LS6/T56 in a 1997 GMC

I have started this project and will probably pull the 305 tonight!

I plan on using Nelson for the harness.
-Do you recommend them for the tune also?

I guess I will leave the factory harness to run the gauges, cruise and what ever else.
-Is this the best way to do it?
-What did you guys do with the wires left over (like the old injector plug)?

Has anybody used shorty headers or Mid-length from Mac for a Camaro?

The truck came with a 5 speed, so I'm hoping the quick dis-connect from the clutch master cylinder will hook up to the T56 slave.

Please let me know your thoughts and opinions,

Kris

Leave all wires until you're 100% finished with the install and then cut the wire off back to the loom.

Order a PCM pre-programmed from NP when you order the harness.

I was also thinking of using this mid-shifter.

Forte's Parts Connection (508) 875-0016 - TREMEC DEALER, FACTORY FIVE COBRA PARTS, FORD RACING PARTS, FFR MKI and MKII, MUSTANG PARTS, TRANSMISSIONS, T-56, T-5, TKO, TR-3550

Has anybody used it?

thanks

Did you use electrical tape when you cut the wires?

I use a piece of heat shrink tubing.

hey your in lucky my 98 im doing a 5.3 t-56 swap to and i disconnected it from my stock 5 speed and it fits perfect in the t-56! so just be careful when you remove it.

did you do each individual wire? that shrink tube stuff is great!

Yep, one at a time. Took all of about 15 minutes.

good news, I thought it looked like the same fitting.

thanks for the info guys

I have a 5.3 T56 combo in a 92 fullsize.
I did not use the shifter relocator that you mentioned, but it looks fine.
I bought a kit from Keisler Auto that moves the shifter to the front hole, but requires some transmission dissasembly and reassembly.
The only issue you might have with the kit you linked is it may hit the transmission tunnel. Mine is very close with the stock crossmember.

I ended up removing much of the original wiring from my truck, but not until it was running, and all the bugs were worked out.

It is a fun swap.


Good luck

thanks for the info pnhigg

I got the 305 out and just waiting on parts!


a few more ?'s

I bought the professional products 85mm throttle body
-Do I use the egg shaped throttle linkage or the more rounded one like the one on the 305?

-What do you guys do about the "stop pin" on the tach, it looks like the needle wont be able to rev past 6,000rpm?

thanks, Kris

test to see if I could load a pic

this website is awsome!!!!!!

does that stick come up through your factory hole in the floor?

Here is a cad drawing I did with some measurements I took last night.

With the LS6 measurement I used the motor plates I bought off ebay that sits the block back 1 inch.

So I think I will buy the cheaper ones that will give me another inch foward.

I'm trying to do this so I dont have to cut up my floor.

After reading that about the clearance I will probably get the shifter that you have to take the t56 apart.

i was going to do the relocator kit but decided i wanted to run the shifter up through my console and i will be cutting another hole in my floor and using a hurst shifter i just got so i will have short throws with a small stick instead of the big goofy 3 foot long shifter that comes stock... but its all in what you want yours to look like ya know? plus it saved me 300$ for not having to buy the relocator.

I know alot of people do it that way, but I would think the shifter would be to far back and kind of akward for shifting fast.

I also want it to look as stock as possible.

to each his own

well if you took your stock 5 speed out and put it next to the t-56 its really not all that bad. as for quicker shifts its nice because with the hurst shifter its a short throw supposedly something like 33% shorter shifts. so ill post pics of mine when its done. might be a little bit though

I would recommend the B&M ripper shifter, if they make it for the LS1 T56.

I had one in a 95 formula and was really nice.

haha its funny that you mention it because theres a guy on here his name is QUIK hes got a crazy like 408 turbo or something nutty and he said he hated the ripper and told me to go with a hurst or a pro 5.0 so i did i got lucky and found one for 100$ on ebay brand new shipped. saved me 90$.

ttt to see if anybody knows these answers.
