Exhaust Manifolds

[erdyalx]

I'm exasperated. I have a 1980 Chevy K10 with a 350 and all smog junk is long gone. I need to replace the exhaust manifolds. I dont want headers and want to retain the preheater for the carb. Do any of you have part numbers for applicable replacements?

Looks like a solid truck.

Hooker makes some cool manifolds. Not sure if they have what you’re looking for, but a quick visit to their website ought to tell you.

I would find a set of ram horns if I were you, they are some of the best flowing manifolds produced and readily avaliable on cragslist FB market place etc.
If you dont need accessory bracket mounts I would do some of these. https://www.speedwaymotors.com/Smoothie-Rams-Horn-Exhaust-Manifolds-Small-Block-Chevy-Raw,94194.html

if the manifolds had the 8 smog tubes, I think they can be plugged with 1/8" pipe plugs.

The 63-66 corvette manifolds work nice. I had a set on my 72 GMC. I think you need two lefts (?)

There are also truck ram horns, but they have a smaller diameter (2") Depends what plans you have for your engine.
