5.0 engine question

[reddfox]

I was given a motor from a 87 thunderbird is this an H.O motor? Are there any differences in this motor and the one in my 89 LX?

What does it say on the plenum plate?

Based on what I remember, and this page:

I believe your t-bird motor is a non-HO engine. I'm pretty sure that means it has crappy heads (not E7's), and I'm not sure those engines came with roller cams.

Someone here will know better...

Being as the Super Coupes were the top of the line birds for power, and they were only putting out 190hp, I think the engine is a non-HO.

Do you mean turbo coupes? The turbo coupes put out 190hp towards the end of their life, the super coupes had 210-230hp depending on the year.

when i got the motor the intake was off. I have a set of e7 heads and an f-cam so if it is only the heads I can fix that.

If it's not a roller cam block, you can't easialy run a roller cam in it. I think there are retrofit kits, but I believe the non-roller blocks aren't tapped for the spiders that hold the roller lifters down.

If I remember correctly, the thunderbirds used a non-H.O engine but it is a roller block. The cam is different for these because of the different firing order. Also, as stated above, the heads are crappier than the E7's. I'm not sure if the internals are any different than the H.O's or not though. Do you plan on rebuilding or just throwing the cam and heads on it?

 

[reddfox]

I learned that it is not an H.O motor. Can I use the F cam and just change the firing order to an H.O or do I neeed a new cam. This is going to be a carb combo so no computer

 

[bullitstang1313]

Yes you can use the f-cam. You will want new hydraulic roller lifters as well as it is best to replace them when you add a new cam. You will probably want to run different heads though since the non-H.O. heads were more restrictive.

Do a little searching around on this forum...i feel like i have seena thread much like this a little while ago. A guy put a carb on a non-HO motor. Even if its non-HO i think its still a roller motor. I think there is a kit out there including the proper valvetrain components.
