Dougs do fit great. You made right decision bout getting them raw and sending them off to get jet coat. I bought a set large tube for my stroker took bout 4 sets to get a set the coating was decent not great but ok. Then after setting in shop for a while on engine never driven they started rusting. Jegs said it was because it wasn't in a "controlled environment" a friend of mine got some went thru same problem so he sent them off got them jet coated look great been on for a year now still look new. So mine are getting pulled off an shipped to get jet coated. But they fit great

 

Thanks James
I had the Hooker's, and 2 pair of Hedman's, both were damaged during Shipping.
Wanted to share a side Pic of the Doug's installed, should be nice ground clearance.

I have had no problems with my Hooker 2457's other than the ARP bolt issue you mentioned. Original BB car. Is that a stock motor mount on the pass side?

 

Hi Donny
That is great that your Hooker 2457 Competition Headers Fit, the ones I got from Summit did not, I tried to be very accurate with what I wrote.

My Car was a 350 cu in and TH350, trans was gone when I got it, I got the Correct Frame Mounts from Ricks, and the Motor Mounts are Energy Suspension, measure out to what info I have seen.

Do you have Power Steering ? and your 2457's are Competition Headers with 2" Primaries ?

Also, I have looked at many Pictures of the 2457's, the Profile/ inset of # 5 on my set was even with # 3.
If you go to Matt's posting for "Evening with the hookers" in the Bench Racing group, Posting # 44 shows a set of Hooker 2457's Competition Headers where # 5 Drops straight down Behind the Steering Box which is Manual, Mine has Power Steering.

Last Picture is from DavePL on "Camaro Tech", He wrote SuperComps do not fit, The were 2457's - Competition and that is what My Install looked like, # 5 hit Right on the Power Steering Box and my Bolt Hole for the Motor Mount to the Frame Bracket was about 7/8" off.

And all I'm trying to show is how the Doug's D320's fit for my Install, I'm glad I borrowed a Dummy 396 Block and heads for my Mock up, and that your 2457's did fit.
I'm sure there might be a Doug's D320 set that does not fit, I feel I have all the Correct Parts for the Power Steering Install.
Timmy

 

Yes I have PS. The tubes are damn close to the PS box but do not touch. I think they are 2 inch as well. I though all of the 2457's are 2 inch ? One other thing I just remembered, I also had to shorten one each of the upper control arm bolts, on both sides, the bolts closest to the radiator/front of car. I do like the room you have with the Dougs. Anyway this was just my experience with them. It seems a slight variation of each 2457 that is produced maybe evident. Great post !!

 

I tried Hooker super comps on my 1968 that I put a 454 in. same issued a ding here and a ding there. but I changed then to herman block hugger shorties for ground clearance. after the 2" drop in the front spring I had trouble putting mine on a trailer. shorty block huggers fit and look GREAT

 

Here is a pic: They have 1,000 miles on them now.

 

i just bought a set of dougs headers hope they fit thanks for info

 

just bought a set of dougs headers hope they fit like the ones on the fhotos keep everyone updated thanks

 

Hi Johny1
Do you have a Big Block with Power Steering ?
That is what my install is.

A few things I liked about the Doug's D320-R was they were Natural Steel so I wanted to make sure they fit before I sent them out to Jet Hot, did not have to pay for Sanblasting.

Jet Hot did a beautiful Job as did Doug's Building the Headers.

They fit around my ARP Head Bolts, the hookers needed "Notching.
Ther is Plenty of room around my Power Steering Box too.

I had to Move/ Reroute the Fuel Line as the R/H # 6 Header Tube was right against the Clamp.

I also made a Heat Shield as the Power Steering did not have enough clearance to the Header Tube.

Timmy

 

my car 69 camaro convertible im doing a full restoration going pro touring i have a 502 gen5.i had hooker headers brand new withh manual steering with a little bit of massaging got them to fit. decided to go power steering bought the complete detroit speed setup no way the hooker headers are going to fit praying these doug headers do the trick

 

Hi Johny1

Wow, lot's of fun stuff.

I would like to add a Disclaimer -
My Power Steering Box is from an Iroc, Third Gen 1990 unit.

I did put my Old/ Original P/S box up and had the same easy clearance around the Box. My only Clearance issue was the Stock, Power Steering Hoses and I made a Heat Shield for that. Is your P/S Box the same Housing measurements ?

And my Engine is a "72" 454 Block with "67 - 68" Corvette Rectangular Port, Cast Iron Heads.

I do not know anything about the 502, Is it a Tall Deck, are the Exhaust Ports and Head Bolt Height the same as the Cast Iron Heads, I would think the Engine mount Bosses are in the same place.

I did use a borrowed 396 Block and Heads to check the Fitment in my Chassis with the 2 P/S Boxes and then did a Dry Fit on my 427 at the Engine Shop prior to sending out to Jet Hot.

Took a few Pics tonight, in # 3 & 5, my Fuel line Runs up over the Top of the Frame Rail and I slid the 3/8" Insulation Sleeve over the top for some Heat Protection, I am running the Mechanical Fuel Pump.

Timmy

 

Hey Timmy,
I just installed a set of D320 in my 69 SS396. What are you running for a steering column? Does yours have the back drive lever at the bottom? If so, what did you do about it? I can't move mine to get the key out right now. Will they fit with the lever in the up position? It didn't look like it.

Thanks.

 

Hi guys, In reading through this thread, I never saw anyone mention that when using a big block, the correct big block transmission crossmember must be used. If you don't the engine will be twisted on its mounts and pinch the headers at the steering box and interfere with steering linkage. See pictures.

 

Hi Tom
Yes, It is all a part of the "Swap Package" you need to either Fabricate or Purchase, I like to do as much of the Work and Fabrication myself.
Nice Pictures too !

I went from a 350SB/ TH350 to a 427BB/700R4

I did my TH400 "Crossmember Mod" for my 700R4 on Team Camaro (Cost me $60.00 from Ground-Up) as well as how I Mocked up the Engine Offset with a 396.
Both Engine and Transmission are 1/2" to the right which results in the Engine and Trans Measuring 1" less from the same Reference point on the Right side vs. the left, and my Crossmember Mod was to Cut the Mount Bracket off the Back and Weld it to the Front.

The Biggest thing about the Offset is to get the Header away from the Steering box as I have read and seen.

I had several people tell me the Hooker 2457's will fit my car "like a Glove", so I bought the 2457's and OJ Simpsons Gloves were Looser !!!

I would have had to BEAT those with an Anvil to get them to Fit, Later found out the Guy had Manual Steering or Massaged them slightly and you could not get a piece of paper down between them.

I refused to Pay that kind of money and Beat them into Fitting, obviously those issues are less with a SB.

Again, The Hooker 2205's I'm sure would fit with the # 5 Tube going up over # 7 but, at the Engine Shop, I installed 2 sets of the Doug's on Pontiac 400 engines and Liked the Fit and Quality so I gave them a try - Glad I did.

What else that I can think of -

1) With the 700R4, I had to "Beat" Yeah, (hated that) a Pocket for the Servo on the R/H side of the Trans Tunnel.
2) Engine Frame Mounts
3) Motor Mounts
4) Radiator (4 Core)
5) Upper & Lower Radiator Hoses
6) Pulleys
7) P/S Pump Brackets
8) I did Modify my SB P/S Pump to fit the BB P/S Brackets, Return Tube is different
9) P/S Hoses - Might be the Same ?
10) Fabricated a P/S Hose Heat Shield
11) Fan Shroud
12) Alternator Brackets
13) Front Coil Springs
14) Dipstick
15) Throttle Linkage to Carb
16) Headers
17) Heater Core
18) Modify the Heater Box or buy a BB Heater Box
19) Shorten the R/H Front Upper "A" Frame Bolt 1/2", will hit Header Tube
20) Move Stock Fuel Line to top of Frame
21) Add 3/8" Fuel Line Insulation
22) Shorten Driveshaft

That's it off the top of my Head.
Timmy

Well, I thought I would add my experiences with headers too. I started with a 454 engine with Hooker Super Comps 2 1/8 tubes. No problem bolted right up. They lasted around 8-10 years. BTW I have a manual steering box. The next set I bought was a ceramic coated Patriot headers, looked real nice. These were mid-length headers and fit tight around the starter and were close to the pitman arm. Plus I didn't like the way the pipes connected to the collectors. It was like in a 45* angle on the drivers side. I looked at it and stared at it until I decided to make some changes. I bought a new close ratio manual steering box with the pitman arm. Then I ordered all new ball joints, tie rod ends, and idler arm. When all my toys came in I started to work. When finished the Patriot headers were off and gone and replaced by a set of black Hooker headers 2457HKR. Now these didn't bolt up like the Super Comps did. The bottom of the flange hit on the bottom row of head bolts. I had to mark the flange on each side of the bolts. Then grind the flange until the header would bolt up. Other than the flange hitting I like the way they fit.

 

How much did Jet-Hot charge to coat the D320-R's?

 

Hi Mickey
Jet Hot was $ 400.00 with Return Shipping, it costs my Another $50.00 to Ship to them and that Included Insurance on my end thru the USPS for like $500.00 coverage.

I got them Back from Jet Hot in their own Box Wrapped and Packaged like they were Fine China.

Could not be more happier with "going the extra mile" to have the Quality and Finnish I wanted my Headers to be.

i did see someone asked about Buying them Direct from Jet Hot - Coated.
I have a nice discussion with a Tech guy and he said they stopped selling Directly thru them several years ago.

I just purchased a set of Dynatech headers for my 69 Camaro RS (327ci V8). I also received a quote from Jet Hot and plan on sending them in for coating. I selected the Extreme 1300 finish. Timmy, Is this what you selected? How long did it take to send and get them back? I like the finish on yours.

 

Hi Dom
Thanks - Yes, I got the Extreme 1300 finish.
Turn around was less than 1 week – Very Quick.

Yours look great too, are they Coated now ?

When “Shoe Horning” them into place, I used Cardboard and Blankets on the floor and just wrapped them over or held on to with a Tie Wrap her and there. Even had my Wife helping, she thought it was a Riot how I was taking so much care putting them in.

She said I was more careful with the headers than when our kids were babies.

I guess I did feel guilty

Good luck with Jet Hot, you will be impressed.
Timmy

Yes, unfortunately I had to purchase them with ceramic coating, I will send them to Jet-Hot after fitment. Cost to strip coating was quoted at $50. Appreciate the reply Timmy.

 

Thanks Timmy. I'd rather just ask a team member than go to all the trouble Jet Hot wants.
