Headers for a sbc 350 in a 66

[toddabrown]

We are swapping the stock 250 for a mildly built 350 next weekend. Can anyone recommend some affordable headers that will fit? We will still have our Saginaw 3 speed manual tranny and our stock steering column for now. Auto transmission and power steering are somewhere in the future.

long tubes from summit

Hedman #69260's are the ones made specifically for these trucks. Those will bolt in without any issues. You can't use just any header in these trucks when you have a manual trans.

You can also use Hedman 69090's or Hooker 2452's, but you may need to slightly modify the clutch linkage.

Those long tubes look nice but are very pricey, Turkey. Capt. Thanks for the info. Those are affordable too.

The hedman and summit catalog says the hedman will not work with a column shift 3speed. Has anyone tried to see if they will work ok?
Thanks

What is the part number of the Hedman Hedders you are looking at that say that?

I have the hooker 2452's on mine but I don't have a manual. I can say that I do like the way these headers are routed because all the spark plugs are very easy to change. In my experience most SBC cylinder#6 is always a pain to change because it is behind the tube.

[slowGN]

Part #s 69260 and the elite version 69268. Summit said they will fit all but the 3 speed column shift. They did say the hooker 2452 would fit but I've read on here you have to treak the rods.
Thanks for any belp

Knowing how the 69260's are designed, I don't see how they would not work with a 3 OTT. But then again I have not installed them on a truck so equipped.

Will the headmans collector be alot closer to the ground ? My truck is going to be dropped like 5" and dont want a scraper dented exhaust when i 2000 miles away from home at 9 pm at night ....
I am thinking about sandersons as the collector is closer to the motor and i think that i can run the exaust on the out side of the frame after the front shocks..>? I not sure that will work as the truck is in 1000 pieces...

One alternative is ram horn manifolds. You can get the vette style that has a 2-1/2" collector and then you can custom form how the exhaust pipe is routed to get around just about any configuration. That way when you eventually convert to your automatic you can easily cut your pipe and re-route the pipe itself without worrying about changing headers. Also they make plug access easy.

On my 350 swap I'm using a set of smoothie ram horns from Speedway Motors along with a 2.5 to 2.25 reducer.

I also have my engine moved to the forward position so header choices were limited as they would interfere with the crossmember. However the ram horns should produce less heat and noise into the cab (so I've been told).

With the Hedman #69260's the collector is just forward of the bellhousing crossmember and the top of the collector is just a little below that crossemember

kenfused; sweet...I wonder how they flow compared to the sandersons.?.......I not looking for 500 hp ..I am looking for great gas milage too...I have a long way to go so I like to save along the way so I can finish it ...I hear route 66 calling me......

I'm leaning toward these for my '65 K10. It has a mild 400 and a 4-speed. I'm also looking to do a single exhaust, either 3" or 4", and these will work better for that application than long tube headers.

what about a 3inch?

If you plan a automatic trans and remove the rear engine/trans crossmember you can run Chevelle/nova headers with no issues.

thats so sweet ..u could eat off that ..heh..who did the exhaust ?

[Joe Pass]

I built the exhaust using some pre bent 2.5" exhaust pipe and a Summits "X" member kit. I lucked out on the angles and just finished extending them straight back under the roll pan. I just fired up the truck for the first time this week and its not as loud as I expected it to be. I'm not disappointed but a little relieved since I'm in the process of dialing it in....Joe
I see your in Santa Rosa, what are you building ?

What year Chevelle/ Nova?? BTW awesome setup.

Thanks

[Joe Pass]

The application I used was from a 1970 Chevelle..I bought them through Summit racing. I do not remember the part number but they were around the $279 price range with the thermal coating.

You guys using the rams horns, how are you mounting the alternator? Different heads with the holes in them?

I'm using a bracket from Bills Hot Rod Company that mounts to the 2 or 3 holes on the front of the drivers side head. It doesn't require a manifold with the tab or can be used with headers.

Below is a picture from his site showing the side mount version and also a pic of the same bracket on my 350. To figure out what heads you have for the mounting holes here is a page from Bill that shows the various configurations.

If you find a set of stock GM rams horns, the LH manifold will have the alternator mounting boss cast into it, then you just need a couple of steel pieces from a mid-60's Impala to mount the alternator. Reproduction pieces are available.

I discarded the headers on my 64 C10 with 350 earlier this year in favor of the 2.5" rams horns. Here's what I learned...

The manifolds with 2.5" outlets were only used on Impalas and Corvettes. The RH manifold is the same for both cars, so the Corvette guys have bought them all up and driven the price up. A very nice reproduction is, however, available from places like Crane's Corvette Parts. The LH manifold, however (the one that mounts the alternator) is different between the Impala and the Corvette, so there is less demand. I was able to find a very nice used LH manifold (with alternator boss) for a reasonable price, and then bought the RH manifold from Crane's.

I'm very happy with the results. It cleaned up the engine compartment, and I like the sound better than with the headers.
