Thanks to all for the compliments.....Have a little over a 1000 miles on it now..........it's a blast........people think its a Cobra...."What kind of kit is that?"  "Is that original?"   makes my day..................Taken it to a couple of car shows & watch people scratch there head as they walk around it.......Performance is awesome...had to upgrade to Drag radials to keep from spinning (Nitto NT555R 275/40-17).....hooks hard......unofficial times: 0-60 4.2 seconds......1/8 mile  8.5 @ 92 mph.....still tuning.........

Very nice,
But a couple of questions.

I see you have a T5 transmission.

From the gearset you stated with the 3.97 first gear.  Is this the transmission for Ford 2.3's rated at 240 ft Ibs?

1)  How has it held up?   You have some very fast times posted and you have a lot of tire stickiness.

2) Are you using a shifter relocator?  From the pictures of the cockpit the shifter appears to be a nice forward location, but the off body chassis picture shows the shifter location back kind of far.  If you are using a shifter relocator which one are you using?   And how do you like it?

I am thinking about a T5Z with a 302, warmed over a bit.  And I am only going to run 205/70's.  I want to hear from folks about their shifter relocation brands and their success with the shifters.   I thought about a TKO as it has multiple locations, but money, weight, and other issues mean I am trying to avoid it.   My engine will never overpower the TKO, but with the T5Z I will be over the rated torque.   But I am not going to be banging thru the gears very often.

regards,
Tork

Tork, I used a '97 Ford Explorer engine as the basis for my build specifically for the short front engine dress. The water pump, timing cover and front damper/pulley are the shortest Ford used on the Windsor 5.0. I spaced my crank pulley just 1/2" behind the steering rack, and with a standard T5 Mustang unit and a straight shifter, I am right where the old shift ball was. The original Triumph shifter base was closer to the firewall, but has a 5" bend (memory here, was it 5 or 3??). Take a look at the pictures in my project journal under Dennis' TR6.

I suspect since you seem to have your engine already installed - is that correct? Then you would have to use that as a start. Options are S-10, rare Astro van or custom tailshaft housings. Or the TKO, which was over my budget.

As to the 240 ft lb limit of the 4 cyl trans, it may be that it would live behind the V8 if you don't abuse it, but since you are going to the trouble, I would suggest a
T5 at least upgraded to the 300# rating.

One last comment, is that I have a 3.35 1st gear, a 3.54 R200, with 205X65-15 tires, and think my low gear is maybe a little too low. Starting in 2nd is pretty easy (hey, I drive an automatic most of the time!), and the 2.95 of the T5Z might be nice. I think I get 10 mph in 1st @ 1600 rpm, which gives ~ 37 mph a@ 6000. That's ok for a drag car I guess, but for me, I would like a little longer run before shifting. I have NO intention of ever doing a drop the clutch start, stop light drags are 20-25 and punch it for me!

Dennis,
I found your posting in the Project Journal section.  So I added/will add my questions there in the parallel thread.  

My question here was to Don's use of the T5 with the 3.97 first gear.  If it is holding up for him, then a T5Z will work for me.   His power and tires are well above what I have or plan.

Right now I have a 302 with an AOD.  Since I drive all automatics, I want a manual.

Tork:
Transmission is a T5 from a 5.0 Mustang.....may have gear ratios wrong
Engine/ Transmission are in same position in all pictures
No shifter relocation needed.
As to times:
Not official...done with stopwatch & apps.
About 350HP @ Crank...Shifting @ 6K RPM
These cars are very light and do not stress the driveline much.
Quick times are the result of a very stiff chassis, good tires & the rear suspension having the correct anti-squat geometry.
