G Body Lsx Swap Mounts my opinion Holley is best

I tried almost all the mount solutions on the market: brp, custom, setback plates, etc. The Holley system that is built-in for truck intake, accessories, and the 4L80E is the way to go.

[@erikryan9204]

Looks good man! Doing a swap on my Grand national, I’ll be using Holley setup now. Thanks for the info

[@jamesmacklin9735]

Thanks for all the info, much appreciated! i'm doing an LS twin turbo in my 84 GN , great info!

[@raymanjohan8838]

This helped me a ton...I over think soooo much. I need info like this thank you.

[@quentintraywick1524]

Glad i found this..im about order all holley stuff for my 6.0 4l80 into my 86 grand national..

[@PENNYLS1]

Looking good. I went with the same setup.

[@johnnyfive3872]

Interesting take on the crossmember. I actually had both a Holley and the Gen 2 G Force crossmember in my hands. I actually did a video comparison that I have yet to post. But in my opinion the G-Force is way better design hands down. with much better fitment. I didn't like the cheesy design of the Holley plus the bolts didn't line up properly.

[@allendiaz662]

Did the passenger side coil bracket hit your ac box? Mine does, even if i shave it down. Too close for comfort.

[@jacksmith3189]

Good information Thanks

[@TargaWheels]

Thanks for the info!!

[@flyte9524]

thanks for the help

[@shawng7902]

i just got the 302-3. new super low profile pan. clears a 4" stroke crank that the -2 doesn't. and it comes with 2 half-inch pipe thread turbo oil drains already tapped into the pan just forward of where your return is ran. slick piece for sure just takes a little windage tray trimming

[@ChipAndBytes]

That was not available back when I did mine but I would get it now

[@coltengottschalk1049]

Transdapt worked just the same keeps the engine off the firewall as well

[@acollins9277]

Thanks for the info.

[@TJhippie420]

Thank you ! I have been trying to find info on the easiest solution and all I got back was how people jerry rigged or fabbed something.

[@jermaineknowles87]

Nicely done

[@FlipCity703]

Thank you thank you

[@drejackson1000]

So power steering pulley was clearing?

[@henrysordia9844]

Great video Chip, very helpfull. I also have a 87 Grand National that i am about to remove the 3.8 out of and go Turbo charged LS.

[@nicholasmcelhose9195]

Should keep the Grand National with the 3.8 if it a true GN plently of other gbody to ls swap

[@ChipAndBytes]

Thats a great plan Henry.

[@acollins9277]

Great info.

[@shandyellis-brown8091]

which intake clears the hood??

[@playamadenawf817]

Did you relocate the frame mounts?

[@williampalmer8418]

Part number on the mounts , Oil pan and your set up for the trans cooler including the AN fittings please and thank you

[@ChipAndBytes]

Google "holley g body LS swap system"

[@HeadFlowInc]

Oops, Holley pan is a bit pricy, was looking at the CTS-V pan

[@ChipAndBytes]

Only Holley 302-2 will fit with their mounts. f body, ctsv, and hummer won't fit unless you cut them

[@HeadFlowInc]

Chip Currey I'm using the Transdapt frame mount, Energy Suspension engine mount, and LSX Innovation block adapters with 4 positions. My frame has been modified by the previous owner so hopefully no issues. I think the CTS-V pan may hang slightly below the crossmember but doubling the cost to the Holley pan is hard to justify. I see what your saying about your setup and mounts. JD

[@Daytonatheman]

need info on frame extension bracket 200r was what i was running now need the 1 u have

[@ChipAndBytes]

It comes with the holley swap cross member

[@mikeskidmore6754]

I think Holley makes 302-1 and 302-2 oil pans the -2 is the second design and has better clearance for the crossmember on a Second Generation F Body like a have plans for ..

[@mikeskidmore6754]

It looks like the Trans Crossmember has nice cut outs for dual exhausts ..

[@andymorsette704]

I tried using the cts-v pan on my gbody with factory a/c. To tight to install. Assuming you are showing 302-2 pan? Do you have factory a/c?

[@ChipAndBytes]

302-2. Factory a/c box is still in the car.

[@joseb1700]

I’m doing the same exact setup but I have a regal limited v6 . What bushing u using on ur trans cross member.?? N is that trans cooler good for the 4l80 ? I heard the trans doesn’t like them.. can’t I just use the original rad setup? Also can I use the original hard fuel lines cause I’ve noticed every one goes with new lines.???

[@ChipAndBytes]

Using a factory transmission mount for a TH400 in a 70 Chevelle - can get them at any parts store. I have never had a problem with the cooler or transmission. You can try the radiator setup if you want.

[@av8bud]

Hi Chip, just tried putting this pan (302-2) on the 5.3 i am rebuilding to go in my 83 El Camino. Wanted to make everyone aware, it wouldn't fit on my engine. the front part of the pan makes contact with the piston rod cap bolt, just barely but enough so that i couldn't hand crank the engine. I tried trimming the windage tray but no luck. Since it may be risky to shave down that bolt, i'm going to try swapping it with the 302-1 and see if that works. Hopefully it will have enough clearance around the frame when i put it in the car. A thicker pan gasket may be all that's needed but just wanted everyone to know that it may not fit your engine.

[@CountyGarage207]

did you ever figure this out? I have read of guys cutting off that part of the windage tray completely

[@markadame8501]

Any update ???

[@ChipAndBytes]

I have not had any trouble installing this pan so I am not sure what is going on in your case

[@brianfructuoso9681]

Hey Chip what trans cooler line are you using ? Like to know the part # and what radiator you using as well??

[@ChipAndBytes]

If I did this again now I would just use a normal front trans cooler. Using auto zone radiator for a 305 g body el camino with the tow package.

[@evilmanhut]

Can I get some part numbers I'm doing this exact same swap

[@ChipAndBytes]

Google "holley G body ls swap system" they have it all organized

[@flyte9524]

I purchase atp flexplate for the 4l80e

[@ChipAndBytes]

I am using the stock 6.0 flexplate

[@manuelperez-fh6jc]

hi chip by chance I have the 302-1 would it work with the holly mounts on my gbody ?

[@ChipAndBytes]

Probably will

[@imacarguy33]

what brackets and mounts do you recommend for 68 pontiac lemans. ??? thanks

[@ChipAndBytes]

Pontiacs are really hard because the shape of the BOP transmission bellhousing is much different. my dad had a 67 gto. we used Holley's mounts and pan but had to raise transmission tunnel for the 4L60E. I don't know how much different a 68 is, but be prepared for it to be more difficult than a Chevelle - all the mounts are test fitted on Chevy's since they are the most common.

[@anthonymack2415]

does these allow the truck intake manifold under stock gbody hood?

[@ChipAndBytes]

yes

[@imback8596]

Chip Currey I am having trouble with this cross member no details instructions nowhere on the web

[@jeremystone9783]

4l80 fitting with no tunnel modifications on a gbody! You just discovered the wheel my friend! What's the model numbers on the engine mounts and trans crossmember? I always thought I'd have to run the 4l60 because of mandatory trans tunnel mods... I have an 87 cutlass 442... How's the power on that 6.0? I have a 2014 L96 6.0 with vvt in mind.. Coming out of a wrecked 14 GMC Sierra 2500hd 28k miles $3k ecu, harness, and drive by wire pedal included... What you think?

[@ChipAndBytes]

hello...all the parts can be found on this page www.holley.com/products/ls_power/ls_swap_systems/1978-88_gm_g-body_ls_swap_components/ please don't install a 4l60e....I can say from time and experience that they are terrible. the 4l80e fits with so much room you can easily put in all the bell housing bolts with no special extensions or anything. i was running my 6.0 with a t76 single turbo. it would burn the tires on the freeway but the original oil pump in my engine went out and then I wiped the cam bearings. trying to get it back together now...block is fine.

[@jeremystone9783]

Oh ok so the swap plates are what enables the 4l80e to fit.. I bought some set back plates off ebay $30 bucks.. Whats your email I'll send you a pic of them.. Havent did anything yet.. I think they're from Lsx Innovations

[@ChipAndBytes]

I'm familiar with those and tried them....they do not let the 4l80 fit. It's the combination of the Holley mounts and cross member, and the extremely low clearance Holley pan that lets everything work. The Holley mounts and pan set the engine about 1" lower than setback plates plus an f body pan....that 1" is what let's the 4l80e fit.

[@king9968]

do you have to use the holley mounts to use the holley pan

[@ChipAndBytes]

king9968 I really can't answer that. the pan is one of the lowest profile available

[@flyte9524]

my flexplate does not have the spacing like your 4l80e does what did you do

[@ChipAndBytes]

The factory 6.0 flex plate is spaced differently...it's made for the 4L80E or TH400. If you are trying to use a 4.8/5.3/5.7 then you need to either get a 6.0 flex plate or have your converter made for the smaller 3 bolt flexplate

[@guywiththebaja5690]

Do you have to use Holley headers with that kit or will other ones work

[@ChipAndBytes]

The holley/hooker bolt on turbo LS manifolds are the best out there

[@girlsallfall]

What’s up chip ! Need a little help . I installed the mounts, then I tried to install factory a/c an bracket would not fit .... NEED HELP . Should I go after market what’s the play here ? Thank you

[@ChipAndBytes]

You have to cut and box in the frame to run the low a/c. Otherwise holley makes a great top mount A/C for sanden compressors.

[@kevmoney265]

Do you need a special trans mount for that crossmember?

[@ChipAndBytes]

70 Chevelle Th400 mount

[@Chasemanuti]

What mounts did you use on the gto and oil pan?

[@ChipAndBytes]

Chasemanuti it also uses the Holley 302 pan with the hooker LS swap mounts for a 67 chevelle

[@AlazarAnbesaw]

The video quality initially sucks but the explanation makes up for it. Thanks for the info!

[@jeremycollins5034]

did the coil pack clear heater box?

[@ChipAndBytes]

I have another video on that. if your car just has heat the box is smaller. mine has ac. I cut the part of the bracket off for the last coil then mounted that coil over one of the farther forward ones. it definitely won't clear. that is the only clearance issie

[@jamessanchez5567]

What transmission lines and fittings are you using?

[@ChipAndBytes]

-8 AN I made.

[@jonelee36]

Hey chip I need your help friend wat clamshell do I use and we're do I mount them on the frame or do I use stock clamshell please help me thanks

[@jonelee36]

I got the same motor mount you got and oil pan I basically went with your ideas on ls gbody swap can you pleas help me

[@ChipAndBytes]

@@jonelee36 Get the clamshells from an 85 regal that originally came with the 5.0 305. You can get them on rockauto. They mount to the g body frame with no drilling. You will have to drill through the original V6 frame side mounts to get them off.

[@brianfructuoso9681]

What about your shift linkage??

[@ChipAndBytes]

Using junkyard 4th gen F body Camaro/Firebody factory shifter that was originally for a 4L60E. The 4L60E and 4L80E have the same shift detents. The 200-4r and 700-r4 have different detents.

[@vb5457]

What is that would pan part#???

[@ChipAndBytes]

Holley 302-2 pan

[@chadgardee1496]

What engine you have what generation

[@ChipAndBytes]

Gen III 6.0 LQ4 with Gen IV internals

[@geralda9119]

My regal a 87 I have those hooker plates what exact clamshell r u using

[@ChipAndBytes]

85 regal original 305 5.0 frame side clamshell

[@johnnyhammonds2475]

How much for the complete set up

[@ChipAndBytes]

depends on how much you pay for the engine and transmission...mounts are not that much Google "Holley g body ls swap mounts"

[@geralda9119]

my 6.0 came from a 05 escalade goin in a 87 regal school me wat trans should I use do the can I use the same fly wheel ,oil pan, flywheel wat intake an carb should i use an rear end

[@RiskIt007]

is that your real voice?

[@ChipAndBytes]

Yes

[@1017cutlass]

Is that stock location motor mounts or their offset forward or back mounts? I'm in the beginning stages of a 5.3 swap into my 87 442 and want to run a 200-4R because I have a lighting rods out of a 83 hurst would stock location mounts work?

[@ChipAndBytes]

1017cutlass they are the only mounts Holley sells as far as I know. they can only be installed one way

[@36nick4truth]

1017cutlass I remember everyone hating those transmissions back in thre day saying they couldn't handle any torque. People only trusted em behind v6's. a metric 200 they called it. I think you'd have more fun Makin those lightning rods work on a 4l60 or a 700r4 Sell that 200 to somebody do in a stock resto. Peace good luck!

[@justplanefred]

36Nick4Truth the Metric 200 looked like a slightly smaller Turbo 350 but instead of 13 pan bolts it only had 11 and they were 3 speed plus they were junk. If memory serves me correctly GM only made them for 2 years. The 200 R4 was different, I think they were still fragile but not nearly as bad as the Metric 200. They had a very unique pan. The 700r4 and 4L60E would probably been easier to fit but are only good for about 450 - 500 Whp
