Just kinda curious while we are on this topic.. i have an 84 cougar 3.8 with the C3... how hard would it be to stick a manual 5 speed in it? im thinkin a floor mount clutch adjuster.  T5's are pretty easy to pick up depending on which vehicle i need it from.. so anyone have an idea?

I went by a machine shop this morning and the guy there said he should be able to rebalance a 3.8 flywheel to the 5.0 spec for ~$100. Now I need to scare up some flywheels. So...94-99/00 Mustang 3.8s have the same imbalance as 83-88 Tbird/Cougar 3.8s, correct?

We want UPDATES!!!

I still haven't gotten confimation the 94-99/00 3.8 flywheels have the same balance as my '87 3.8.
Also, are all 83-88 3.8 Tbird/Cougar flywheels balanced the same? I need to find a flywheel to balance to 50oz.

I'm still waiting for the junkyard to pull a flexplate for me. It has been 3+ weeks. Hopefully I can pick it up early this week.

Dropped by my local SVT dealer and picked up a 5.0 flywheel. Part #M-6375-B302. There were no flywheels at any of the local junkyards. Car-part found a $40 flywheel, but shipping was to be $25-30 and resurfacing is another $25. I paid $105 for the new one.


If only the junkyard would pull the '87 flexplate.  :rolleyes:

I'm glad to see someone is throwing this idea around.  I am thinking about doing the same thing, so I can have a drivetrain for a V8 later.  Emissions tests around here keep me from the V8 swap for a few more years.  However with the dual exhaust, a manual trans might be the best performance upgrade I can make.

Check this out:  http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33615&item=7970677757&rd=1&ssPageName=WDVW

A 3.8L engine from an F100 pickup from 1982.  It has some strange looking valve covers and a manual trans bell!  The site says 4 speed OD manual, which is probably an SROD like on the Mustangs from '79-83.  So then I looked at the almighty partsamerica site and sure enough, there is a flywheel you can buy to mate a manual to a 3.8.  Just get it ordered for an '82 F-100. 

So again what's the deal about the crank not being drilled for a pilot bearing?  I'm not aware of any changes from year to year.  Check:

You could probably order a pilot bearing for that truck and use it on your engine.  Then install your clutch & T5.

I thought you had saved the day when I saw that. If you look closer at partsamerica's site, you'll notice the flywheels are 164T. Fox 5.0 T5 bellhousings only work with 157T flywheels. D'oh.

I got my money back on the flexplate I "bought" but never received. (I drew the line at a month  :rolleyes:). I bought another one from a salvage yard located by car-part.com. It should arrive Wednesday.

This is an excellent thread. Have any of you wandered off into the Ranger with 3.0? Or better yet the 2.9/4.0? Those trucks had sticks in them. But everyone is wondering about the hole drilled out for the pilot bearing on the crank. I would research that first before anything.

The hole for the pilot bearing ain't a issue... It's there...

The issue with the 3.0 and 4.0 is that they are 60 degree V6's and use a Mazda manual trans behind them.  I think the bellhousing much like the C3/A4LD on those vehicles, which will not fix a small block pattern.

i noticed that partsamerica site says the manual 3.8 flywheel for an '82 truck is an "E8" part, which doesn't make any sense

Whatever the case, we still need a part number on that 3.8/manual bell housing.  Mustang and truck SROD's were a little different, so this site says:

http://www.motivegear.com/tech_info/tranny_guide/tranny_guide.html

But are the input shafts different sizes?  Will the truck bell clear under the firewall if it's a different part?

I may consider an SROD swap if my AOD will ever break.

I must have missed that. Now another question is what about a Lakewood bellhousing? They look a little bigger. Anyone try those or something similar?
