Headers on 383

[ethurlow]

Hey guys! I have a 66 300 with a 383. I got some sanderson headers off Summit & can’t make them fit to save my life. They are hitting the control arm brackets. Wondering if I need to unbolt motor mounts & raise the engine or take it out

Probably the best bet. If they fit the car

Did you check on the Sanderson website BEFORE you bought them from Summit? They might fit the engine but NOT the chassis the engine is in. Considering that Sanderson products oritinally were oriented toward the street rod market. Which means more of a '32 Ford body rather than a C-body Chrysler body.

Yes sir I did. Called them to make sure, it is supposed to fit

 

[CBODY67]

Might they have some guidance on how to get them installed?

Couldn’t tell me a thing. Says it’s supposed to work but if I need to return I can. Absolutely all the info he said he had

Looking at Summits website only shows a center dump header for a '66 300.

I don't think that's going to work for you. The fact the person you spoke with could only say they are supposed to work, is very telling.

For reference, here's a picture of the Schumacher Tri Y headers. You can see the middle tubes are further back to clear the steering and suspension.

I have an old set of headers that came off of a '66 or '68 Fury with a 383. I have more pictures if your interested.

My experience with the Schumacher tri-y wasn’t optimal. I did a big block swap for a guy I worked with, I had everything for a nice factory appearing install including the double bell crank kickdown linkage. He bought the tri-y’s for me to install because they seemed easiest for his car. I found that you couldn’t run the factory kickdown linkage with them because of where they went in relation to the linkage boss on the bell housing. We had to use a Lokar cable unit which was less than ideal. For that reason alone, I wouldn’t run them on an automatic car again. I have yet to see a manual car with them to know if they interfere there too.

FYI, I have seen pics of people running hedman mid length headers on 383 slabs

When you say mid lengths are you talking about the ones locumob said probably wouldn’t work?

Those look like truck headers to me, very long before the curve

Center dump like that would be very difficult to bolt a pipe to even if the header itself fit. K member interference likely.

I took it one step further and went to the Sanderson web site. Their Chrysler headers are made for street rods (think 32 Ford) or the like.

I don't think that center dump header will fit either.... and then I can't see with that design that there would be any performance gain over a stock manifold... In fact, I wouldn't be surprised of a loss in performance.

 

[CBODY67]

Perhaps the center-dump headers might work on older Chryslers which had similar exhaust manifold outlet flange locations?

I have Schumacher tri-y's on one of my cars. 1966 Chrysler, 451 stroker, Edelbrock heads. I was quite happy with the ease of installation. I used a mini starter and I had to grind down a pad on the side of the block that was hitting one header (they mentioned this in the instructions). I had to remove the pin for the kickdown linkage lower bellcrank during installation, but was able to reinstall it after the headers were in.

I am referring to the 78070 hedman. I have a set on a 440 in a b body, they fit very well. I have also found pics of people using them in slab c bodies, and even trucks.

Looking at your pics, those look to fit pretty well. I liked the headers, but I don’t recall having any room for the bell crank to swing. It’s been quite a while since I did that job and don’t for sure remember the exact deal other than I couldn’t make it work. Kind of a drag, I thought the Lokar cable set up was kinda cheesy and wouldn’t last like the stock parts.

Came off a buddy's car. He was having health issues so I bought them off of him to give him a financial hand.
