Header install
#1
Having some headers installed on my 72 Mach 351c 4v and was wondering if you guys could tell me about how long it should take? I have the same shop where my car is for accident repairs doing this install. They are trying to charge me for 4 hours of labor to bolt them to the block. They have a lift to do this with. I’m pretty sure that I could do that in 4 hours in my garage on the floor with a bad arm!
The headers are the Hooker 6915 Competition black ceramic coated ones. I know that they fit very easily with no modifications. I have had them do a complete engine rebuild, plus other stuff and they are trying to hit me up for 1,680 bucks for them! 635 for the headers, 260 to remove exhaust manifolds and install the headers, 685 to have a h-pipe made up and connected to the headers and then connected to the existing mufflers and 100 to trailer it there and back. I know that they have to mark stuff up but this seems a bit much.
I sure would appreciate any and all responses, thanks

The hardest part in my opinion will be to get the manifolds off and the block cleaned off of the old gasket material. That in itself will take a couple hours. I just finished doing this exact job on the yellow mach 1 I had here. A couple of the bolts broke off in the block and a couple bolt heads were very rusty and rounded off. I ended up pulling the motor to make things easier. But since they just had your motor out, the bolts should come out fairly easy. Fours hours to remove the old manifolds and install the new headers seems about right. The headers are easy to install from underneath especially with a lift. $685 for an H-pipe install seems a bit high. I paid $700 for a complete 2.5" stainless system custom bent and installed with x-pipe and flowmaster mufflers. https://www.7173mustangs.com/thread-yell...in?page=17

I would find a shop that specializes in exhausts and ask them how much. Find out if they are a dealer for Hooker headers, if not buy them yourself for them to install.

I would expect your old headers would be easy to remove if they just did engine work. They are probably going to use two people to install so 2 hours each is not really over the top.
If you were here could use my lift and I would help for free.

Thanks turtle, was hoping you would reply as I know you just did this. I think the h-pipe and install is pretty high too. Can get an entire system for not much more. I just thought the 4 hours to remove the manifolds and install the headers was to long. And ya the exhaust manifolds had already been removed from the engine rebuild, so they had to come back off very easy. Plus they knew I was having the headers put on so I don’t know why they installed the engine with them on.

I already had them do it.

Ya that’s probably why they charged me for 4 hours.
Thanks David, I’m sure you would!

My $.02

As a dedicated "Mustang" shop and having just done a huge amount of work to your car, they should be embarrassed to charge you four hours for a header installation. They just had that drivetrain completely apart and the exhaust will come apart in minutes. You don't have to pad it for the inevitable broken or stripped bolts that happen with old cars.

I could do the header install with a jack and jackstands in a 2~3 hours, probably an hour with a lift. The 6915 headers are super easy to install, even the header bolts are cake. IIRC, there are maybe three that require the use of an open end wrench that you can't get a socket on.

Nearly $700 for an H-pipe? WTF....

I have to agree here. Took me all of about 2 hours to install my headers with a jack and jack stands and that included a beer or two.

73 Grandé H Code. Headman long tube headers, T-5 Transmission, 3.70 Traclok, Lowered 1" all around, Aussie 2v heads w/ 2.19 intake, 1.71 exhaust, screw in studs, full roller cam 608/612 lift 280/281 duration LSA 112, Quick Fuel 750 CFM double pumper, AirGap intake.

Thanks guys, I sure appreciate your input. I think I need to talk to them about it. I didn’t ask them before hand how much this would be, my fault for that. But I sure didn’t think they would charge me so much for this. I think they are trying to make up for some other hours that they couldn’t charge me for or something.
Things have gone pretty good with them until I got this last invoice from them. I am all for them making a buck, but I just thought this was pretty expensive, hopefully they just made an error, we’ll see. Thanks guys!
