4.3 Chevy Custom Header Kit??

cmoultrie · Aug 21, 2013

I've done a good bit of searching with minimal results. Does anyone know where I can find a DIY 4.3 header kit? I need to build a set for my buggy due to clearance...

I've never seen a complete kit for a 4.3 but you could always get a flange and tube kit like these.

You would need some 3 pipe collectors too, unless you fab them yourself

How much clearance do you need? Old early 80s astro vans had factory tube manifolds. I had a set on my last samuria buggy and they fit between the frame rails.

I'll try to get a better picture. But the clearance issue is at the exhaust flange...

Ordered all the parts from the link below in mild steel.

Try to do some 180 degree headers on it since you will be building them. Might make it sound better.

Still sounds like a 3/4 motor but decent, headers pictured above with tru duals 2 1/4" to dynomax race bullets.
4.3 running in the trifecta, proof. Middlefangers
