on me) and ask...

What car(S) do I want to yank the engine from?

 

I'm not sure but isn't it the 86 that didn't have valve reliefs? not just lincoln but most 86's? Also, were there other GT40 equipped vehicles? when I sent my F3ZE's out to be ported the machinist claimed they came from a 351W powered truck even though I told him Z in the casting meant Mustang. He said they were the same but had bigger chambers, like 68 instead of 60. some headers will work with P's with the shorty Accel plugs but when I checked they were like 13-$14 each. how often do you change yours?

 

I too fell into the dreded roller motor trap, I bought two different engines (supposed rollers) and found out they were both flat tappet engines . The first was out of a Lincoln and the second was out of an even newer truck. Got ripped on both of these. So i got one from a late model mustang GT and finally got what I wanted. The flat tappet motors didnt go to waste tho. Just threw in a solid lift flat tappet and threw it in the 1/8 mile car. CHEAP FUN!!! The best way to find out is to pull the intake and have a look see as stated earlier. good luck..

 

Roller motor are cool

 

My advice here: ALWAYS ask the cam manufacturer what dist gear to use. I made the assumption as has been mentioned, that the cast dist gear would not work and to use a bronze or steel gear. Well, after wearing out a bronze gear in a couple thousand miles, I called Comp Cams, and they told me I needed to use a cast iron gear with my roller cam, because it was not made from a billet core.
