Header fitment question

[tazattitude]

Anyone use the Hedman 69830 on their SBC C10?
I use the CPP mounts for the engine sits forward about2-3"

Did a search for that part number, but did not come up with anything

Looks like they will work on 67 SBC truck

Thanks in advance

I did a search on Summits website but it wouldn't let me copy/paste the results. There was alot of info maybe check there.

[tazattitude]

Thanks for the reply.
Summit also says 67, but not 66.
I don't think most would since the 66 only had 327's as the small block (I think)

i would be concerned with where the collectors dump - they may just dump right into the tranny xmember - I just installed the hedman 69260 - notice how those collectors dump at a downward angle, but these 69830 appear to dump horizontal to the ground - I had a pair of Hooker Super Comps from a late 60s/early 70s blazer and the Passenger side looked pretty similar to these - could be wrong, theyre sweet lookin headers!

[tazattitude]

I pretty much have an 'open frame'. I will be going with a 200-4r. I also have the CPP trans mount. So the only thing that it would run into would be the CPP mount...don't think that would happen (or at least I hope).

notice how those collectors dump at a downward angle

Sounds like you planned on posting a pic?

Since this pic last week, I also removed the trailing arm crossmember and also going with the CPP (should be here tomorrow). This might help to since I can run the exhaust through the member.

Taz,

Sorry didnt realize your frame mods - the stock auto trans xmember seemed to be my only problem - you are probably good to go! I dont see anything that would impede

just look at the part number in summit - youll see how they differ fro yours - Id use your part number based on your crossmember setup - theyre a nicer looking header for sure!

I've got the same mounts and had a hell of a time finding the correct headers. I contacted CPPJeff here onthe board and this is what he recommends. I have yet to order the shortys, due to funds. Hope this helps.

Here you go bro hedman shorty part # 69646
hedman full length # is 69096
doug thorley # 3004
This should help you stop pulling your hair out!

Link to the shorty hedmans.



Post in my build.

I have a set of the hedman 69230's ( the same as the 69830's just not ceramic coated) that I intend to see how well they will fit the '63-'66 trucks. But I'm a long ways from that now. I think they will fit really well with the engine in the stock location and with an auto trans. I don't think you will have any issues with your engine a little farther forward. But there is a possibility. The frames are pretty much the same from 1963 thru 1972. The 327's are the same physical size as any Gen I small block.

[tazattitude]

Thanks for the replies.

Captainfab - yea, I also really don't see any issue with just moving the motor up a couple inches...or unless the frame edges come into play. Almost willing to try.
I took a risk on my BBC in a 63 and that one worked out with the motor moved up. I didn't even have remove the saginaw crossmember.

I like the looks a little better of the 69830 versus the 69096.
I did see a member doing a build with the 69096 'hedders' with the CPP mounts and looks like they worked for him.

[Captainfab]

Let us know how they work out.........

[tazattitude]

Definitely will!

[bama63]

i use these Hedman 69640 http://www.summitracing.com/parts/HE...n/?prefilter=1 for jeep engine swap but work on our trucks with plenty of clearance and short pipe hookup

[tazattitude]

Thanks guys!

prefer the long tube like the 69830

[chillware]

check out my thread in my sig, I used Hedman headers Part # 69096 w/ the CPP motor perches .. Also have the part # for the hedman shorties if you need it, got it from CPP.

Thanks Chilware. Already had a link to your build (see previous post on this thread)

I already have the Hedman 69830 ordered...rolliln' the dice.


Your build looking great. Been awhile since you've updated!

[tazattitude]

I said I would check back in and let you know the outcome of the fitment for the Hedman 69830 headers. I tried them last week, and they don't fit. The come very close, but the only reason they do not fit, is I am using the CCP perches/mounts and it moves the engine up about 2". The headers are about 1" off. So if you had a stock setup/location, I see no reason why the would not fit.

So I have a set of brand new headers for sale

So I may look into getting the hedman 69096

I got my motor finally last week, and installed it the next day!
They dyno'd it for me. Came in at 458 hp

Movin right along!!!

[chillware]

aww man thats too bad they didnt work out.. With the 69096's I had to make a small notch in the frame on both side to get them to fit.. let me know how they work out for you.. you build looks awesome man!! love the motor!

[tazattitude]

Thanks Chillware. Love your build to!!!!
Comin' along!

[Clyde65]

Taz,

Where do the headers NOT fit? is it because of the CPP mounts flip up portion on the rear of the mount? I had the same issue with them on my LSx build, along with I could have the motor that far forward.

I used POL tubular mounts which allowed me to use the rear perch mounts or the front perch mounts, which might help you....

[tazattitude]

Since the motor is moved up, of course this moves the headers up. So know where they bend to go backwards, they just hit the crossmember. They come VERY close to the CPP perches, but this would be easy to take care of.

Thanks for the info, but I already have my engine all mounted and bolted in. I'll just get the hedman 69096 like Chillware uses. CPP also recommended these.

[Clyde65]

with the motor moved up...for me it didnt work well because I was going to run an electric fan with a larger motor on it so I needed all the room between the rad and the motor that I could get. goo luck! nice build for sure!

[tazattitude]

Yea, I also ran into that problem to. I'm about 1/2" to far up so the water pump hits the fan. So I'm going with a short water pump. At least I waited to buky the pulleys and everything...I knew it was going to be close!

Thanks for the compliment on the build!

[tazattitude]

Chillware,
I do have a question. On the pic that you have on your build thread (here), it looks like the headers are pretty close to the ground. How much are you lowering your truck? I'm lowering mine 5" up front and I plan on 7 in back. You think I'll have a clearance problem?

I might consider those POL brackets and just use the headers I have.

Thanks!

[Clyde65]

I found the POL perches I told you about raised the motor up about 1" or so, with my LS it made it so I can drop the front 4" or maybe 5".

I'll have to measure the clearance of the headers when I get home from work tonight. But right now it's lowered 4" in front and 6" in back. You'll be close.. I'm still debating going to shorties one day, we'll see how much closer to the ground I get once I put the body all back on, lol

I already have the cross member from POL with exhaust cut outs for running the pipes up in the frame which was my original plan.

I had the POL engine mounts installed on my frame, and I didn't like them one bit.. they looked way to hokey.. The flat mount on the bottom doesn't sit flush on the cross member and looks plain dumb, AND I had to notch my frame to get them to fit.. if I had gone w/ the CPP mounts in the first place I wouldn't have ugly notches on the top of my frame rails now, ugh!! :S
