Headers after engine swap?

[chevyman07]

I swapped my 250 for a 307 using all of the factory mounts, didnt move the engine forward. It is a 3 spd on the column and the clutch hits the header I have on there now that I got from the junkyard. Which header should I use and the size also. I searched but did not find the answer I was looking for. THanx for the help.

I have Hooker comps (#2452)on mine, & have also run Hedman (69090), but my linkage is a little different than you have. You might try building a new top clutch rod with Rod ends , & heat the arm on the bellcrank, to bend it away from the headers. Im not sure how much room you need to gain to clear the tubes.....but if its not a bunch it should work. the other thing you may need to do is open up the hole in the firewall a tad to clear the new rod. If that dont work, I can tell you how to set it up with Hookers, or Hedmans best of luck L

I went with the ram horns. Would like something different, but for now....

on my 72 jimmy, the headers said they work with manual tranny, but the clutch linkage still hit, i had to re design the whole linkage, as for the ammount of offsets and other things so it would rotate and clear, you can always switch to a hydro clutch...

Did the same thing (350) on my ole '72, and bought Headman Headers for the year & MT, and they fit great. Too bad they don't fit on my current 4X4...

Thanks for the replys. 1969k10....so the hedmans will work? Do you remember which part number it was? 69090 or 69092?

Is that clutch linkage from a 67 ? I think 68 and up V8 use an offset linkage that will help clear the headers. I bought one from Billsbowtie a while back to use on our 1970 when we put headers on it. The current linkage we have looks just like yours and is from a 1967. They should be pretty easy to find.

Here is a pic of the offset linkage :

Im not positive because that is the linkage that was on the truck when I got it. It might be different between a 6 cylinder and 8 cylinder on the linkage that is.

Yes there are some differences between the 6 and 8 linkages, but it really does not matter what is on theer now, if you get an offset linkage from a v8 like in the picture, it will bolt right right on give a lot more clearance.

Hooker recomends bending the linkage on a 67 to get it to clear, but I prefer to use a factory offset linkage if possible. Maybe some other brands will clear
but the offset linkage will likely give more room with any header.
