5.0 engine from 95 GT

It looks like the search function is missing so I'll just make a post.

As you know from my past posts, I had some oil pressure issues and now am looking for a replacement motor. The current motor has a 289 block that came from a 64 Fairlane (according to the casting ID) mated to a C4 auto.

I know a guy with a 95 GT with 5.0 with 55,000 miles on it. He's planning on swapping in a stroked 351W so I told him that I may be interested in his old long block.

Here are my questions assumptions (please correct me if I'm wrong)

1. 64 289s had 5 bolt bell housing pattern while newer 289/302's have 6 bolt. Does that mean that I'll have to get a newer C4 to make it work or can the bell housing swapped or modded to make it work? How about the flex plate?

2. As far as I know, the 5.0 should bolt onto the stock motor mounts.

3. Can I reuse the intake for the 289 on the 5.0 or did they do something different with the heads?

4. Will I have to use an electric fuel pump or do those EFI 5.0's still have mounts for mechanical units?

5. I understand that the side oil dipstick tube needs to be blocked and I need to reuse the timing chain cover with the dipstick hole from the 289 to the 5.0.

6. Same thing with the oil pickup tube/screen.

Is there anything else that I'm missing here?

Swap out the bell housing and engine block plate. You can reuse your flex plate.

2. As far as I know, the 5.0 should bolt onto the stock motor mounts.

Yup.

3. Can I reuse the intake for the 289 on the 5.0 or did they do something different with the heads?

Yup.

You can either reuse the timing cover off the 289 (that is what I'm doing), or convert to an electric pump.

5. I understand that the side oil dipstick tube needs to be blocked and I need to reuse the timing chain cover with the dipstick hole from the 289 to the 5.0.

Yup. Or you can drill the EFI cover from the '95 if you choose to go with an electric fuel pump.

6. Same thing with the oil pickup tube/screen.

Reuse the pan and pickup tube off the 289.

Another suggestion: replace the timing chain.

One more thing. You will need to upgrade your distributor to use a steel gear for the roller cam.

Thanks for the info, 66P51GT. Now how much should I offer for the engine?

Are you going to be using the serpentine belt setup? If not, you will HAVE to bolt on the early-model timing chain cover. If you're using the serpentine belts, your SOL as for where to put a dip-stick. The 94-95 engines had different timing chain covers than the Fox body 5.0s did. There is no place to drill a hole. And if you change the timing chain cover to an early-model cover, you will have to get rid of the serpentine belt setup for a V-belt. Because, the reverse flow water-pump will not bolt onto the early timing chain cover.

If the deal happens, I'll most likely end up with the bare long block.

 

[66P51GT]

A bare longblock with no EFI, I'd expect to pay $100 - $200 depending on condition.

I paid $325 for a short block with a Crane 2031 cam, Cobra FMU, HO 5.0 Intake, Fuel Rails, all EFI sensors, fuel pump, aftermarket throttle Body, and 70mm mass air.

I payed $1500 for a complete, running, and modified EFI 5.0 with a T-5 tranny. I also got the cars full exhaust, and it's speakers too on that deal.

Here are couple more questions I forgot to ask...

Don't the newer 5.0s user a lighter damper? I currently have a 3 hold crank pulley.

Also, I found out that the 95 is actually a Cobra. Will it make a much of difference in the value of the long block?

$800 for the long block.
