SFI Rated Long Crank LQ4 LS Engine Flex Plate - ATI 915543

[@HillbillyThangs]

Just picked up a 85 Monte ss and a 04 LQ4 been trying to figure out what route I want to go... I think I’ve found it. I’m a complete noob to all this and trying to learn as much as possible. All your videos I’ve watched I’ve learned so much thank you for sharing!

I bought a 2002 Silverado 2500hd 6.0engine to put in my 02 suburban 1500 5.3 4x4 but the 5.3 had short crank the 6.0 has the long crank how do I make it work

[@Denarius18]

But can a 4l60e be bolted to a lq4

[@BAHRacingTeam]

I have a 2004 lq4 and using a powerglide. Which flexplate do I use with a 10.75” bolt pattern torque converter?

[@jasonbistarkey3992]

Will a standard 4l80e converter work or are the longcrank convertors different too? I have the stock 4l80e that came with the longcrank engine and need to order a stall. I ordered the flex plate you reviewed in this video. I know this is an older video, but if you could give me some insight that would be awesome. Nothing but conflicting info online...

[@WestcoastWrenchin]

What crank are you using? To make a long story short there is only one type of converter that you can use for a 4l80e they are all the same

[@HOONRV]

Hey man i need help on some fuel system questions

[@davy1458]

My lq4 came out of an 04 van with a 4l80....it has a spacer from the factory bolted to the crank flange....im putting it into a 71 chevelle....which 4l60 is the correct one for my engine?....the 4l80 in the van was bad which is why I'm not using it instead of a 4l60e....plus the 4l60 doesn't require me to have another new drive shaft made for my chevelle.

[@WestcoastWrenchin]

I would really push to get a 4l80e, its worth the upgrade I assure you. Remember that your 4l60e is essentially a 700r4. With regard to your situation you had a spacer bolted to the crank because the 4l80e is setup with the same spacing as a traditional sbc. The reason your engine had the spacer is because you have a common ls short crank shaft (not the oddball long crank 99 like mine). You want want a 60e which was bolted up to an ls engine. You'd want something 2002 and newer.

[@davy1458]

@@WestcoastWrenchin OK cool...thanks for the info....as for the 4l80 it's gonna have to wait...i just now purchased my stand alone harness for a 4l60e ....plus i just had a new drive shaft built two years ago for the th350 that I used run....the 4l60 and th350 are the same length so I still use my new drive shaft for now until I can afford to do the full 4l80 conversion....right now I'm just trying to get my ls swap finished and my chevelle back on the road....ive had it apart way longer than I wanted too....this. Is my first swap and Amway over budget as it is....plus I'm also repainting my car at the same time...once I get it all back together and finished then I will have the money and time to address a few corners I cut and replace or buy the things I couldn't afford at the time ....or that had to wait while I was saving up to purchase other things....im sure you been there yourself at some point...sometimeswe must make comprimises in one area to do things the right way in another area.

[@WestcoastWrenchin]

@@davy1458 i know the feeling and it is best in your situation for sure to just get it on the road! When they sit too long they sometimes done get finished! Cheers

[@alayijah]

Well this work for 4l60e?

[@wolf21storm21]

Will this work with a th350?

[@richardjimenez1246]

What converter would u use to mount up to 98 4l60e ? Do u need longer dowel pins ?

[@WestcoastWrenchin]

Id give ATI a shout, I'm sorry but I really don't know much about the 4l60e. It is a shallower bellhousing so I'd think you'd just run it without the spacer

[@jasonblume2707]

Great info, do you know if that flex plate will work when trying to do exactly the same 6.0 swap but with the 4l60e rather than the 80e?

[@alexanderperez2936]

Ima find out myself in a week or so. I just ordered one. Ill let you know

Did you guys figure out if it would work with the 4l60e?

[@mattb4164]

@@alexanderperez2936 did it work?

[@alexanderperez2936]

@@mattb4164 it kind of did. I also meeded a bellhousing spacer. But that could’ve been because of my converter

[@alexanderperez2936]

Would this Flexplate work with the long crank 6.0 and a 2003 4l65?

[@BadLuckGarage]

No, this flexplate is drilled for either a 10.75" or 11.50" torque converter bolt pattern so a standard 11.07" 4L60/65/70 bolt pattern will not work. The converter snout will also be too long. You will need a custom converter built to attach a 4L60/65/70e transmission to a long crank 6.0/4.8 engine.

[@jerryandalon2606]

Are you positive this will work with a long crank 4.8 and a 4l60e transmission??

[@cantyoufeelthelove]

What is the measurement from the rear cover to end of crank sealing surface?

[@WestcoastWrenchin]

Wish I could tell you but don't have access. What are you trying to accomplish? Long crank is same geo as an old school sbc

[@cantyoufeelthelove]

@@WestcoastWrenchin was just worried I have a long one, but I dont. I realized the old lip seals faced out so when it gets replaced it gives the illusion of a longer crank

[@WestcoastWrenchin]

Will this work for a 4.8 long crank and I’m trying to connect a 4l60e (automatic) trans. ??

Does it have the holes for a 3 bolt converter. I have the flat flex plate but I can't get a converter for it. Lq4 with a 4l80e. For something everyone does nobody knows Shit.

[@WestcoastWrenchin]

Yes I believe so, give ati a call tomorrow to confirm they've got great tech folks. I would highly recommend this plate as it has multiple patterns.

[@timh1187]

@@WestcoastWrenchin awesome thanks for quick reply. I'm on the verge of hitting the flex plate with a die grinder to make it fit. But I'd like to have an sfi cert and be safe.

@@timh1187 get an SFI, its not worth the risk!

It only lines with three holes on my 4L80e converter 🥺

@@nathanielmackinnon6738 I would review with the converter manufacturer, that is something which has to be perfectly centered and not dremeled. Are you sure its not a three bolt converter with two different bolt patterns?

@@BadLuckGarage in the exact same way you can install a 60e on an sbc you can install a 60e on a long crank engine. Long crank is identical to an sbc. Yes you will need the correct CONVERTER but that is always the case.

[@BadLuckGarage]

@@WestcoastWrenchin No sir I’m afraid you are mistaken unfortunately. The late model 4L60e stock converter flange needs to be machined if used with a flat flex plate. It’s a different converter than the early sbc 4L60 converter and will not seat properly into the crank.The early 4L60 converter was also a 10.75” bolt pattern whereas the later 4L60e is a 11.07”.

[@WestcoastWrenchin]

@@BadLuckGarage thanks for sharing

[@bloodybear333]

Do you know what flex plate you can use if using a th400 with the long crank LS?

[@WestcoastWrenchin]

Same one as this I believe! Th400 and 4l80e are both traditional spacing from bellhousing
