Split manifold straight 6 headers Chevy ratrod 1953 54

would be to Split a manifold on a
straight 6 in a 1953 chevy 210
or would it be better to Split
the pipe under the car
here are some pics of what
im looking to do

 

wrong forum, I think?

 

Hey,
I have split soo many of those things its not funny. Its not hard to do at all. If you can braze with brass, you can do it. What you do is the following. You need to cut a slit in the manifold between the middle and last/rear ports. In the outside face is easiest. just in the vertical side. use a cutoff wheel in the diegrinder. Slide a piece of metal inside and braze the slit closed. You are just installing the block off plate to seperate the two chambers. I know its not totally seperated but if you make the plate fit well it will be close enough. Then you need to figure out where you want or need the rear outlet to be. I liked to do mine at a 45 to the manifold but that up to you. Check throttle linkage, steering, shifter, ect. Just fab up a short length of tube with a flange welded on. Then braze it over the hole you cut in the manifold. Sounds weird but its really easy if you just take your time and think things through before just wackin and welding.

 

i dont have the stuff or the know how but
i think if i take my time i could do it but i would
like to find someone to do it for me if you know
any one let me know

thanks
