Re: why wont these work on our trucks
I though the 4x4s had the engine set farther back. Also has a front diff. These headers must be specifically made to fit the 4x4s particular set up.

Re: why wont these work on our trucks
K is a 4wd.
The difference may be the crossmember. If you look at the Dynomax 85023 that fit the C or K, they look darn near identical to the Flowmasters to me. I would go for it for that price and modify if necessary. Unless somebody else can see or know the difference.

Re: why wont these work on our trucks
Always call the manufacturer and do not rely on the accuracy of the Summit website. I have ran into many problems with the application section. They will even tell you to do the same if you are unsure of their data.

Re: why wont these work on our trucks
Good advice. Manufacturer should be able to tell you why it will or will not fit your particular vehicle.

Re: why wont these work on our trucks
I would say for that price, get 'em and make the neccesary modifications to fit them. I would guess the modifications will be minimal.

Re: why wont these work on our trucks
I had a set of headers I bought for my '67 C20 with the 250 ci engine.
Just not sure if it was summit or some other speed shop that I ordered them from. Will let you know once I get back home if you like.

Re: why wont these work on our trucks
The guy I got my engine from told me that the big problem with headers on a 4x4 is the transfer case. I would agree with calling the manufacturer.

Re: why wont these work on our trucks
i put a set of flowtech headers on my 67 c-10 because they were cheap.
after moving the engine back 2" having my driveshaft sortened, beating the headers, and triming the control arms. im pretty sure ill pay a few extra bucks for headers that actually fit.

Re: why wont these work on our trucks
I've heard the same story about the Flowtechs Brad_Man has. I'd get headers that fit right out of the box if it were me. Not worth the price if you bang it to fit and it still won't work. That's 130 bucks of lottery tickets you coulda bought.
