 428SCJ shortblock -- Jeff H., 09/11/2005
The 428SCJ engine that I pulled out of my 69 mach has been sitting on a stand in my Uncle's shop for several years now. For my resto I have collected several engine parts (including NOS 428CJ block) and was planning on parting out this engine (not orignal to car) and selling all of the parts. So my father calls me last night saying that a friend of his has been asking him if I will sell him some of my 428 parts for a shortblock for his '67 eleanor project. I decided that if he agreed to a fair market value price I would tear this motor down to short block and sell to him. I would appreciate it if you guys could help me establish this asking price I have listed all of the details below.

428CJ block fresh .030 over (partial VIN indicates it came from '69 fairlane) with oiling mods, C scatch rear face, less than 2,000 miles since block was overbored
428SCJ (IUA) Crankshaft fresh re-cut .010/.010
428SCJ Lemans rods
Fresh .030 over 428CJ flat top pistons
stock 428CJ/390GT cam
SCJ hatchet c'weight
428SCJ/427 balancer
SCJ 4 speed flywheel
Entire rotating assy balanced
Stock 428CJ pan
428CJ windage tray

An FE 332, which is a member of the bigblock family, has none of those attributes when compared to a 351W -a member of the smallblock family.

There is also no logical correlation between displacement and redline. Many smallblocks are all done at 4,500 and many bigblocks are just starting to come to life at this rpm. This is a function of purpose rather than casting molds.

The distinction between what is a smallblock and what is a bigblock is very arbitrary at best since the factories never made these classifications. These definitions were made in aftermarket nomenclature and in bench racing.

Some examples are quite obvious. A Ford 302 being a smallblock and a 460 being a bigblock. But how do you define a 326 Pontiac as compared to a 455 Pontiac? Both are idential extenally and weigh the same. Is a 400 Chevy a bigblock and a 396 a smallblock? And if you bore and stroke a 351W out to 427, did you change it to a bigblock?

It's always best to refer to engine families rather than the vague notion of arbitrary classification rooted in the mind.

You are right in many regards, but not in absolutes.

 theory of relativity? -- John, 09/14/2005
I thought it meant that a small block was smaller than a big block and a big block was bigger than a small block. And since there are different families of big blocks for example, the "smaller" and "bigger" referred to significant size diferences. All relative you see. Ah heck.....I dont' really know, but I know them apart when I see them.

 T10 Speedometer Problem -- Dunk Campbell, 09/07/2005
We are having a problem with a Borg Warner H1 T10 4 speed transmission. We were told that it was from a 1966 Mustang.

We have installed it in a 1966 Mustang coupe, that formerly had a 3 speed installed. The transmission fits and operates fine, but ...

We have no speedometer operation.

We had installed a new speedometer cable and driven gear, and removed it from the transmission. The speedometer needle deflects when we spin the driven gear on the new cable. We can see the internal speedometer drive gear, and it is turning when the transmission is in gear. We suspect that the problem is that the driven gear is not meshing with the internal speedometer drive gear. The driven gear is about as large as possible to still fit into the transmission, so we think the drive gear is undersized.

We removed the internal drive gear, and find it is white nylon, 6 tooth, with an ID of approximately 1.25", and an OD of approximately 1.925".

We have found replacement T10 four speed drive gears in various Mustang parts house catalogs, but they all have an ID of 1 - 3/8", which leads us to believe that this might be a Falcon Borg Warner T10 transmission.

Anyone have any ideas where we can locate a correct speedometer drive/driven gear combination for this transmission?

tko 500 or 600 only way to go, the 3550 is hard to get parts for now and the t56 you have to pay big $ for to get the higher torq. version. You can get 2 different final drive ratios. 1st gear is lower in a 5 spd tremec than a top loader so you can start with bigger tires or higher gears
 RE: 5-speed conversion for 69 Mach 1 428CJ ?? -- Tony P., 09/06/2005
The above post mentioned a good point. Torque! Watch out, you get what you pay for. The lighter duty tranny might work just fine for normal operation, but if you launch it hard and it hooks up, the torque from the mighty FE428 will leave the tranny's guts on the ground. Just speaking from experience.

 Gear Vendors Overdrive -- Dano, 09/08/2005
It may be cheaper for you to try out one of the Gear Vendors overdrive units, they make them for toploader Mustangs, unfortunatly, I don't think anyone here has any experience with this unit. But it couldn't hurt to check it out. The big blocks fit so tight in Mustangs, changing things like clutch and shifter linkages really doesn't leave much room for error on th aftermarket 5 speed kits.

Then the transmission mount has to be moved up and back, or you can fabricate an adapter.  Dark Horse may have a different cross member or adapter.  The shifter was in a different location than my top loader.  There are 2 different 1st gear ratios and 2 different OD ratios.  With all the torque of the 428, I'd use the higher first gear.  OD depends on the car and how you use it.  If it has a radical cam, then I would go with the .83 OD.  If you want an easy cruising gear, then use the .68 OD.  I have the .83 gear and I love it. </blockquote> RE: 5-speed conversion for 69 Mach 1 428CJ ?? -- Cobra428, 09/13/2005
I have a 428CJ in a Cobra kit car. I converted from a top-loader to a Tremec 5 speed. The input shaft has to be cut down on the Tremec (Dark Horse can do this for you) or you have to add an adapter plate.

been there done that,got the T-Shirt.....Call McLeod industries and ask for "RED" I forget the P/N but they make at top loader to T-5 adapter that has the correct front bearing retainer I.D./O.D. to fit, all you have to do is drill the threaded holes to pass thru size. Also have McLeod build you a 11.5" reverse hub 26 spline disc, not anymore expensive then a 10 spline, and you are not taking the tranny apart. Order up a crossmember from Ron Morris Performance and bolt it in! There are two choices for the driveshaft fit....shorten the shaft or get a Bronco/Truck yoke for the 9 inch rear(I used the yoke) I installed this set-up in my 69 CJ XR-7......3.25 gears 26" dia tires .64 O/D ratio yields....70 mph=1800 rpm 2500 rpm=100 mph. I used the TREMEC 600 purchase it from Mustang Racing Technologies ask for Scott. he flat rated shipping for me and was not marking up the tranny. I spoke to a few places that had""KITS" and offered shortened input shafts and some other fluff and the conversion will be 700-1000 bucks more. The adapter is FINE if you want send me an e-mail and I can fwd some pics of my install. I installed Pwr R&P after the last CJ smoked and I have about 2K miles on the car w/5spd and pwr rack...IT ROCKS!

Oh and the shifter will be centered in the tunnel you will have to open the factory shift plate in a small crescent shape and the tower will be almost perfect. There are about 50 Hurst shifter handles you can choose and they bolt right up to the 600 stub. I welded a factory handle to a small adapter drilled 2 holes and found a 70's NOS aftermarket leather wrapped shift handle with the Cougar emblem and it looks GREAT. used the factory Z bar mechanical linkage with the factory three finger pressure plate and clutch pedal effort is equal to my Dads Camry!

I use a Richmond Gear 5-speed and am very happy with it.....I use a 3.07 diff. First gear might benefit from a lower gear (an option when you order). Good to 600hp I hear and fairly cheap....bought mine through Summitt. BUT.....you'll probably be on your own to figure out how to handle the installation in the Mustang....shifting linkages, etc. Maybe call Richmond and ask them?
