I used Schoenfeld headers with 1-3/4 primaries and 3" collectors. I had them ceramic coated. The rest of the exhaust was done with stainless mandrel bent tubing. with an X pipe and stainless race mufflers. I used band clamps on everything including the header connection. The big problem I ran into was finding square port headers with large tubes for angle plug heads in a Corvette. The only modification to the headers was the collector had to be turned down 15° to clear the floor. They tuck up close to the underside and have nice clearance for the Milodon road race pan. I converted my car to a 4L80E transmission so my rear crossmember has clearance for dual exhaust.
That sound like a pretty cool system with the 3.0 inch pipes out you should be able to flow some pretty good Hp. I’m sure it sounds good thundering down the road. My car on its best day might be 300HP so the 2.5 inch pipe is more then enough.
@33milegarage34 it's barely enough. I have a Dart SHP 427 making 550hp. Ideally I need 1-7/8 primaries and 3-1/2 exhaust. Since it's mainly streegowhat i have Ideally good enough. It's been a real pain trying to tune the FAST XFI multiport efi system. I need to take my car to a professional tuner.
I appreciate your video. I too have a 1970 Corvette. I scored a pair of Hooker Super Competition headers 2134 for $200. The A/C is making the passenger side a bear and I haven’t gotten to the driver side. At least I know about the oil dipstick.
Thanks, that was a fun video to make. Hooker super comps cost over $1,000 new. Wow…nice score! Curious, what exhaust system are you planning to go with?
@@33milegarage34 it was to good of a deal to pass up even with a three hour round trip. I have the original exhaust tips like what you were showing and they look brand new. My original plan was to go full 70’s look with Cragar’s and side pipes, but I’ve decided to forgo burning my legs. My current plan is to basically do the same exhaust as you have done. I don’t have any welding skills/experience so I wish I could find a bolt on system. I was planning to go with Black widow “neighbor hater” mufflers but yours really sounds good. I haven’t figured out how to mount the alternator with headers. What bracket did you use? The one on there connect to the driver side exhaust manifold.
Great videos these are very helpful and very informative I just came across this site so I'm back tracking to watch them all. Took me a while but I just realized ....HEY I KNOW THAT DUDE keep up the good work, keep um coming Scott W.
We installed these headers on my 1972 Vette. Perfect fit and the exhaust clears with room to spare even with the lower Ridetech suspension. Thanks for the recommendation. Love your videos, keep up the good work. You have to have a sense of humor to work on a C3 Vette.
Thanks for the comment and glad the video help you out. How do you like the Ridetech set up? Your not kidding about the sense of humor.Thanks for watching!!!
The Ridetech system is definitely worth it. It is a two man job and the installation video is misleading about how easy the install is. Taking all the rusted bolts out was one problem for sure. If you do this, install the Borgeson power steering system. It is relatively compact and greatly improves your steering. Unlike rack and pinion systems that are available it doesn’t impact turning radius at all. It also doesn’t leak like the stock system does. Extremely helpful to have a full size lift. Hope that helps.
I was online looking at the Ridetech system again last night. You get a lot for the money, but I need to save a few more bucks or sell some stuff. LOL . Thanks so much for watching and commenting!
GREAT ADVICE! I'm not if u mentioned that, it's a good practice to retorque the headers after they reach operating temp. Love you're videos. I did subscribed. I just picked up a 75 C3. I'm 68 and it's my 1st vette. Same color as yours.
Welcome to 33 mile garage, thanks for subscribing and the tip to torque the headers again after a heat cycle. Yea Marlboro Maroon is one of my favorite colors but I don’t see to many around. Enjoy the corvette!
IAM A FIRST TIME SUBSCRIBER, I HIT LIKE, WATCHED VIDEO TO THE END .IT WAS VERY INFORMATIVE, I OWN A TORCH RED 1977 CORVETTE, I HAD HOOKER HEADERS INSTALLED, HIGH PERFORMANCE INTAKE, FLOW MASTER EXHAUST, MADE A HUGE DIFFERENCE IN PERFORMANCE AND SOUND, LOL RUSS BOYD TAMPA FLORIDA...
Hi Russ. Thanks for subscribing and supporting our channel. Torch Red 77 with FlowMasters- I’m sure it looks and sounds great. It’s snowing here in Michigan today enjoy that sunshine.
Just watched this for the first time. I have a 71 small block A/T Corvette. It has headers that I might just remove after seeing this. Also it has a factory looking welded exhaust whose mufflers are intrusive on the inside rear tire clearance. Do your mufflers live completely behind the tires? That is the solution I'd want. My car has rear control arms with extra offset so I CAN fit some meat back there. Nice video, informative without a bunch of extraneous hoo hah.
welcome to the channel. So the mufflers tuck up hi and sit right behind the exhaust tips, you can barely see them and are black in color so they blend in with the under body. I have about 5 inches of clearance from the rear edge of the tire to the mufflers on each side for reference we have a P255/60/R15 tire on the car. Thanks for the comment and watching
@@33milegarage34 Yeah, my old nova was not too bad. Put some KOOKS long tubes on a 96 Z28. Had to come down from the top on one side and the other came up from the bottom. Had the front of the car about 3 1/2 feet in the air. Took a LOT of breaks. 😂😂
Thanks for the video. I have Doug's headers in route for my 68 corvette and wanted to know what type of alternator bracket you are using with the header for left side mount and where to get it.
I like the way the headers tuck in for clearance. My potential problem is I have a Ridetech suspension which has lowered the car about two inches. Obviously clearance is critical and I think the headers you installed would be ideal for my car. I think what I’m looking at on Summit is part number DOU-D350 for the headers you have. Could you confirm that as I think this is what I want to get for my car. Thanks
I purchased from summit also part number DOU-D350. I was surprised at my invoice was only $622.00 June of 2018 today almost $800. How do you like the ride tech?
@@33milegarage34 The Ridetech system is unbelievable. Well worth the money. 275/40R18 tires with no body modifications. Tires are 10 inches wide on rear and 8 inches wide on the front. Changed the whole look of the car and the handling is 21st century.
Mike, I have a 1970 LS5, do you know how much more difficult is it to install the Doug’s headers on a 454 big block? I’m sure it’s a much tighter fit trying to fish the headers into place with a BB.
I would think for a big block car you may need to take the engine mount bolts out and lift the engine up a bit to do it. I have no sponsorship from Doug’sHeader but it”s a great product that fits very good. Good luck and let me know how it goes. Thanks for watching!
@@33milegarage34 thanks Mike. I found that others have installed OBX headers on a C3 big block so I’m doing some more research on that first. Right now, one of the bolts in the front upper driver’s side A-Arm decided to come apart so I’m dealing with that and a leaky replacement BeCool aluminum radiator.
I purchased the headers from summit racing website. Search for year, engine, transmission and AC. A lesson learned the hard way for me, sometimes people use different alternator brackets that interfere with your fit. Good luck on the project.

Never seen EASY and HEADER install in the same sentence. 😁
That’s funny…. Small block corvette no problem. Big block cars are difficult. Thanks for watching!
@@33milegarage34 Yeah, my old nova was not too bad. Put some KOOKS long tubes on a 96 Z28. Had to come down from the top on one side and the other came up from the bottom. Had the front of the car about 3 1/2 feet in the air. Took a LOT of breaks. 😂😂
Now that you have a wide band O2 sensor would be interesting to see how you tune the carb. Thanks
That’s a great idea for another video.I will add it to my upcoming list. Thanks for watching.
loved it! super helpful!
Thanks Kid!
Thanks for the video. I have Doug's headers in route for my 68 corvette and wanted to know what type of alternator bracket you are using with the header for left side mount and where to get it.
I’m trying to remember, but I think I used the stock brackets and used a spacer to realign the belts. Thanks watching!

You got a link for the headers and piping materials
I purchased the headers from summit part number DOU-D350 and piping was off the shelf from O’Reilly’s. Thanks for watching!
FYI. I just checked Dougs Headers website and no headers for C3 listed, could you post the model number of the headers you did insall. thank you sir

@@33milegarage34 thank you sir
I see those dog nuts hanging from your welds on the piece you made.
That’s funny… yeah I’m an amateur welder. Thanks for watching
Long or short pipe Dougs?
Purchased the headers from summit part number DOU-D350, I guess they would be considered long tube headers. Thanks for watching
Does These headers fit 1980-1981? ;) Nice video and great sound
Double check fit up. I purchased with summit and the website was helpful. AC and bracket placement play a big roll in fitment. Thanks for watching!
It sounds fast
LoL… I wish it was faster. Thanks for the comment and watching!
454 is a lot harder than a 350. Havent found any to fit my 73 454 4 speed without denting them to fit
Agree the big block header clearance is tighter and hard to find a good set that fit correctly.
bong hahaha
Funny. Thanks for watching
