65 Cutlass headers for LS engine
Hi all, brand new here and really like the site. Hope I'm posting in the right section, if not please let me know. I have a 65 Cutlass with a Gen III LS engine, a 5.3L LM7 to be exact. I'm looking for recommendations on full length headers that will work with my combination. I'm looking for headers that won't rust, have good fitment, can be installed with the engine in the car and will be compatible with future mild to medium engine modifications. Reasonably priced would be nice as well, but that's secondary. Any help would be most appreciated. Below is a link to a picture of the car for anyone interested, Thanks for the help!

I too have a 65 Cutlass but with a 455 Olds and 400 trans with3.42 rear posi. Not many here put Chevy's in a Olds. Look on your Chevy sites they have it. All the 64-66 A body frames are the same just different holes for front mounts.

These are not full length but they will work in your car for the LS swap

Speed engineering has some nice stainless products for the price. They are US designed and made in China. Have seen 3 different sets in person and the quality is very nice for the $ you pay. Guy in the reviews on their site said they worked for his 65 Chevelle.

Thanks for the feeback guys! ACH1992880 I contacted Speed-Engineering and they were super helpful so I ended up ordering their headers. The reviews I've found elsewhere were good as well. Thanks for the help.

That’s the way it goes. My 64 had been sitting undriven and disassembled for 20 years.
