Currently have a 302 with a M5R2 transmission in a 83 F100. Engine needs rebuilt/replaced. I found a 302 with a T5 transmission attached. Should I swap it all or stick with my M5R2? Truck is used for weekend driving. Never pulled a trailer.
I don't know anything about a T5, but found a thread on it here: https://www.ford-trucks.com/forums/7...-t5z-swap.html. Some things to think about pointed out there, like drive shaft length, clutch linkage, and shifter placement.
Good idea, it's a truck transmission and not one designed for a sports car.
The T5 was used in the Mustangs, here is what my sister's looked like after too much abuse at the drag strip:
Was that a WC T5?
Did she have a positive stop after market shifter installed?
Also 5th gear billet bearing retainer installed?
The shifter is the big one as you over throw the gears and bend the shifting forks. Then the next gear it moves does not engage all the way and you end up with what you see in the pictures.
There are other little things like replacing the plastic fingers on the shift forks with billet ones and billet cluster (1-2 / 3-4) keys as the stamped metal ones will bend.
I rebuilt WC T5 with all the goodies above + to run behind my AMC 360 v8 and did not want it to fail.
As for the T5 in anything other than what it came in and the shifter lining up where it needs to be is the biggest thing to work around. They say you can use an S10 tail housing but the speedo cable is in a different place and does not line up with the gear on the output shaft and it is not easy to fix this.

No idea, she farmed out the job to one of her racing buddies.

Everything was stock, she replaces things as she breaks them. IIRC she had a Tremec sumthin-or-other installed which required re-gearing the rear end.
EDIT: My brother tells me it has some sort of "Hurst limited" shifter, apparently on her second one of those.
She's also beefed up the axles (after having broken at least one).

Apparently, it was third gear that suffered the most damage.

I took some videos of her about two weekends ago (she is on the inside lane on both) below are Rounds 2 & 3 of the Stickshift class at Bandimere Speedway in Morrison, CO. She made it ALL THE WAY TO THE FINALS!!!! Lost that one but that's OK, I'm still proud of her, I taught her how to drive a stick shift in my father's Corvette when she was 14-15 yo.
These videos have been really shrunken by Facebook, sorry about that.
It looked like she was running brackets with a dial in of 15.xx if ai saw it right.
Brackets with that dial in most of the time is a full tree.
My street car I started racing was 16.0 - 16.50 my drag car was 13.0 - 13.5 both depend on out side temp & track I was running at. Most of the tracks I ran at were 2+ hours away when I lived in CT. All were 1/4 mile down here 1/8 mile is big but don't see why?
As she found out drag racing a stick car is hard on parts. I went auto because of that but also upgraded ever thing on the drag car when building it.
No problem on the hijack, the OP hasn't been back since yesterday morning, I think he got his answer and left.
OK, I talked to my sister this morning; there is a LOT more to this stuff than one would imagine!
Yes, apparently, this is bracket racing (something termed ET? don't remember) she is typically the slowest in her class at 15.xx in the quarter mile, she posts a time that she cannot beat else she'll lose the run. Figuring out what the next time will be is something of an involved process, I watched her do it.
My vantage point was from the halfway point, there is even a big, yellow stripe across the track to show that.
Yes, she's on her second Hurst positive-stop-thinger shifter; she's been doing this in this car since the early/mid 90s and broke an axle I guess about 10 years ago, the transmission breaking was only about two years ago.
The trees, she went on & on about that... apparently she has done both Full & Pro Trees but spends most of her time on the non-pro variant (don't remember the details, I think it was something about the timing, or maybe one racer beginning before the other one on the premise they will "catch up and overtake" the frist).
Neither of us know what a WC T5 is.
OK, RT... Reaction Time...
.040
Whatever that's worth, you can tell I know very little about this. I was on an amateur track (not drag strip) about three years ago, my trainer (my first time there) was showing me all the stuff that is part of racing on a race track, apparently it's not much different on a drag strip....
So she does not go a little over her dial in ie: if car runs 15.50 dial in at 15.75 this way you have .25 in the bank to play with at the top end. Still need to be first at the finish line but not be faster than 15.75 so you back off or hit the brakes before the finish line. Being a slower car helps as I was the slower car most of the time.
Yes RT is everything! It can change on how deep you stage the car at the start tree and what light you leave on using a full tree. I have never run a pro tree (yet).
RT can also change with you with what you eat and how much sleep you get before racing. RT you need to be OCD! With my drag car I was running .20 and had a few .00 to earn by runs. Street car was about what your sister runs, bad leaf spring bushings.
Yea I was pretty deep into it when I was racing even with my street car. Kept drag log book (Summit Racing has a good one) where you note ever thing of each run and I mean every thing. This way if you only got 1 run before rounds I could look in the log for the track I was running, weather station OAT and knew what my car would run.
The other thing with brackets other than knowing who left first I never looked at the other racer till close to the finish line to see when I could back out of it as I dialed slower than the car could run. Run your race and you will be good.
Now I want to get my drag car running again! Just what I need another project!

I searched summit's site for this but couldn't find it; can you find al ink for it, please? Might make a good birthday/Christmas/whatever present.
This is another thing she went on & on about, what time to declare. She's apparently at least halfway decent at this stuff, has lots of trophies & awards in her house, she even won overall first place in her class a few years ago.
