hello, I'm looking for a pair of 1966 330 cid oldsmobile headers. I have been searching everywhere and cant find them. any assistance on where to look or if you have some for sale will be greatly appreciated.

 

Welcome to the site, I'm assuming you want them for a Cutlass. SBO headers for a 64-67 are rare and expensive. If your just wanting duals you can cap off the cross over pipe and use you existing manifolds.

 

X2 from Oldcutlass- Whatever, your not going to gain much at all besides the "Cool Factor". Spend your hard earned $$$ on safety and reliability-these Old Old's are flying bricks.

 

thank you, this site looks like its full of great info and help. yeah looks like i forgot to mention the vehicle, it is a 66 cutlass i just picked up for my first project car everything runs great on it just looking for best performance. Thank you for that info. if i ran duals should i add an "x" or "h" pipe between them or should i just run them straight through?

 

I have not seen a set of headers for a 66-67 sbo (small block Olds) application that works. I have seen a few people put 400 bbo (big block Olds) headers on them and they hit the frame and starter and just cause huge issues. The advise you have now is to cap off the right center or forward outlet and put a nice set of dual exhaust on it. This is the best advise you can get for this. It will flow nice and have no header type related issues. You can make it sound very nice and very reliable.

Welcome you will see if you ask there is a wealth of experience on this site. Hope you enjoy your Olds.

Kooks and American Racing make headers for SBO in a 64-67 A body, very expensive. They do appear and do not last long in the parts for sale section periodically.

 

I have a set of headers for a 330(my car is a 65 f85), the headers hang to low for me to use them. If interested, pm me and we will go from there. (by the way, although I have had them on my car, they have never been fired thru, so in effect, brand new)
