Vortec 5.7 intake manifold

does anyone know if anyone makes performance intake manifolds that still let you run spider injectors because I found some upgraded spider injectors and just wanted to know if there’s a way around doing a carb swap and still upgrade the intake manifold

No, I don't think there has ever been an aftermarket intake for the vortec. The closest thing is the Taylor vmax spacer, which increases plenum volume and adds some top end.

I think the V-max spacer is sadly no longer in production there might be some old stock some where maybe there might be a chance of getting a used one I saw a post were some one was talking about 3d printing them do not know if it ever happened or not

I’m looking at the Edelbrock pro-flo 4 efi xt-style kit #35820, I know holly makes something similar

I would like to convert to 35823 just because the Vortec setup is so ugly. I like to be happy under my hood. But, that is way down the list!
