I need a headers for '67 Oldsmobile Delmont 88 425
thanks

 

Good luck with that. The 65-70 full size cars are unpopular and thus there is little market for the header manufacturers to spend money on development.

 

You can make them using one of the DIY header kits if you have decent fabrication skills.

 

Now I understand why I can not find anything

 

if we want to change, are a person who never pulls back.
Die Linke is where I can find these kits?
thanks

You should be able to find DIY header kits for an Oldsmobile engine from suppliers like Summit.

 

Why Headers and not just factory style dual exhaust. I assume you have a BB engine?

 

My Olds mounts originally a single exaust, I would have two.
I do not know if BB.
is a 425 low compression heads C

 

A 425 is a BB. The Left side factory style dual exhaust S manifold is reproduced and available from Thornton. The right side manifold is the same for all 67 BB engines in the B body. The crossover pipe is capped and you have a factory style dual exhaust. The auto shift linkage may need modification if using stock pipes on the drivers side. A muffler shop can bend pipes to clear the linkage on this side. Headers are not my first choice for a street car/daily driver.

 

BB is BIG BLOCK ok
Now I try to find the name I gave to the Internet.
I know it is for use quadruples but here we use it solely for these cars rallies
thanks

than my question,

my 69' olds 88 have molded sections in the chassis for dual exhaust.

it's a 350 4bll, autoshift.

what is the easiest and better to get dual exhaust with balancepipe.
2 seperate headers with seperate exhaust ore cut the exhaust after they come together and split them again.

and what size's of diam. is recommended, if the olds is reasembled again i'm going to make a exhaust of rvs steel.

 

Delta 88 is not the same as body?

 

The Delta 88 and Delmont 88 are both B bodies. Oldsmaniac has a good point, standard dual exhaust manifolds are a good choice for a street driven car. I've only heard good things about Thornton. Plus, you don't have to worry about manuafacturing anything.

 

For a street cruiser with the smallblock 350 you can run dual exhaust. One pipe on each side with no joining. You can use 2inch or 2.25 inch pipe. If you want to add a crossover/balance pipe it would be your choice but not necessary in my opinion. On a 350 engine you do not need the S manifold that the 425 would require.

 

Many thanks for your information.
I had read about for body manual body that were the same but a confirmation given by you and much better.


THANKS!!!!!!

 

found those of a Delta 425, I found them and I have used them, if they are not good hack.
thanks
