Are there any cool aftermarket intake manifolds for these? 1999 Tahoe 5.7 vortec

Just curious, is the lower manifold bolt on a later Vortec style heads or pre Vortec style.

It's the SDPC TPI Vortec Lower on a stock L31. Some grinding required to the front accessory drive and relocation of fuel lines.

The ProFlow4 system does not look all that different than a TBI once the air cleaner is on it either. Paint the manifold black and it would have a more icognito look.

I have a Ramjet that I'm dying to use. Whether I will or not, who knows. But they are Vortec intake pattern, Edelbrock makes something similar, but can't remember the name.
