Does anyone know if you can redrill the bellhousing bolt pattern on the Tremec 3550/TKO trans, like the fords 3550, to GM's Muncie bolt pattern?

Thanks.

Ford / 4th Gen T5 to LS adapter: http://www.hotrodworks.com/product/f...ssion-adapter/

Sorry for the slow movement... A Jeep slowed progress on the Volvo swap where this junk is going.

Which honestly is not a good option. The Ford and Chevy T5's aren't rated for much more than ~300 lb ft of torque... that won't last long behind an LS.

Yeah the T5 was a child of the 80's, when engines had a hard time pulling the fuzz off a dandelion...

I have a used POS Non-WC T5 behind a 5.3 w LS2 cam for years. No problems. But, I do not leave hard in 1st.

Everyone talks trash about the T5, but IDK anyone personally that has broken one aside from regular use/abuse. From kill stories, it seems that 3rd is the weak link.

With the new T56 sychro rebuild kits for the T5 I bet the TQ/HP limit will be raised.

A fellow local gearhead has a TKO500 behind a Caddy 500 Turbo (1000+ TQ) in a Gen III Camaro - daily - and it lives! Not apples to apples, but dont sleep on a T5 base.

Shoot a WC T5 driving a low gear small tire car could live forever... Maybe.

Upgrade the WC T5 to an Astro or G-Force gearset, they're rated over 500 ft-lbs...

You can go through a few T5s, at the right price, before even getting close to a used T56 or Tremec, that's my plan for now.

Michaler Yount uses a T5 behind a LS3 in his Volvo. I think as long as the T5 is not abused and there are some traction problems, a T5 will be fine. The great thing about T5s is that they are light, relatively small, shift great, and are well supported in the aftermarket.

Hello Everyone,

The formula is set i see for using the ls motors with the shorter crank. What about if i already have an engine with the longer crank?

I got tunnel vision while shopping for a LQ motor. Finally finding a LQ4 for $500. When i arrived at the location noticed the truck was a '99.
Pulled it myself and got it home, tore it down noticed the crank seemed to be longer. Which started my search finding out about earlier 6.0s and then this forum and post.

What i have is a 69 camaro with a TKO600 and a quicktime bellhousing. Ditched the SBC for an LS build and now im sweating the details of the conversion.
I tried searching online but didnt find conclusive info if there ever was a silverado 2500 with a 6.0 and a manual trans.
Read through all these posts on this thread and i dont think unless i missed it where anyone had the long crank.

Additional searching online found this site which has some useful info, but for the short crank guys.
https://www.novak-adapt.com/catalog/...en-3-flywheel/
And with some additional details on crank spacing. https://www.novak-adapt.com/knowledge/gm-crank-spacing/

So looking like my options are?
1. Replace the crank?
2. Machine the crank?
3. machine the ls bolt pattern in a BBC flywheel since the crank is in the old style length?
4. Purchase an LS00-28 from the novak adapt place. ( I'm just trying to save money like everyone else here.)

Anyone ran into this yet?

Michael,

I don't believe that the 2500 with a 6.0L ever came with a manual transmission.

I know you may not want to hear this, but if you got the engine for only $500, why not sell it? Sure seems better than buying a bunch of expensive parts to cobble together a questionable solution.

From earlier in this thread...

I don't mind the cost if i get a good result. I will need plenty of clutch engagement (+/- 550 hp)so the sachs clutch might not be able to work for me anyway.

No can do on the sale the engine for 500. Block already refreshed, bored .030 over fitted with some +4 cc forged pistons, Heads Texas speed PRC cnc machined. too late to stop now. i can always buy another crank.
Just was hoping to use it because of the old school geometry with the crank being in the proper place for the bellhousing and trans i already own.

Dosent look like any of these earlier mentioned solutions will work for me, I am 26 spline and my crank is already .400 longer due to being an early 6.0 that was teamed with the 4l80.

If your block is ready to go, just get a new later model crank. You can even choose a OEM forged crank, like the LSA crank. Just my opinion....

I agree. My experience was in the fox body world, but it's relevant. Back then people were blowing T5's up all of the time. I managed to put 140,000 miles on my modified 91 with out a single problem. Clutch started slipping well past the 100,000 mile mark. Was I easy on the car? Sure, often. The rest of the time? Hell no. A young guy in a loud, fast Mustang? Do the math. But I'm not an idiot and it survived with well more than 300lbs of torque for many years. I'm sure it was blown up promptly after selling the car, but it did just fine for me.

BTW, the car never had anything but high perf street tires on it. And 3.55's which lov-lov-loved.

Now were talking. I like where you are going with it.

Alternatively, I think those early truck cranks have the same pattern as the car/late crank, but the offset of an old SBC - so you could get an LS1/2/3/7 flywheel and clutch combo (which has the correct spline pattern for the TKO), and it should in theory have close to the right stack height for the original throwout arm/bearing. It's worth doing some measurements, but for running an old transmission on a budget, that almost seems like the ideal crank to have.

Also, if you're going hydraulic clutch, the shims or lack thereof (at least the Quarter Master slave that I used... IIRC because GatTagO used it?) behind the slave cylinder can take up the slack in either direction.

The novak site has a listing for a manual trans 4.8 flywheel for long crank.
Might be worth checking into for a long crank 6.0.
