1992 k1500 Stock exhaust manifold

[Flatcap]

Good day folks
I appreciate it's a big ask but has anyone got photo's of the stock factory exhaust manifolds for a 92 K1500? I'm on the lookout here in the UK for a pair but obviously want to get it right!

I have a pair off my 88 5.7L sitting on the shelf in my shop. What size engine do you have?

It's also the 5.7 Peter!

Are all TBI exhaust manifold pairs the same other than some have AIR provisions and some don't?

I'm thinking the outlets will be in the same places, one O2 sensor bung in the left manifold, and AIR/no AIR depending on emissions requirements where the vehicle was sold originally. Heat shielding on both; a stove on the right side for the heated-air intake to the air cleaner.

VORTEC exhaust manifolds are similar, but have an additional bung on the left manifold for the convoluted tubing and fitting used on the EGR system. But plug the extra bung, and they're usable on TBI engines.

No promises on Van manifolds being the same. But I bet all the pickup and SUV manifolds are.

I've got extra manifolds on my core engines. I think they're all cracked. Be careful...

AFAIK they're all the same for 5.7L and 5.0L of course 4.3 and 7.4 are different. Mine are CA ones with the A.I.R. bungs. They can be plugged with an M22-1.5 pipe plug.

on over 8600gvw trucks there's no heated-air intake. beats me why.

but they wouldn't bolt to the tbi exhaust. you'll need to get the whole vortec system.

Both of my TBI 454s have a heated air intake; although I’m not sure if the 350s are the same way

My 350 has a heated air intake, 92 C1500
