Nice!!!! Thanks for the link!!!

T.D.Vick 12-25-2010 09:13 PM

Finally it looks like someone is making them again. I emailed Mad Dog asking about round ports too. Thanks for posting that link!

Troy

Mikes455Wagon 12-25-2010 11:10 PM

This makes me happy. I am gonna call and talk to them Monday. I hope this fixes all us G body guys header problems

ugpkgb 12-25-2010 11:22 PM

Well I think this is where it started from.
*Cut and paste only, no links please*
Find candyman and thank him. I hope to get some cash together and get a set.

Mikes455Wagon 12-26-2010 01:46 AM

If they used 301 engine and frame mounts then this is golden for me!

ponchbro 12-26-2010 09:13 AM

I hope he used 301 mount's and 350-455 engine not a 301!!!

Mikes455Wagon 12-26-2010 11:28 AM

I wish P zone would hurry up and give me permission to post so I could ask the guy what motor mounts he was using when the headers were made. In a couple pictures it looks like the motor is mounted as it was from the factory. Then in the next picture in has a plate on the front. So now I am scratching my head as to wether or not these would fit my car.

T.D.Vick 12-26-2010 12:22 PM

I emailed Mark "Mad Dog" yesterday. This is what I've gotten so far,

"I make a round port header in that design also. there not on the web site yet because its a new design.headers are mild steel and come unpainted. I sell the d-port and round port for $500. and shipping will be around $25. the round port header comes in1 3/4", 1 7/8" or 2" primary tubes. with 3 1/2" collectors."

I just replied to his email asking about the motor mount setup. I'll let you know what I hear back.

Thanks Troy. I will be watching to see what he says.

T.D.Vick 12-26-2010 08:53 PM

Well, what I received was not too convincing,

"I can build a step header for the d-port ( 1 3/4 x 1 7/8 or 1 3/4 x 2 ). I was told this is where the engines will be set in these cars but not sure what was used."

It looks like Mike is going to have to try to contact "Candyman" to be certain.

Mikes455Wagon 12-26-2010 09:47 PM

I posted a message over there to candyman and we will see what he says. I will let everyone know what I find out.

ONEFASTLEMANS 12-26-2010 10:33 PM

2inch round ports????

crossbreed455 12-27-2010 10:35 AM

Or you can just bye mine, 2" round port headers for g-body. Mine do not go around the frame like mad dogs do.
Thanks Mike. 414-840-0798

ponchbro 12-27-2010 05:13 PM

I wonder what starter was used?? The IA headers needed a mini!!!:confused:

Mikes455Wagon 12-28-2010 12:19 AM

Candyman over on the other forum doesn't check things too often I suppose. Wish I knew another way to get ahold of him....

ugpkgb 12-28-2010 12:26 AM

I think I can track him down. Have a buddy that talks to him. Will try and find out what starter he is running.

Mikes455Wagon 12-28-2010 12:50 AM

Find out if he is using the factory frame pads and engine mounts from a 301 or atleast was when the headers were built. This seems to be a big issue at hand right now.

Mikes455Wagon 12-28-2010 12:00 PM

Well I got a PM back from Candyman today. Here is what he had so say....

Hello mike yes they are 301 mounts they should fit in your car if you want any photos or have questions feel free to hit me up. the only probalm you might have is if your car sits really low. on the passenger side the number 4 tube runs really close to the control arm so if you race and the car wheelies more than a foot and a half the control arm might hit the tube but thats only if your car sits really low. the soultion i came up with was a front suspension kit from TRZ for more clearence but any cro-mo upper contol arm would work or ding the tube a little with a hammer. AGAIN THIS ONLY MATTERS IF YOUR RIDE HEIGHTS IS REALLY LOW. I hope this helps and if your not sure of anything just hit me up again and i will do all i can to help.

Hammertime Mike 12-28-2010 12:11 PM

Good info as I'm starting to build a street/strip 86 1/2 Aero Coupe. Always cheaper to buy the right parts the first time. Thanks for the info.

Cartman TD 12-28-2010 04:43 PM

anyone know prices or how to get set from "candyman" I would love to get a set for my 80 GP with a 400 in it.

ponchbro 12-28-2010 04:48 PM

They are made by Mad Dog headers. Price is $500 plus shipping. His phone # is 517-250-4487

Cartman TD 12-28-2010 05:10 PM

Ok, i just wasnt sure if they were the same guy or not. I wanted to make sure before i dropped that kind of money and they turned out to be wrong.

ugpkgb 12-28-2010 10:13 PM

Alright found out that the mounts used where stock 301. As for the starter no answer.

Mikes455Wagon 12-29-2010 12:15 AM

I have been talking with Candyman and he has been very informative. Hang tight everyone and we will get to what starter he is using.

ugpkgb 12-29-2010 10:44 PM

The starter he is runningng is a Rob Mc. Any other question let me know and I will try and get a answer for you guys. Wish I could get a set but no money.

Apparently you and I are getting the information at the same time. I am gonna call Mark in the morning and get a pair on the way. If they fit good I will take pictures and post them up. After that I will be sending them off to get coated if they do infact fit well.

ugpkgb 12-30-2010 12:21 AM

Ya sorry about that. Candyman can't post on py for some reason so will just keep relaying the messages back and forth. And Mike please post as many pics as possible.

Andy

Mikes455Wagon 12-30-2010 02:05 AM

Maybe we can work with the moderator to get him freed up so he can post here. The info he has given to us has been helpful! I will try to get pictures along the way but I have a hard time stopping to take them when I am doing something! I miss all the Kodak moments along the way for some reason LOL. Maybe I can get the girlfriend to sit and watch and take them along the way.

ponchbro 12-30-2010 02:53 AM

Pic's would be nice!!!! Hope they fit !!!! Good Luck!!!!!

Ron Landis 12-30-2010 11:28 AM

FYI...
 
I have seen the '70-up Tri-Y headers used successfully more than once. Cheaper alternative...especially for 11 sec or slower rides.

70 and up what? F-body?

ponchbro 12-30-2010 03:57 PM

They should be the Hedman 28140 3 tube headers not tri-y. Marcel from SD Performance told me he ran them on his lemans for awhile.

Ya they fit with a little bit of persuasion to the drivers side firewall and floor pan. I guess that's expected. I think I also had to clearance the lower control arms some. When I bought my 83 el camino it had them on it. It had a 400 and absolute no floor pans. I miss that pos.

ONEFASTLEMANS 01-01-2011 01:45 PM

if you dont want to go fast then put 3 tube headers on,,or just use manifolds..i know im going to order a set of the round port headers from maddog, since my old headers are getting pretty thin..but when i was moving up in engines and hp we compared 3 tubes vs 4 tubes on kres dyno, and saw a easy 30 hp increase with 4tubes and not using 2 inch hookers, and this was on a 11sec motor this was just using a set of 3,s vs regular 4tubes..and if you dont want to spend the money(which i would rather do)66-67 gto 4 tube headers from hedman can be put on with alittle work,,

Ron Landis 01-03-2011 08:54 AM

I believe...

tose are the ones my friend used. Hedman Tri-Y if I'm not mistaken. But 30 hp is over half of your typical gain from switching to headers in the first place...so it's all in what you want, I guess.

ONEFASTLEMANS 01-03-2011 08:15 PM

30hp was the gain from 3tubes to 4 tubes,, not from manifolds

Mikes455Wagon 01-05-2011 12:20 AM

Well my headers showed up today and I haven't saw them yet. I had them shipped to my dads as I didn't want them laying on the porch at my town house for everyone to see. From what I am being told from my dad, they look pretty nice(and he is picky). Something that I was not aware of is the front tube on the passenger side is a slip in tube. I won't weld it in for a race car but it is something to be considered for the street car folks. I will post more when I have more info.

crossbreed455 01-05-2011 10:16 AM

It has to be a slip tube because it wraps around the frame. There is no other way to do it with these frames in a g-body car. Been there, that's why mine where custom made because I did not want one tube to go around the frame and nobody made a good set with the right tube thickness. Just because the passenger side sits a little forward.

Thanks Mike

Mikes455Wagon 01-06-2011 01:23 AM

The gentleman that had the first set made for his car contacted me to let me know that they do not go around the frame. They were made in two pieces so they could be installed without having to raise the engine to get them in the car. Hopefully this weekend I will get to putting mine on and get pictures up for everyone to see.

Mikes455Wagon 01-08-2011 06:54 PM

Well, I have mine on the car and took some pictures before removing them to get them coated. They fit wonderful and I believe a stock starter will still fit. They headers look like they are gonna be our header solution. The only spot I found that was tight was the drivers side collector flange is very close to the floorboard. I spoke with Mark and will be sending him pictures so he can adjust this on the next set. I will say Mark seems to be a GREAT GREAT guy to deal with and I am very happy with the work. I will get pictures up as soon as I can.

Mikes455Wagon 01-08-2011 11:58 PM

Here are some pictures...enjoy!

Cartman TD 01-09-2011 02:35 AM

SWEET!!!!!!! They look great! I found what my next project is going to be for my GP once i get the carb rebuilt. :)

ponchbro 01-09-2011 09:39 AM

Thanks for the picture's!! Like you said it would be nice to see the driver side dropped down just a bit!

ONEFASTLEMANS 01-11-2011 11:09 PM

those look better than my old indian adventure headers ever did..

matt65 01-12-2011 02:18 AM

Yeah, that crazy bastard held me at knife point while I trailered his car all the way there and back!

Mikes455Wagon 01-13-2011 12:55 AM

All that sounds like something my friends would say about me!

RA462 01-13-2011 01:06 PM

Good to hear someone is making headers for REAL G-Body Pontiacs.

ONEFASTLEMANS what are you using for headers for your car?
