Cadillac 354 header options

[Jantrix]

I've got the Revell Parts Pack Cadillac 354 in a current project. I'm not thrilled with the kit headers and want some other options. I'll likely modify some other headers, but I just want to get some other thoughts on the subject. You can see what they look like here.

With their unusual port spacing and siamesed center ports, there's nothing much in the kit world that will work right out of the box. A few flathead sets of headers have 3 primaries, but they're not spaced correctly. There are cast iron OEM-style manifolds in the production-car Caddy kits, but to the best of my knowledge that's about it.

And as a side note, the "354" on these kits is a mistake. The Revell parts-pack engine represents the first generation OHV Cadillac V8 that came in 331-365-390 cubic inch displacements from the factory. I suppose you could get a "354" by boring or stroking the 331, but you couldn't tell from the outside.

I wondered about that as there was no mention of the 354 in the Cadillac motor wiki. This will help.

I'm going to try to rework the headers from the AMT Double T kit, to match the port spacing.

Solder or floral aluminum to make your own set of headers?

Not out of the question but I'm looking for a vintage speed part look.
