Inlet Exhaust Manifold Question...!???

[Jack in the Box]

Thanks for your remarks so far, I presumed it was an aftermarket item, it has what look to be stamped GN on the manifold Flange top edge... probably the makers mark, or initials.

It's certainly a clean and unused bunch of bananas, I was just interested to know more about my new piece of automobilia to hang on the man cave wall, I have so much stuff now, you sort of inherit it as you go along...


Always interesting to know if these aftermarket parts actually worked, or not, who ever made it, even if they didn't understand the dynamics of an engines performance via the exhaust, and inlet, they certainly knew how to fabricate, and weld a nice component together, it's actually quite a nice looking piece of kit.


It would be a shame to hack a hole in your bonnet too, I agree...



Any more remarks, I'd love to hear.


Thanks again.


Stewart.

That's interesting. I have recently acquired a 4 branch manifold (but one without the inlet pipes welded on) and it is stamped on the flange with GN too and also N7. 

Does anyone know what these signify please?

I echo Stewart's comment about neat welding.

Thanks

Alan
