M370 to z1 intake plenum

Eighties Meta

Full bolt-ons, 100k, getting new plugs as part of scheduled maintenance and have decided to switch the m370 motordyne manifold for z1. About the same in cost as going back to stock manifold 200 or so but anyway.

I'm thinking i should probably get a retune for 300. Anyone done this exchange with no retune? I imagine it would be fine without a retune but i could i be missing 7+hp by not doing so, close to +10whp imo is worth it.

What's the thought to switch? Just something new or what?

Just have never been fully happy with the m370. So yeah, something new, the plug change is the perfect time to do so since the manifold will have to be off anyway i think.

Been thinking about the z1 manifold. Had the m370 but never ended up installing the first go around
