1986 Ford Mustang Convertible


You can get an 8.8 with an lsd from a ford exploder.


i certainly do NOT want one of those


So it’s from the Pinto?


my mums mum had a Foxbody but it was the i4 coupe 1983, apparently it was terrible.

I should probably give an update on this.

I’ll write it later, when I have all the pics gathered on imgur.


I’m sure a grandmother knows a lot about how to review cars :laughing:

Update: Engine almost finished, and new rims!
As usual with any project, you underestimate how much time it takes, and how much money…

My dad got me those rims for $200 with almost brand new tires on them!

Starting shape

Almost buttoned up

I still have to do the valves on the 1969 heads I have, but otherwise the engine is nearly complete!

Reference shot I took of the carb while rebuilding the primaries

That’s a Holley 600cfm 4-bbl with vacuum secondaries. It’ll make my engine just purr. But it had been sitting for over 17 years, so I was sorely in need of a rebuild.


Welcome back from your break! :innocent:

Did you not say there were 1968s?


Before I got them cleaned up, I thought they were, as that’s what my dad seemed to remember, but upon a good de-greasing (and later cleaning by the local machine shop) the stamped part number was much clearer
C90E which C9 means 69.

I also got some screw-in rocker studs put on.

It’s still the same specs we were expecting. 58cc chambers and 1.8" intake valves 1.5" exhaust valves.


Bought this little book at the summer nats just because


You really need to find one of the big maintenance manuals. Those things are extremely helpful.


I do have a Haynes repair manual for it. As for the 1986 dealership manual, The booth had it, but I couldn’t justify the cost.

I also got myself some valve covers with matching breathers, and matching air cleaner among other stuff at the summer nats. Once I get the valve covers clear coated, I’ll post some pics.


Update: Heads need to be completely redone. I was checking the valve guides myself at home (wiggle valve in them basically), and without actually measuring them, I could tell they were bad and the exhaust valves were deeply pitted, so I got them back to my machinist.

I was hoping this wouldn’t be the case, but all the valves, valve guides, and seats need to be redone.
So, 16 new valves, valve guides, and hardened seats are going on the heads… For about $550

:stuck_out_tongue: Engine building costs :stuck_out_tongue:


I really like foxbodies for no apparent reason, but 120hp? really? I mean I know about the “no power” in the 80’s but I never thought it was that bad.


That’s not the worst engine though.

If you got the standard i4, you had only 88ish hp :joy:


So… Long time no post.

It’s a mock-up and to protect from dust and stuff

But finally some reasonable progress to post about!

The Good:

  • Heads are done and now installed
  • Got new valve springs and caps to match the cam.
  • Cam Specs Here for those interested
  • Everything was painted Ford Blue
  • My camera actually took a good photo
  • Got Smithy’s Mufflers for the Super Retro Sound
  • Got new trans cross-member as well as sub-frame connectors
  • And lots of other little things I’m forgetting right now…

The In-Progress:

  • Have (almost) all the pieces to put the engine all back together
  • Pretty valve covers are pretty (but still need a clear coat)
  • Pretty Rims are still Pretty
  • I had some time to actually do stuff
  • I have a C4 transmission and 8.8 Rear End with a Traction Lock (Ford’s name for their lsd)

The Bad:

  • Rockers are completely worn out, I’m buying new ones now.
  • New Rockers cost money, many money
  • Still need an exhaust system
  • more stuff I can’t think of right now.

So yeah, now that I’ve got some time as schools done (I’ve graduated with an Associates Degree) and I havn’t been scheduled many hours yet (YET) I got some time to finish up the Mustang! …or run out of money trying.
