C3 CORVETTE 4 LINK FORD 9" SOLID AXLE INSTALL
At 700 HP with the LS7 in my C3, I don't want to have the rearend half shafts and or driveshaft to brake and come into the car and kill me, or lock up at speed and get out of control and crash and die.....so, for SAFETY REASONS.....I'm going with a Curry 9" rearend, AutoFab coil over 4 Link setup, and a carbon fiber driveshaft for safety and strength.
Curry Ford 9" with Detroit Locker, 35 spline axles, Wilwood disc brakes, QA1 dual adjustable shocks, 150 LB springs. Autofab Race cars coil over 4 link kit.

So ya got a 700 HP LS7? tech specs call for min 2" Primaries, 7300 RPM needs 28" long primaries, and a merge collector will help cylinder scavenging during the 35 degrees of camshaft overlap, and custom fit the D shaped LS7 exhaust port headers in a C3 corvette? They do not exist, so I made my own. then connect this all to a dual SS " exhaust system.....no problem....so I thought, On a scale of...

Did custom wire extensions for all the sensors, coil, distributor, FI so the ECM could be mounted in the car. Spent about an hour dialing in fuel map and timing settings for starting out. Test drive shows massive improvements as for as throttle response and HP!

Lake Shasta, Sacramento arm above Antlers
Which series carrier and ring pinion used ? Thanks.
I don't remember the carrier series but the gear is the 12 bolt THNIN series that the edges have been modified, to fit the clearanced 10 bolt case, the pinion is a 12 bolt but the shaft has been cut down so it sits deeper in the case, all custom modified ring and pinion that is no longer in production, If you go to the corvette forums there is a guy that bought a lot of Tom's innovatory and has a few items left, I did a 9" conversion for my C3 and said it would be cheaper to do the 9" here is my 9" install ruclips.net/video/G4TL6d1uB70/видео.html
Can u pm me please .John
Good Day. Can you provide some specifics regarding measurements, eg width of housing flange to flange , wheel offset ect, I have seen some installs without cutting into the fiberglass but I take it you wanted the car to sit lower ? Was that the reason ? Thank You
Good day, wheels are 6" back spacing, I wanted to sit as low as possible for better cornering, flange to flange was set to match the distance of the brackets that were welded to the frame, this will be different for every setup.
Soo many skills at work in this video. Including a lot of patience. Hats off to you. New subscriber her.🫡
Can you show how it’s made
Sure its about 11:30 into this vid ruclips.net/video/G4TL6d1uB70/видео.html
Just an update, LS7 head work and BTR stage 4 cam now at 700 HP and transmission is still doing great! firm solid shifts.....still!
ok, thanks for the input, just an update on the wheels and tires, made a slight change...........studio.ruclips.net/user/videoG4TL6d1uB70/edit
Sounds good
I like the look of
I have one . Its apart now. Not due to failure but upgrades. Hi comp pistons ... 1198 cams .... but I made sure to lighten that flywheel down to about 6 lbs ...... and will go heavy on the thread locker on that nut ....
For sure, it's here at 11:20 just a quick 140 MPH run ruclips.net/video/m8bJVeuVceI/видео.html
Good morning. Great video! Question. How is the Power-Lok doing with the new clutch orientation? Any issues? Thanks.
Good day, the diff is defiantly tighter, sometimes I can detect a slight bit of chatter during a slow turn, may need a little more posi additive, but all in all verry happy with the rebuild!
Sounds good. I just stacked mine yesterday the same way you did yours. Figured I'd ask while it's still on the bench. Have a good one.
@@mattritz5825 That is so COOL! did you find yours arranged like the way I found mine? It makes no sense for them to arrange the clutch discs that way?
@@BretMech Yes, mine was arranged exactly as yours was. I can't make it make sense either. Lol. So many wasted surfaces that way.
She's a runner for sure. At the end of the "Stainless Steel headers C3 Corvette LS7" vid. I watched the speedo climb QUICKLY! So yeah, that's a fast C3.
An automatic transmission is an intricated work of art. Someone needs to understand what they are doing when they service it.
Sounds Mean. I love the C3 I own a 76
What year Corvette?
1982, last year of the C3
Great looking car. Sounds great. And then the wheels. Nope gotta go
What are the Wheels? Cray?
Wheels are REV, all I could afford after the swap😆......what do you like?
Great car but those wheels stink I think something to the original look of these cars is best originality goes very far these days
Sounded badass and then the wheels….
I thought the same thing!! Haha
@@fernandomancini2296 ya ya, i know, I didn't like the look either after they arrived, I am doing a 4 link Ford 9" conversion and going with drag radials.......stay tuned, thanks for the input!
@@BretMechsounds awesome is that a direct injection motor ? And yah scrap the wheels ! 😎
@@markgiraldes4062 No DI , just a modified LS7 crate motor, BTR Stg 4 V2 Cam, CNC ported heads, Ti and Inconel valves, 12-1 Comp. custom SS tuned EL headers. BTRs Dyno with this setup shown 700 HP naturally aspirated.
@@BretMech Sounds done and done right ! Thanks keep at it ! 👍😎😁
Another LS7 bites the dust. I am sorry this happened to you too. '04 C5 LS1 Corvette driver here. I got real close to getting a C6 Z06 but someone beat me to it and I ended up getting a nice clean cheaper base C5. It's been an okay daily driver with a recent BTR stage 1 cam (.613", .605" lift), dual valve springs, titanium retainers, etc. ATI super damper, Kooks headers, other mods, HP Tuners tune. 412hp. It is nothing like a C6 Z06 but I hope that I don't run into this really well documented point of failure with the world famous LS7. Gosh I wish they would of recalled that motor and fixed that fatal flaw with the valve guides. What a shame about what I think is the greatest LS powerplant GM ever produced.
Sounds bad ass
Same mufflers as Joe's but 4X as loud for some reason???? and that with the cut outs closed!😬
Use an air hammer on the end of the pinion
Awesome stuff dude...I just happened to see this video. The funny part is that the next day, I get to rebuild a dana 80 off a 2000 f350xl 7.3 ..so thanks for the insite...I can't wait to crush 450 pounds of torque..lol
Thanks, ya, the more I think about that pinion bearing I should have cleaned all that rust off the pinion first with wire wheel, sandpaper, brake clean, and compressed air before trying to remove. I can't imagine trying to do this on the vehicle......
Hey there. '04 C5 Vette driver here. So, is that a factory GM timing chain or an aftermarket piece? If it's aftermarket, please divulge from whom it came so others can avoid that mess. I wondered the same thing about my new cam and header install by a local shop last year. The owner told me they installed a new timing chain and LS7 chain guide, but re-used the gears because they looked okay. There is a lot of crummy aftermarket parts for the LS that worry me. Which is why I went with Michigan Motorsports on the BTR stage 1 cam kit with titanium retainers, Johnson lifters, plus other parts. Kooks headers, catted x pipe and mid pipe from another site. I was trying to avoid issues by not "cheaping out", but even that's no guarantee.
Hi there, the timing set in this vid is of a brand new 1800 mile LS7 crate motor with the factory single chain, I replace it with a comp true double roller can be seen here ruclips.net/video/xm1fXv2Bvd4/видео.html
@@BretMech Oh, it was a factory set up. Well just darn. I read you say it was a crate motor but I thought it might have been an aftermarket timing kit.
The results are in, this is after adjusting Tq Managment and injector end angle custom map on the Terminator X ruclips.net/user/shortsQ8cEY4zBlqo
“I ain’t gonna lie that was scary” at 10:08. Just awesome!!!😂
Awesome video! Where are you located? Do you do work for others? I’m interested in having you rebuild a Dana 80. Thanks.
Thanks for the tip from Green shorts performance on the knock during startup. turn off fuel prime. it works!
O ya! iv seen your Vette vid, that thing is wicked!
That will be a spicy cam. What trans and rear gear are you running? I can't wait to hear it run. Do a lot of people run the double roller vs an upgraded single? I have a '73 C3, 427 SBC 242/248 @ .050, .585. Dart block, AFR 220, Holley EFI, 1206 miniram, TKO. Side pipes. minilite style wheels. I'm collecting parts for a LS7 build for a 66 Nova drag N drive car. I bought a smaller Cam Motion camshaft. Duration at .050 - 228/244 Lift with 1.8 - .648/.639, Lobe separation 115, Intake center line 112 (pretty close to the cam in the 570 hp LS7 crate engine I think). I went with a t56 magnum 2.66 first. .63 sixth. Moser 9", 3.73, spool. Split mono leafs with caltracks, sliders. Smith Racecraft front end should ship in June. I have the MSD intake, I have the Z28 factory exhaust manifolds that I want to try first. I'm trying to keep the car looking stock on the outside.
Hey, that sounds like a fast ride! Iv got 373s and a Chance converter 3000 stall Infront of a 4L65E that I built, its on my channel, spent 6K in parts alone to include the Sonax 6 pinion gear change planet, should handle 1000 to 1200 HP, and super lightweight.
Sounds good, nothing like an LS7 corvette
This is the NEW BTR LS7 Stage 4 V2 .662 lift on both the I and E more duration on the Exhaust, 267 deg @ .050! 111 LSA. this cam is so top secret that on the cam card it says Pat Pending!
That sucks about your chain slack at such low milage. I thought this would be a good time to talk to you about your cars extended warranty.
That is funny.....are you trying to sell me an extended car warranty? Ha HA, Na, this is a GM crate motor, LS7 570 HP, they do warranty it for a year but it is a waste of time to argue with those guys, too many stipulations, for one, they will only warranty it if it was installed by an authorized gm dealer, no way they are going to put this in my 82 C3 Corvette, got a Comp Cams dual true roller going in...to turn a stage 4 cam.....
Measure guide wear at top of valve and see if it’s the same
OK, so you do know that valve stem to guide clearance spec is .001" to .0024" right? and in the vid I was measuring .100+ movement, no way in hell does it matter where you measure that valve with .100 movement, the valve guide is gone and so is the engine when the valve head broke off and destroyed the engine.....but yes I know what you are saying if it is around .010" use the fucked up GM wiggle test guidelines that they pulled out of their ass to cover up their major mass coverup that has cost the consumer 100s of thousands of dollars in damages that they do not take responsibility for.....sorry for the rant, I just spent 6500.00 to have my heads redone, that's with me pulling the heads.....
For that price you could of got good set of after market heads. 😮
Pair*
@@sick7camaro482 price yes, but not the quality of the port, mill and valve job, the special guides that are used in Indy cars, BTR .685 springs With Ti retainers, and the special Ti moly valves, and Inconel. it all ads up. AHP are well known in the Corvette community for the quality and reliability.
The autometer dials are so much better looking that the dakota digital ones...too back they are such a pita to install...
Forgot to mention we had them mill the heads .030 and going with a .040 head gasket instead of the factory .050, so .040 total. we live at 5,000 Ele and the static compression was at 170 GPSI need to get back to 200-210ish, stay tuned for the test drive and thoughts.
Static cranking compression now measures 208 PSI at 5000 elevation with the GM 570 HP crate motor camshaft

Can I ask what size aluminum plate you are using? Guessing maybe 1/8".? Also, where did you get the plate? I'm having trouble locating aluminum at a decent price. :)
I used aircraft aluminum T 2024, from Aircraft spruce, .063 This is heat treated and it is what I used to skin the wings of my Vans RV 7 aircraft I built.
@@BretMech Thanks for the info! One last question. What did you use to cut the large holes for the speedo/tach gauges?
@@kevinb21 I dilled a 1/2" hole inside, and then used a metal blade on a jig saw, no problem with aluminum.
New subscriber
If that pinion seal is the same part# as a 12 bolt, the Ratech is the ONLY seal that will work without putting something under the seal lip. It's part #RAT-6109 from Summit. I have the same issue when i build 12 bolts and i found this seal. Nice diff, it's a shame you can't get those gears anymore.
Good info, Thanks!
I appreciate this video man, thank ya
Nice, do you have the measurements of the plates? I need to do the same for an 80 corvette but I bought Glow shift gauges. Greetings
Sorry, no measurements, I just eye balled it and centered each to where it looked right, you can cut out paper patterns and see what looks right. no rules to follow when you are doing your own thing.
Hello, can I istalled the 1976 C3 Corvette cluster into a 1980 C3, like a swap , just the cluster and front face????
Hi, I'm not sure with the dimensions of the earlier C3s, as you can see in the vid, I cut the entire rear half of the cluster off to make room for the new set.
Great video and clean looking 'Vette, Good job!
i have a stock 73. i moved the e brake bracket . do you think i can fit 275 6o 15 in the rear? ive heard many people say it should fit
I have not tried a 275 with stock trailing arms, the offset arms no problem. there are a lot of combinations to include wheel back spacing to clear the arm but then you must pay attention to the tire clearing the fender.
shorter springs and modified sway bars are commercially available to fix the clearance problems
Wow, nice job guys. Very very professional. I’m envious of your knowledge😎
This is the destroyed transfer case: ruclips.net/user/shortsg9QInZ2tJA0
congrats great attitude thru out the ordeal, i wish i was there to relieve your pain, i’m no mechanic but metal never wins over my focus, 3$ of cut off blades and a 6” 120 volt angle grinder those blocks would have zippedoddin 30 minutes congrats thou excellent job thanks
