So i figured it was about time to create the build thread for this. The rundown is I bought an '82 back in December with 23k original miles. It had a GM V6 put in back in the 80's and then had sat in climate controlled storage since '92. The body and interior are almost mint. It came with beefed up rear suspension with a corvette zr1 rear end with 3.45 gears and a big 4 core aluminum radiator. Here is how it looked when i picked it up.







The engine bay is pretty normally. The previous V6 had the motor mounts/stands made to fit on the stock cross member. I just bought some s10 V6 mounts to slide into the stands and then universal v8 to ls motor plates and it bolted right up.







I will be dropping in an LQ4 truck motor that has upgraded valve springs, head studs, cam, oil pump, timing chain, pushrods, rockers and rod bolts. Still working on what intake I will be running. have a few options but size is a limiting factor. i have already bought an S480 T6 race cover with 1.32 AR. It is a pretty big turbo but once clocked right should fit behind the headlight. The transmission is a 4l80e that will need some massaging of the tunnel to get it to fit but will just have a converter, cooler and shift kit. These have held all day with 7-800hp with just that. Fuel system has been put on hold because I am waiting on some responses from people regarding a quiter fuel pump, but not a big hold up. To run everything will be a Holley Dominator ECU that has boost control, traction control, meth control, can control the trnasmission and hopefully will have the RacePak dash configured soon to go in as well.

Below is as of last night I dropped it in and installed the accessory brackets to see which side the turbo should go to get the 5" downpipe to fit and if the holley hi-ram I bought would fit, doubtful without a bigger baking pan on that hood and even though not sure if a 4" charge pipe would make it with the radiator. Space is obviously tight.

That intake is ridiculous, why not go with a FAST manifold? I don't think Pro Stock hood scoops look that great on these cars.

Can't say I am a fan of a domestic motor swap, but the car is in amazing shape!
Great looking interior and paint, good luck with the project.

The price of a fast new with fuel rails is about $400+ then this one. Plus the longer runner length increases the power band. Also going to a car intake would require all new accesories that I was trying to stay away of. I did not know that this intake was as big as it is. I had read it was large but assumed since I got the truck intake to fit with the current baking pan scoop. I do not want a cowl or anything bigger on the hood. The only possible change would be one that centers it out. Im not opposed to the look of it at all as it doesn't take away from the overall car.

LS6 style intake would fit a lot better and probably make more power. What oil pan are you going with? Glad to see another person joining the LS camp.

Cool, did the hood already have the scoop or did you already do that? it's hard to tell by the pics but it looks like it as some type of provisions already for the taller engine/intake?
It was already on it. not the cleanest as it is off centered towards the passenger side.

Yes they are great intakes, might end up with one all depending upon water pump if I can fit that kind. Still debating that or just a vic jr singe plane with an elbow that will clear the hood as it is. And the oil pan I am using is the holley ls oil pan for swaps. dead even with the bottom of the crossmember.

Cool project and interesting history on car. Do you know anything as far as who did it or the shop? Do you have pics of the rear diff and suspension?

Ditto, would love to see what was done to the rear end.

Are you keeping this thing as a street car? Hopefully that low miles body and interior will be preserved, so few left in this condition and milage!

The paperwork i have says that it was Katech I believe. The guy had said he spent around $40k back in the 80's for everything. It was a supercharged V6 but they never could get it set up right so they took the supercharger off and it was NA. i don't have any pics on me but can get some this week for sure next time I work on it.

Yes this will be a street car with AC and heat(fingers crossed) and will remain pristine. I searched for a while after selling my Trans Am trying to find the right vehicle to get into that was clean, not chopped up and would make a perfect candidate for this swap.

No real update as I have been terribly busy with work since we just ended our fiscal year. Luckily I will not have to travel for the next 4-6 weeks so I will have more time to get this finished.

This weekend I placed orders for the last of almost everything minus transmission items and some miscellaneous. Hopefully everything will come in the end of this week. I am just waiting on the below"

Fuel Setup (Magnafuel 4303, -10 feed/return, sump kit, pre/post filters, regulator, fuel rails, the good stuff)
Turbo drain/feed lines
Precision 66mm Race wastegate
JGS 60mm BOV
eBay interooler 31"x12"x4" (has done 1000hp on other lsx motors)
LS6 intake manifold
3/8" Pushrods
Holley dominator ECU (I received the wiring harnesses and everything just need the actual ECU)

Still trying to figure out wheels. I know the Weld Draglites fit, not a huge fan of the looks. I want to stay at a 15". Possibly looking at something custom made. i sent some emails to a couple vendors, waiting on responses. Rear tire will be a Nitto 555R 275/60R15. if that doesnt work I will step it down to a 50.

Now the transmission I want to run is a 4l80, basically turbo 400 with overdrive. It is super heavy, bulky and I am contemplating not running it. Where the motor sits I will have to BFH mod the tunnel for the droop from the bellhousing to clear the converter. I will be spacing the front end down .5" to 1" this week to see if it will give me the clearance I need, but I am afraid that this will cause the tranny oil pan to hang too low. If this is the case then I will go with a built powerglide and call it a day.

Still looking to be completed in April sometime...

So no real update. ECU is still back orderered along with the injectors, both Holley. Have not received my fuel system. The tank has been removed along with all fuel components previously installed. I can say it was a complete bitch to remove those hardlines and pump with the rear end in place. Have ran degrease in the tank to remove all fuel residue for when welding in the sump. I have not done much else with it. Miscellaneous parts have came in. A great deal came up locally on a powerglide that pushed me to get the transmission fitted to see if it would work with out cutting up the floor pan/tranny tunnel. Well in the first pic the center bolt need to come up to the cross line.



Measured and it needs to go up about 5 more inches. I can't really lower my engine mounts any because the oil pan will hit the cross member. I had talked about spacing the front end down about .5", not sure if I will or not. On both sides of the tunnel there are these drop downs that the previous tranny mount was. These will definietely interfer if I don't remove them with this transmission.






Now I want this transmission because it will hold 800 with just a shift kit and a converter plus it has overdrive so that .75 last gear will drop the rpm's down a lot for cruising on the highway. But if it won't fit then I will simply go to a powerglide. Locally one is for sale that has all the bells, whistles plus an awesome converter for about the same price I will be into this stock one with shift kit and converter. The size difference between them are astonishing along with it be less than half the weight of the other. such a tough decision on what to do...

This is the best I could do with size comparison.

My laptop crashed or I would post some more pictures. Ended up going with a glide. Picked it up yesterday and it bolted right up without any modification to the transmission crossmember that was already there. So this makes this ls swap truly bolt in since I have not made a single custom mount, just some clearancing. I tank the gas tank on Friday and to talk to the guy about building the turbo kit. Hopefully will drop that off this next week. Fuel system should have shipped yesterday. Appearetly they shipped red/blue fittings instead of black. My injectors shipped today. I just need to order some wire for extended the fuse block to next to the brake booster and we are good. Here are some teasers.









Last but not least. Top is with the v6 and bottom is v8. Definitely will be going with coilovers but not bad.

that intake manifold fits much better than the old one. the word tight is going to be used often in this build thread.
looks good keep it up!
