87 mustang Stocker - help me not get laughed off the track!

I was wrong. By the end of that abbreviated 1rst season, I had 2 broken/damaged T5s. For the next year, I bucked up for a used Jerico DR4, and a used McLeod Soft Lok clutch assembly, which I had rebuilt by McLeod. 10 seasons later, the Jerico is still untouched, even with my mid 10 second bracket engine in the car the past 1 1/2 years.. Good used T5s are worth a few hundreds bucks each, busted ones, next to nothing.

That's interesting - do you know why it didn't last once you started racing but was fine before?

I do have a spare that I was planning on rebuilding with G force internals. Supposedly they are good for 450 ftlbs but I've heard mixed things.

Thx for the input - ill look for ways to upgrade the trans/clutch

As others have stated. Your throwing money away on the T-5. My modified crash box lasted longer than it should have but when it went it was all junk. If it means saving money it will be money well spent, a used Jerico, or G-Force. Call G-Force, they sell rebuilt trade-ins at a reduced cost over new ones. They are not cheap but it will be bullet proof. These BTW are a GF-4A or a GF-5R. Also the clutch is what is going to kill the T-5, as it is an On/Off clutch. Do not buy an over the counter or mailorder clutch. You will not get the correct clutch for a Stocker if you do.

As for the engine. My original junk shortblock with a budget rebuild and stock rods with stock rod bolts is still in one piece and it saw lots of 6000-7000 rpm passes. I always thought it would be the weak link and not the T-5. It is my spare but would not hold a candle to the current engine.

I may be a little apprehensive that if you do just a stocker cam and a valve job on the heads you will get it to run index. You won't know until you try. But if so that would be cool.

From the sounds of your interior, that needs to follow the rules. It has to be a full interior minus the backseat if you have a rollbar. Before diving into this, read the rule book. What is allowed and what is not is very important. Attend a National Open, divisional, S/SS race, and ask questions, hang out and watch tech, and what they are doing. This is a very rules restricted class so it is important that you are aware of what is required in order to play. Everyone here and at the track in our class are the best people and will help in any way, so jump in and we will help if possible.

BTW if you add your name it will give you credibility, and not just another person standing behind a screen name. It will allow more conversation and willingness for people to help you.

Hope this helps

sean - great points thanks. also thanks to the others, all have added very good value.

i will add my name - i'll have to figure out how to change that - my log in is the same i use for everything so its easy to remember

i bought an NHRA membership and ordered the rule book, i tried looking at the online version and am either too dumb to figure out how to access or the website has some issues right now. Hopefully that shows soon.

i'm not too far from Gforce in PA so i'll see if i can budget a good unit from the get go. i do have a spare t5 that has a bad 3rd gear i coudl get built. May need to sell off some other parts first. Know anyone that needs a Dart 8.2 block and some AFR 185's? . . .

looks like i'll need to rethink the clutch too. I'll be working on this over the winter so i'll def post some pics and updates, probably in the "build" section.

thanks for all the pointers. It is MUCH appreciated.

The Astro A5 sounds like a good trans. I'm going to try one in my '87. It's been discussed a lot on The Corral.

i've looked at those as well. they seem to be stronger than the gforce t5 kits and to be fair the gforce trans are marketed as "street". it seems that they still have 3rd gear failures.

If you end up going this route i'd love to hear any feedback. I'm going to start on the motor now and hope to have some cash together to deal with trans and clutch before spring. Before i pull the trigger i'll talk to the guys at gforce and Astro, and am leaning towards a Ram sintered clutch/alum flywheel setup (about $1500).

Trans and clutch should be right aroud 4500 which is still "budget" compared to the the G5r approach.

One other item not mentioned IF your planning on running Stock Eliminator
is you will need to put door panel/headliner/back panels back in the car.

If only running in brackets then no interior needed.

May need to upgrade the roll bar to 8 point and a 5 point harness.

Enjoy your project and just watch your expenses.

Launching a street car at 3000 RPM is a lot different than leaving at 5500-6000RPM. Twisted the mainshaft on 1 trans, broke a main case on the other, also had a slider pile up on the hub. If you retain the stock mainshaft, that is a weak li9nk, regardless on how much HP the trans shop says the gears are good to.
